Abstract:
This detailed investigation was conducted for the South part of the Orikhovo-Pavlograd suture zone by using satellite imagery. At the first stage, the imagery was used to extract lineaments and arcuate relief elements. Further, geomorphological anomalies were highlighted by means of structural and geomorphological analysis of the study area. The significant number of ultrabasite bodies were distinguished alongside the entire Orikhovo-Pavlograd suture zone with allowance for the geological structure. The sites of kimberlite magmatism defined according to geophysical investigations can be associated with ultrabasite bodies. Prognostic sites of kimberlite magmatism were allocated and complex of morphostructural geoindication features were educed above the prognostic paleo-volcano that had erupted ultrabasites. The geoindicators of morphostructures are: the spreading and narrowing of a floodplain; displacement of a stream bed; deeping of the stream bed plunging depth; straightened reach of the stream bed; discordant course of the left tributaries of the Molochna river; augmentation of the stream bed meandering; floodplain marshy parts at the beginning of morphostructures; intense developing of a ravine-gully network on the right side of the Molochna river; localization of sand massifs on the anomalously located second terrace of the Molochna river flood-plain; rills and numerous artesian wells within the floodplain. These indicators have made it possible to construct a geoindication scheme, distinguish the prognostic Melitopol morphostructure and make a prognosis for mineral exploration. The formation of this morphological structure can be ascribed with a paleo-volcano, which igneous rocks are ultrabasites and kimberlites. Rocks of these complexes can be prospective evidence for diamond, iron, nickel, copper, lead and zinc deposits exploration. Hydrothermal and metