Abstract:

Pelite® is a polyethylene closed cell foam commonly used as an interface material in prosthetics. Both normal and vacuum-formed Pelite were tested under compression and under shear loading. For shear testing, the results were not significantly different for normal and vacuum-formed Pelite. For normal Pelite, the slope of the stress-strain curve was 1.17MPa (±0.14) while for vacuum-formed Pelite it was 1.24MPa (±0.22). Compressive results, however, were significantly different. Below 80kPa of applied compression, the slope of the stress-strain curve for normal Pelite was 0.99MPa (±0.11) while for vacuum formed Pelite it was 0.72MPa (±0.12). Between 80kPa and 200kPa of applied compression, the slope of the stress-strain curve for normal Pelite was 0.45MPa (±0.03) while for vacuum formed Pelite it was 0.55MPa (±0.05). Reasons for the differences and their significance to interface mechanics and computer-aided prosthesis design are discussed.

Abstract:

The Caledonian Horn Head Slide is a spectacular ductile shear zone transecting Neoproterozoic Appin Group Dalradian metasediments in Donegal (NW Ireland). Two conflicting stratigraphic interpretations exist for the inverted succession exposed in the hanging wall of the structure. These are based on correlation with two quite separate exposed pelite formations elsewhere. The two formations are lithologically indistinct and unfossiliferous. Here we document the novel use of assayed and logged spectral gamma-ray measurements in comparing the contentious pelite in the hanging wall of the Horn Head Slide to the two possible correlative pelite formations from a wide area of their unequivocal outcrop. The data from the contentious pelite show a clear statistical and stratigraphical affinity with one candidate unit only, thus providing the stratigraphical definition necessary for refining previous cross-sections. A new model, based on our spectral gamma-ray correlation, is proposed to account for the northwestwards directed emplacement of the Lower Falcarragh Pelite Formation along the slide. This model requires pre-Caledonian normal faulting as a precursor to the ensuing compressional event in which stratigraphically younger rocks were thrust over older, a common instance in fold and thrust belt geometry. Our work suggests that spectral gamma-ray measurements may provide a rapid, field-based method for differentiating unfossiliferous pelite or mudstone units at outcrop and in geophysical well-logs, even in structurally complex areas.

Abstract:

The Hadrynian (Late Proterozoic) Kaza Group is 3800 m thick in the southern Cariboo Mountains of south-central British Columbia, and it consists of a lower division of pelite and psammite (700 m), a middle division of granule conglomerate with thick pelite intervals and some quartzite and carbonate (1400 m), and an upper division of granule conglomerate with little pelite (1700 m). Contacts with both the overlying Isaac Formation of the Cariboo Group and with underlying marble, semipelite, and amphibolite are gradational. The underlying strata can be traced southeastward into the middle marble and the semipelite–amphibolite division of the Hadrynian Horsethief Creek Group. The upper clastic division that caps the Horsethief Creek Group in the Selkirk Mountains is a southeastward-thinning equivalent of the Kaza Group.Two southeastward-tapering wedges of granule conglomerate, pelite, and carbonate constitute the bulk of the Hadrynian Windermere Supergroup of southern British Columbia. The lower wedge is represented by the Horsethief Creek Group, exclusive of its upper clastic division. The upper wedge is represented by the upper clastic division, the Kaza Group, the overlying Cariboo Group, and the middle and upper Miette Group. The two wedges indicate two pulses of crustal thinning and stretching during Hadrynian rifting of western North America.

Abstract:

Purpose. This study aimed to compare the effect of satisfaction and perceived problems between Pelite, Dermo with shuttle lock, and Seal-In X5 liners on the transtibial amputees.Material and Methods. A total of thirty transtibial amputees (17 male, 13 female) volunteered to take part in this research. Two prostheses were fabricated for each participant. Prosthetic Evaluation Questionnaire (PEQ) was filled in by the participants with the three liners.Results. The statistics highlight that Dermo liner showed significantly higher score (P=0.05) in walking, walking on uneven surfaces, stairs walking, fitting, donning/doffing, sitting, suspension, and overall satisfaction with Dermo liner compared with Seal-In X5 and Pelite liners. Overall satisfaction was 34% higher with Dermo liner than Seal-In X5 liner and 28% higher than Pelite liner. Participants reported less problems with Dermo liner and significant differences (P<0.05) were recorded between the three liners in sweating, skin irritation, frustration, and pain compared with Seal-In X5 and Pelite liners.Conclusion. Participants experienced high level of satisfaction and practiced fewer problems with Dermo liner. These results showed that there is good indication to believe that Dermo liner might be a good choice for transtibial users and might help the clinicians and prosthetic practitioners in selection criteria of prosthetic liners.

Abstract:

The article presents the results of research of bottom sediments of rivers of two main river basins of East Donbass - Seversky Donets and Tuzlov. In the rivers Seversky Donets basin, the distribution of trace elements (Fe, Mn, Pb, Cu, Ni, Cr, Zn, V, Sr) was found to be characterized by large variations, largely due to the more heterogeneous granulometric composition of river alluvium. As a result of the analysis of heavy metals, distribution in heavy, sandy-aleurite and pelite fractions, the value of the latter as the main carrier of trace elements in bottom sediments was revealed. The calculation of the total level of bottom sediments contamination of gross samples and the pelite fraction showed that, in general, the rivers of the region have a weak level of pollution. It has been established that it is the pelite fraction gives the most objective information about the aquatic environment.

Abstract:

AbstractThe mineralogical characteristics of halloysite in rectorite pelite in the Zhongxiang area, Hubei, China, were investigated using X-ray diffraction, scanning electron microscopy and high-resolution transmission electron microscopy methods. The results show that halloysite crystals exhibit euhedral lamellar, tubular or club-like, and needle-like or fibre-like morphologies, indicating that they crystallized from a significantly water-saturated environment. The mineral assemblage of the rectorite pelite is rectorite, halloysite, illite, gypsum, pyrite and rutile, suggesting a weak supergene alteration. Several features related to crystallization of halloysite were noted. Growth of halloysite on rectorite edge surfaces in voids and twins of halloysite on a nanometer scale with composition plane (110) were found in the Zhongxiang rectorite pelite, and, in particular, the tapered ends of tubes suggest that halloysite crystallized from solution. Disaggregation of lamellar halloysite particles into parallel clusters of single tubular halloysite crystals suggests that because of significant [H2O] activity in the environment, halloysite may have been derived from the alteration of rectorite.

Abstract:

Quesnel Terrane, at Quesnel Lake, consists of two regional Triassic–Jurassic age-equivalent units, the Takla–Nicola and Slocan – King Salmon assemblages, as determined from conodonts and macrofossils. The upper mainly volcanic unit (Takla–Nicola) overlies the mainly pelitic unit (Slocan – King Salmon) and was probably emplaced by thrusting. The lower unit consists of dark grey pelite, siltite, limestone, and lesser amounts of fragmental basalt and greywacke. The upper unit consists of fragmental basalt, diorite, greywacke, and lesser amounts of dark grey siltite and pelite and limestone. The unit age and stacking order suggest that during the Jurassic, the volcanic-rich thrust sheet was transported northeastward over an eastern, more pelitic facies of the terrane. The northwesterly trending thrust trace is approximately 300 km long. The Triassic and Lower Jurassic subduction-generated volcanic unit may have been deposited on sediments and volcanics equivalent to the upper Paleozoic Harper Ranch Group; the eastern Triassic and Lower Jurassic pelite unit may have been deposited on the pillow basalt and ribbon chert of the upper Paleozoic Slide Mountain Group. The upper Paleozoic Harper Ranch and Slide Mountain group rocks may have rested on attenuated North American crust.

Abstract:

The distribution of the rare-earth elements (REE) and Th in the suspended particulate matter (SPM) of some large Russian Arctic rivers and in the bottom sediments from the mouth zones of the world rivers of large categories/classes is compared. It is concluded that the fine (pelite and silt-pelite) material of the Russian Arctic rivers belongs mainly to classes 1 + 2 (large rivers and rivers draining areas made up mainly of sedimentary rocks) and 4 (SPM of rivers draining volcanic areas) of the world rivers. The SPM similar in terms of REE and Th distribution to the bottom sediments of the mouth zones of category/class 3 (rivers draining mainly metamorphic/magmatic terranes) are not typical of the Russian Arctic rivers, except for the SPM of the Lena River similar in terms of (La/Yb)N and Eu/Eu* ratio.

Full text

Abstract:

The style of extensional quartz veins changed during deformation and metamorphism of greywacke–mudstones near Yellowknife, with successive types of veins accompanying a progression from steeply plunging, predominantly macroscopic F1, and F2 folds to mesoscopic F3 folds and subvertical S3 axial planar cleavages. (A) Early-stage multiple bedding-parallel veins are confined to pelitic units. Some form saddle reefs around hinges of F1 and a few later folds, whereas others are unrelated to fold hinges. Emplacement of most bedding veins during or before F1 folding is suggested. (B) Echelon veins pre-dominantly lie stratabound within pelites. Folding about S3 cleavage indicates a pre-F3 or early F3 origin. (C) Foliation veins more commonly cross sandstones than pelites and follow S3 or F3 axial surfaces. Boudinage of the veins indicates emplacement before S3 was fully developed. (D) Sporadic veins, discordant to bedding and cleavage, vary from undeformed to folded about S3. Evidently these veins were emplaced towards the end or after F3 folding.The change from pelite as the preferred host rock for bedding and echelon veins to sandstone for foliation veins could reflect migration of loci of hydraulic fracturing as fluid was produced and lost during metamorphism. Bedding and foliation veins apparently followed weakness planes (bedding fissility and cleavage), whereas the echelon vein arrangement suggests that during an intermediate stage of deformation pelites acted as shear zones. All veins could have formed during variably directed, subhorizontal, tectonic compression.

Abstract:

Quarrying activity concerning “Pétra Thymianón” (= Thymianá Stone) is located in the homonymous region of Chios Island. This structural stone is experientially classified into four commercial types, bearing the quarrymen jargon names: “Hemískliri” (= Medium Hard), “Triandafylli” (= Rose Pink), “Malaki” (= Soft), “Melidjani” (= Purple). All those types consist mainly of carbonates. In a lesser extent, quartz, leaf-shaped minerals, and iron oxides – hydroxides occur. Geologically, Thymianá Stone is characterized as “Carbonaceous - Ferruginous Pelite”. It is a sedimentary thin-bedded rock with alternating layers of calcareous pelite and ultra fine-grained sandstone. Very low grade metamorphism is also present. The quarry production consists of blocks, being cut to slabs for paving and flooring and to shaped stone units for masonry. In this study, the physical mechanical properties of the various Thymianá Stone types have been determined according to the relevant EN Standards. Furthermore, the physical meaning of the quarrymen jargon has been established in connection with the stone types’ quality characteristics and potential applications.

Abstract:

ABSTRACT: The Piriá Basin (Piriá Formation) is a hemi-graben shaped basin that developed over Precambrian rocks of the Gurupi Belt. The lithological content comprises four interfingered lithofacies: (1) arkose and greywacke with pelite layers, (2) laminated siltstones and pelites, (3) arkose with hummocky stratification, and (4) oligomictic conglomerate. This sequence was formed in alluvial fans (conglomerate), and fluvial systems (arkose, greywacke, siltstones and pelites) that were established and evolved during the migration of the subsidence. The sedimentary sequence underwent anquimetamorphism and very weak tectonic deformation. U-Pb analyses of detrital zircon set the maximum depositional age at 591 Ma and indicate several sediment sources, that range in age from the Neoproterozoic to the Archean. The main sources are from the Rhyacian, which is the main period of continental crust formation in the São Luís cratonic fragment and the basement of the Gurupi Belt. Neoproterozoic sources were important in the eastern segment of the basin. Ages from unknown sources in the region so far have also been recorded. Combined, the U-Pb zircon data, the whole-rock geochemical and Sm-Nd results, and the petrographic information revealed proximal felsic to intermediate provenance, in addition to recycled sedimentary sources. As a whole, our data suggest that the Piriá Formation was deposited in a post-orogenic basin related to the final stage of evolution of the Brasiliano cycle of orogenies, which built up the Gurupi Belt.

Abstract:

Temporal variations of the three components of the geomagnetic field were recorded at eight sites along a 240 km profile across the Early Proterozoic Wopmay Orogen. After an empirical separation of these data into normal and anomalous parts, horizontal-to-vertical-field transfer functions in the period range 40–1200 s display evidence for a minor anomaly spatially located near the allochthonous shelf margin at the eastern edge of the Hepburn Batholith. The observations can be partially simulated by a two-dimensional 20 ? m body (30 km wide, 2 km thick) embedded in the surface of a very resistive layered Earth model derived from inversion of magnetotelluric sounding data at a central station. The body correlates spatially with metamorphosed graphitic pelites of the Odjick Formation (Epworth Group), a unit of deep-water facies interpreted as continental slope–rise deposits. Laboratory measurements on samples of the pelite yielded resistivity values of the order of 104 ?∙m, so the enhanced conductivity of the body is more likely caused by water filling cracks associated with the pelites' well-developed cleavage and schistosity, rather than by the graphite. A scalar audiomagnetotelluric survey across the Wopmay fault zone, a prominent structure that bisects the orogen, gave results very much distorted by three-dimensional effects. The electric-polarization apparent resistivities of these data indicate a shallow conductor 2 km east of the fault scarp, 1–2 km wide. Models of the feature suggest that its vertical extent is at least 1–2 km.

Abstract:

ABSTRACTAir photo interpretation and geochemistry have been used to supplement sparse field data in compiling a reconnaissance geological map of the area around the Lecht. Upper Appin and lower Argyll Group rocks are exposed, the best marker horizons being correlatives of the Appin and Jura Quartzites. Scatter plots, Q mode factor analysis and Pearson correlation coefficients of geochemical data were successfully used in the correlation of the pelite and limestone outcrops. The presence of major recumbent folds is inferred. The area is cut by numerous minor faults which are thought to be related to a major transcurrent fault, the probable north-eastern continuation of the Loch Tay fault, which was active in Lower Old Red Sandstone times.The Lecht manganiferous ironstone is a seepage-bog ore type deposit derived by weathering of the local Dalradian sequence. Despite intensive leaching, this sequence still shows anomalously high levels of several elements, particularly Mn, Ba and Zn. In addition, stratiform sphalerite and manganiferous garnet are present in Blair Atholl Subgroup limestone and pelite horizons, respectively. Mineralogical and geochemical evidence suggests the presence of Zn–Pb–(Ag)–(?Au) exhalative mineralisation within the upper Appin Group Dalradian of the region, of which the Lecht represents the distal manganiferous expression.

Abstract:

AbstractReconstruction of the protolith lithostratigraphy of amphibolite-facies metasedimentary rocks of the Greater Himalayan Series (GHS) in Nepal documents a single, long-lived passive-margin succession that was deposited along the northern margin of the Indian Craton. In the Langtang area, Paleoproterozoic gneisses are unconformably overlain by a succession of upper Neoproterozoic–Ordovician fluvio-deltaic quartzite, basinal pelite and psammitic beds that grade upsection into micaceous semipelite and pelite. U–Pb zircon geochronology yields maximum depositional ages between c. 815 and 460 Ma for the GHS in Langtang. Regional variations in the composition and thickness of the GHS along the length of the Himalaya are attributed to siliciclastic depocentres centred on Zanskar in northern India, Langtang and Everest in central to western Nepal, which contrast with coeval marine carbonate shelf deposition in the Annapurna region. The protolith lithostratigraphy documented for Langtang provides a coherent framework for interpreting subsequent Cenozoic Himalayan deformation, specifically the homogeneously distributed layer-normal shortening (i.e. flattening) and layer-parallel stretching (i.e. transport-parallel stretching) that characterizes the GHS. Within the context of a single protracted northern Indian marginal sedimentary succession, the distinction between the Lesser, Greater and Tethyan Himalaya is structural rather than lithostratigraphic in origin.

Full text

Abstract:

ABSTRACT:After many years of systematic experimental investigations, it is now possible to quantify the conditions for optimum fertility to melt production of most common crustal rock types as functions of temperature and to about 30 kbar pressure. Quartzo-feldspathic melting produces steady increases in melt proportion with increasing temperature. The exact melt fraction depends on the mineral mode relative to quartz-feldspar eutectics and the temperatures of mica dehydration melting reactions. Mica melting consumes SiO2 from residual quartz during the formation of refractory Al2SiO5, orthopyroxene, garnet or cordierite.A simple graphical interpretation of experimental results allows a deduction of the proportions of mica and feldspar leading to optimum fertility. In effect, the mica dehydration melting reactions, at specific pressure and are superimposed on quartz-feldspar melting relations projected onto Ab-An-Or. Fertility to melt production varies with the mica to feldspar ratio and pressure. Pelites are more fertile than psammites at low pressures (e.g. 5 kbar), especially if they contain An40 to An50 plagioclase. At higher pressure (e.g. 10-20 kbar) and for rocks containing albitic plagioclase, psammites are more fertile than pelites. For a typical pelite (e.g. with An25 at 20 kbar), the cotectic with muscovite lies at higher (≍·) and XAb (≍0·42) than with biotite :≍0·35; XAb(≍·), thus dehydration melting of muscovite requires 10% more plagioclase for fertility than does biotite.The first melts from dehydration melting of muscovite (with Plg + Qtz) are more sodic and form at lower temperatures than the first melts from Bio + Plg + Qtz. With increasing pressure, to at least 30 kbar, granite minimum and mica dehydration melts become more sodic. This indicates that of such melts is greater than 0·3.

(2) the effect of a combination of repetitive shear and compression. (3) the force-distribution (force-attenuation) properties of these materials, both when new and after repeated compression. The last function represents a model for relief of pressure beneath plantar bony prominences, a topic of special concern for the insensitive foot.

Abstract:

U ovome radu analiziraju se kvalitativna svojstva peleta izrađenih iz vrsta drva turopoljskog kraja – sadržaj pepela, ogrjevna vrijednost, gustoća peleta i tlačna čvrstoća. Prikupljeni su uzorci hrasta lužnjaka (Quercus robur L.), običnoga graba (Carpinus betulus L.), poljskog jasena (Fraxinus angustifolia Vahl.), crne johe (Alnus glutinosa L.) i crne topole (Populus nigra L.). Prikupljeni i okorani uzorci usitnjeni su na mlinu s noževima na granulaciju 2,00 mm. Na uzorcima je ispitan sadržaj vode, pepela i ogrjevna vrijednost. Sadržaj pepela određen je zasebno za koru i drvo. Sadržaj pepela u kori pokazuje visok udio kod hrasta lužnjaka koji iznosi 13,64 % i graba sa 11,91 %, dok je kod ostalih vrsta udio pepela u kori između 7 i 10 %. Sadržaj pepela okoranog drva pokazuje vrijednosti 0,63 % za hrast, 0,50 % za jasen, 0,46 % za grab. Vrijednosti sadržaja pepela kod johe i topole bile su oko 0,4 %. Rezultati ukazuju na potrebu okoravanja u proizvodnji peleta s ciljem postizanja kvalitete peleta klase A1 i A2. Određivanjem ogrjevne vrijednosti najbolji rezultati utvrđeni su kod uzorka drva crne topole koja iznosi 19,63 MJ/g, a najmanja vrijednost izmjerena je kod uzorka graba 18,94 MJ/g. Nadalje, navedeni uzorci pomiješani su te su fomirane 3 grupe mješavina. Udio tvrdih vrsta listača hrasta, graba i jasena u svakoj pojedinoj mješavini bio je 60 % dok su u preostalom udjelu od 40 % jednoliko sudjelovale joha (20 %) i topola (20 %). Formirane mješavine materijala JTJ (jasen 60 : topola 20 : joha 20), HTJ (hrast 60 : topola 20 : joha 20) i GTJ (grab 60 : topola 20 : joha 20) prešane su u pelete uz pomoć hidrauličke laboratorijske preše pri 2 veličine sile (3,0 i 6,0 kN) i 2 temperature (150 i 200 °C). Po isprešanju, peleti su ostavljeni 15 dana da se dimenzijski stabiliziraju te su im određene dimenzije i gustoća. Peleti su potom ispitani na tlačnu čvrstoću u radijalnom smjeru pomoću kidalice. Peleti iz svih mješavina, prešani silom 6,0 kN kod temperature 200 °C pokazali su visoku gustoću koja je bila u rasponu 1 207 – 1 234 kg/m<sup>3</sup>. Peleti osnovne mješavine jasena dali su kod sile 3,0 kN i temperature 200 °C vrlo visoku gustoću od ≈ 1200 kg/m<sup>3</sup>, dok su općenito najmanju gustoću imali peleti osnovne mješavine graba kod svih režima prešanja. Rezultati tlačne čvrstoće u radijalnom smjeru pokazuju najbolje rezultate kod peleta prešanih pri 6,0 kN i 200 °C i to 13,59 MPa kod osnovne mješavine jasena, 11,1 MPa mješavine hrasta i 9,06 MPa mješavine graba. Ako se tlačna čvrstoća peleta promatra zbirno prema mješavini, značajno bolje rezultate daju peleti izrađeni iz mješavine jasena, topole i johe u usporedbi s ostale dvije mješavine.

Abstract:

Gold-bearing quartz veins were recently discovered in archimetamorphic quartzite–rudite and quartzite–pelite sequences of the Lower Cambrian McNaughton Formation in the main ranges of the central Canadian Rocky Mountains. There are two distinct vein types: an early syntectonic, syn- to postmetamorphic, auriferous, bedding-parallel type, generated during repeated northeast-directed compressive tectonism; and a late, postpenetrative deformational discordant type, which contains only minor gold (<500 ppb Au). Gold emplacement and discordant veining were confined to the onset of late compression leading to development of the Chatter Creek Fault.The spatial distribution and dimensions of the veins attest to mechanically founded lithologic anisotropy. Bedding-parallel veins are confined to less competent, volumetrically minor pelitic rock types. Discordant veins are confined to competent quartzitic units.Bedding-parallel vein filling took place in two paragenetic stages: a protracted, pre-gold stage (quartz ± minor white mica and pyrite) depositing over 90% of vein material; and a late gold-bearing–post-gold stage (quartz–pyrite–gold–galena ± white mica and Fe carbonate). Gold usually occurs in association with brecciated pelites and penecontemporaneous sulfides. Discordant veins (quartz ± minor pyrite) record a single stage of vein filling broadly coeval with gold deposition. Minor hydrothermal alteration (pyrite ± white mica ± carbonate) of adjacent wall rocks accompanied gold emplacement and is mineralogically congruent with the regional archimetamorphic and bedding-parallel vein assemblages.In terms of their setting and morphology, the Athabasca Pass gold lodes are viewed as a siliciclastic-hosted analogue of the turbidite-hosted class of gold deposits. Principle geochemical differences from published process models for turbidite-hosted gold deposits are a function of the mineralogical maturity of the siliciclastic host strata in the Athabasca Pass.

Abstract:

The objective of this study was to determine the proportion of sand, solarized manure, vermicompost and soil capable of increasing tomato fruit yield and lycopene content. The treatments were: T1: 80 % Sand- 20 % Vermicompost (SV), T2: 80 % Sand- 20 % Solarized manure (SSM1), T3: 80 % Sand - 20 % Pelite ?Steiner solution (SPSS), T4: 80 % Sand- 5 % Soil - 15 % Vermicompost (SSoV), T5: 85 % Sand - 15 % Solarized manure (SSM2) and T6: 80 % Sand - 5 % Soil - 15 % Solarized manure (SSoSM). The organic substrates T5, T4, T1 and the control (T3) obtained larger fruits and yields. The lycopene content in tomato fruits grown in the organic substrates was 26 % higher than that obtained in the control treatment. Organic fertilizers improve the nutraceutical quality of tomato fruits, without signi cantly degrading yield.

Abstract:

Recent investigations (Walker & Rees, 1980; Davis & Wilson, 1983b) have shown that the protobranch bivalve Nucula turgida (Leckenby and Marshall) occupies an important niche in the ecology of Dublin Bay, where it is the dominant organism over much of the southern part of the outer bay. This is an area of moderately sorted fine sand (Harris, 1980) with a pelite (silt and clay) fraction of less than 10% and a consequently low percentage of organic matter of around 1% (Davis & Wilson, 1983 b). Trevallion (1965) described the N. turgida habitat as one of firm muddy sand, adding that the animals avoided mud due to their inability to maintain position or feeding and respiratory currents and also avoided gravel due to their inability to burrow in coarse substrates.

Full text

Abstract:

The northwestern boundary zone of the Central Metasedimentary Belt (Grenville Province) in the Haliburton area (Ontario) is a stack of alternating tonalitic and syenitic crystalline thrust sheets, transported toward the northwest on out-of-sequence, upper amphibolite facies, ductile thrust zones during the Grenvillian Orogeny, at 1060 Ma, approximately 100 Ma after the initiation of thrusting in the underlying Central Gneiss Belt. Kinematics of the deformation are complex. Predominant northwestward thrusting was, at least partly, coeval with subordinate northeastward thrusting. Late synmetamorphic extensional shears cut both thrusts and thrust sheets. Minor late thrusting on discrete ductile shear zones postdates the extensional structures. Belts of mechanically weak pelite(?) appear to have localised the thrust sheets. Highly mobile marble behaved as a relatively low viscosity fluid during transport, able to intrude and erode more competent wall rock.

Abstract:

Jurassic dioritic to granitic igneous rocks extensively intrude into the southern Korean Peninsula, including the Yuseong area located at the boundary between the southern margin of the Gyeonggi Massif and the northern margin of the Okcheon Belt. In this study, the petrogenesis and sources of Jurassic igneous rocks in the Yuseong area were investigated. The U–Pb zircon age data from the Jurassic plutonic rocks in the Yuseong area give two igneous ages, ca. 178–177 Ma and 169–168 Ma, indicating that two stages of igneous activity occurred in the Yuseong area during the Jurassic. The geochemical characteristics of Jurassic diorites indicate that they originated from enriched mid-ocean ridge basalt (E-MORB; Nb/Yb = 5.63–7.27; Zr/Yb = 118–156). The enriched Th/Yb ratios (5.5–8.0) in the diorites imply that they experienced crustal contamination during magma ascent. The Jurassic granitoids in the Yuseong area are divided into I- and S-type granites. The Jurassic I-type granitoids may have formed via the partial melting of mafic rocks with mixtures of 10–40% pelite-derived melt, while the S-type granites originated from felsic pelite. The Jurassic diorites have low Nb/Th ratios with depletion of the Nb and Ta components, indicating that they formed in a volcanic arc tectonic environment. On the other hand, the Jurassic granitoids show two different tectonic environments: a volcanic arc, and a syncollisional environment. The granites with syncollisional character are S-type granites, and may give incorrect information about tectonic setting because of the changes in the trace elements of the S-type granite due to fractional crystallization. Early Jurassic (200–190 Ma) igneous rocks are distributed only in the southeastern Korean Peninsula, including the Yeongnam Massif; Jurassic igneous rocks formed at ca. 190–180 Ma occur mainly in the Okcheon Belt and southern Gyeonggi Massif, which includes the Yuseong area. Middle Jurassic igneous rocks widely intruded from the Okcheon Belt, through the Gyeonggi and Nangrim massifs in the Korean Peninsula, to the Liaoning area in the North China Craton at 180–160 Ma. This distribution pattern of the Jurassic granitoids suggests that flat subduction started after 180 Ma in Northeast Asia.

Abstract:

The article deals with the results of studied structure features of reservoirs in productive zeolite-containing rocks. We have established that the content of pelite fraction and carbonate content have impact on the deterioration of reservoir properties, and the development of zeolitization is characteristic for zones of improved reservoir properties.It is shown that the presence of the core glow in the ultraviolet light for zeolite-containing rocks doesn’t guarantee the receipt of the product during testing and will depend on the thickness ratio with different intensity of luminescence. The change in wettability of the rock in the reservoir conditions, an increase in the share of residual oil, and the presence of oil in the dead-end pores are the most likely explanation for the described situation. If the core luminescence is «weak», the product from the reservoir can only be obtained by applying special impact methods.

Abstract:

Amphibolite-facies Settler Schist in the southeastern Coast Mountains of British Columbia has long been correlated with Chiwaukum Schist of the Cascade metamorphic core, North Cascade Mountains, northwestern Washington. The additional correlation proposed here of Settler Schist with Darrington Phyllite and Shuksan Greenschist (and blueschist) of the Northwest Cascade System in Washington is based on along-strike near-continuity of outcrop areas, a similar protolith composition range, the same structural position relative to the Shuksan fault zone, and distinctive irregular structures in variably metamorphosed sandstone and pelite of both Darrington Phyllite and Settler Schist. If this correlation is valid, then the record of Early Cretaceous; subduction-related blueschist metamorphism of Shuksan–Darrington rocks was destroyed in Settler Schist by overprinting by early Late Cretaceous Barrovian metamorphism; only some distinctive, premetamorphic structures remain. The implication is that within the southeastern Coast Mountains, a cryptic record of subduction is overprinted by Barrovian metamorphism.

Full text

Abstract:

AbstractThe albitisation of pelitic metasediments to form adinoles adjacent to minor mafic intrusions has in the past been attributed to Na-bearing metasomatizing fluids emanating from the intrusions themselves. The chemistry and mineralogy of adinoles associated with dykes forming a high-intensity swarm in the Tallaght area, County Dublin, Ireland, confirms a metasomatic origin for the adinoles described, with Na and to a lesser extent Ca introduced into the country rocks at the expense of K. We suggest, however, that the source of the metasomatizing fluids was external to the dykes — possibly involving a hydrothermal system driven by an underlying magma reservoir that was parental to the dykes and also contributed volatiles to the hydrothermal system by degassing. Heat flow from the dykes was instrumental in promoting the reaction between muscovite in the country rock pelites and the Na(Ca)-bearing fluids to form albite, temperatures of ∼350°C in the country rocks within a metre of the contact being indicated. The mechanism of adinolization proposed is shown to be compatible with recent experimental work on the hydrothermal alteration of greywackes and basalts and also with the likely temperature gradients adjacent to dykes.

Full text

Abstract:

The extent of elemental mobility during lower greenschist to amphibolite facies metamorphism of a uniform turbidite suite (Greenland Group, New Zealand) has been evaluated using data for major elements and 19 trace elements. Simple comparison of average compositions at 2 wt % Al2O3 intervals in the data suites shows little contrast between lower greenschist protolith and upper greenschist and amphibolite facies equivalents, except for enrichment of CaO and Sr, and loss of Ba and Rb, particularly in the sandier end members. Division into psammitic and pelitic suites using TiO2/Al2O3 and Zr/Al2O3 ratios allows delineation of individual residual enrichment models on Ti-reference element plots, and both lithotypes can be used to assess potential elemental mobility. These plots show that a large number of elements (Ti, Al, Fe, Mg, Ce, Cr, Ga, La, Nb, Ni, Sc, Th, V, Zn and Zr) constitute immobile reference species, with abundances equal to their equivalent lithotype in the protolith, and little mass loss or residual enrichment. K and Rb also largely conform to the residual model, but in the amphibolite facies some exchange between pelite and psammite may occur. A number of elements show enrichment (Mn, Cu, Pb, U, Na, P) or depletion (Y) in a small number of samples, but the significance of these contrasts is questionable due to relatively large variation in the protolith. In contrast, Ca and Sr show progressive and marked enrichment with increasing grade, and Ba and As are clearly depleted in amphibolite facies psammites. In the amphibolite facies some Si may have been lost by psammites, and gained by the pelites, although there has been no mass change from the suite as a whole. A large part of the Ca and Sr enrichment in the amphibolite facies can be accounted for by metasomatic homogenization of calcareous concretions which occur in the lower grade protolith. The metamorphism of the Greenland Group is thus considered to be essentially isochemical.

Abstract:

In previous years of this project, we have developed the hypothesis that the high-pressure granulites exposed in the Moose Basin area of the Teton Range represent evidence of a 2.7 billion yearÂold continent-continent collision. We have described gneisses in the Teton Range that show two distinct metamorphic histories. In the northwest there are highÂpressure granulites suggesting metamorphism and deformation resulted from a 2685 to 2671 Ma Himalayan type orogeny (Frost et al., 2006). Gneiss exposed in the northwest is dominated by migmatites, with lesser kyanite bearing pelite, and some garnet amphibolite. Their ENd values at 2685 Ma are negative. Thermobarometric studies in the northwestern gneiss suggest burial of pelitic rocks to the base of continental crust, with pressures reaching 12 kilobars and temperatures of ~950Â° C during peak metamorphism (Fitz-Gerald, 2008). In modem plate tectonic environments these high pressures are associated with continent-continent collision. If the collisional hypothesis is correct, then this is the oldest documented example in the world.

Abstract:

The Thompson Nickel Belt is a ca. 35 km × 400 km northeast-trending segment of the northwest margin of the Archean Superior craton in Manitoba, bounded to the west by the Paleoproterozoic Reindeer Zone. The belt was metamorphosed and deformed during the Trans-Hudson orogeny (ca. 1.9–1.7 Ga). Mineral assemblages in metamorphosed pelite, aluminous greywacke, mafic igneous rock, iron formation, and ferruginous wacke define regional metamorphic domains, separated by mineral isograds, that are subparallel to the strike of the belt and to regional-scale D3 structures. An elongate, ca. 5 km × 73 km, central zone of middle amphibolite-facies rocks is characterized by the following: muscovite-bearing mineral assemblages in pelites containing combinations of staurolite, andalusite, and sillimanite; muscovite-free, staurolite + cordierite + garnet-bearing mineral assemblages in greywackes; hornblende-bearing mineral assemblages in mafic metaigneous rocks; and grunerite-bearing mineral assemblages in iron formation. Pressure–temperature (P–T) conditions of the middle amphibolite-facies zone are ca. 550–620 °C and 3.0–5.0 kbar (1 kbar = 100 MPa), with pressure increasing to the northeast. The middle amphibolite-facies zone is bordered to the east and west by an upper amphibolite-facies zone, ca. 5 km wide on the east and ca. 3–5 km on the west. The upper amphibolite-facies zone is characterized by variably migmatitic K-feldspar + sillimanite-bearing mineral assemblages in pelites; migmatitic, garnet + cordierite + sillimanite-bearing mineral assemblages in greywackes; orthopyroxene-free, hornblende-bearing mineral assemblages in mafic rocks; and orthopyroxene-bearing mineral assemblages in iron formations. Pressure–temperature conditions of the upper amphibolite-facies zone are ca. 640–710 °C and 3.0–5.5 kbar in the southeast, and 675–755 °C and 4.5–6.0 kbar in the northwest. The outermost metamorphic zone is of the granulite facies, characterized by migmatitic garnet + cordierite + K-feldspar-bearing assemblages in pelites and greywackes, orthopyroxene + clinopyroxene ± garnet-bearing mineral assemblages in mafic rocks, and orthopyroxene + K-feldspar-bearing mineral assemblages in iron formation in which biotite is unstable. Pressure–temperature conditions of the granulite-facies zone are ca. 775–830 °C and 5.0–7.0 kbar. The P–T paths in the Thompson Nickel Belt appear to be broadly clockwise, except for some domains where they are close to isobaric. The peak P–T conditions, combined with local but widespread development of andalusite, imply relatively steep geothermal gradients of ca. 33–51 °C/km during metamorphism. Regional bathozones (domains of uniform peak-metamorphic pressure) correspond in general but not in detail with the metamorphic-facies zones. They reveal an increase in pressure towards the northeast, suggesting greater degrees of postmetamorphic exhumation in that region. Microstructural analysis suggests that peak metamorphism coincided with, and possibly outlasted, the D2 deformation event. Metamorphic isograds were deformed by D3–D4 structures. These features are consistent with a tectonic model in which the Superior craton moved in a northwest or west-northwest direction relative to the Reindeer Zone, with greatest convergence and tectonic burial occurring at the Thompson promontory.

This study aimed to provide sonographic imaging of the patellar tendon (PT) – one of the main weight bearing structures for prosthetic use – in transtibial amputees. Thirteen males, who had been under follow-up for unilateral traumatic transtibial amputations, were enrolled. After physical examination of the limb, pain was evaluated by visual analogue scale and Leeds Assessment of Neuropathic Symptoms and Signs. Sonographic evaluations were performed by using a linear array probe (Aloka UST-5524-7.5 MHz) on both sides. Measurements pertaining to the contralateral limbs were taken as controls. In three subjects (23.1%), two with a silicone liner and one with a pelite liner, cortical irregularities were detected at the tibial insertion of the PT on the amputated sides. PTs were found to be thicker on the amputated sides when compared with those of the contralateral sides ( p = 0.03), and this increase in thickness correlated with disease duration ( r = 0.67, p = 0.01). Overall, our preliminary results imply that after transtibial amputation, PTs of the amputated sides tend to become thicker by time. These findings need to be complemented with future studies. In this regard, sonography seems to be promising for imaging the soft tissue problems of the stump.

Abstract:

Abstract The Cevennes area belongs to the para-autochthonous domain of the Hercynian Belt of the French Massif Central. Three lithological series, namely: sandstone-pelite, black micaschist and gneiss-micaschist, are identified. They form an imbrication of five tectonic units which overthrust the unmetamorphosed Viganais Paleozoic units to the south and the gneissic Mamejean Unit to the north. The structural, metamorphic and magmatic evolution of the Cevennes area is characterized by three events, namely: (1) southward shearing coeval to a MP/MT metamorphism dated around 340 Ma; (2) post nappe anatexis (T<750 degrees C, P>5 kb); (3) Namurian (ca 315 Ma) E-W extensional tectonics and plutonism. The structure of the Mt-Lozere-Borne granitic complex is constrained by new AMS and gravimetric data. The plutons are the driving power of the hydrothermal convective circulations responsible for an early deposition of diffuse arsenopyrite in the thermal aureole. Gold bearing sulfides are afterwards concentrated in quartz veins along brittle normal and wrench faults around the granite. Lastly, ore bearing quartz pebbles are sedimented in the Stephanian Ales coal basin.
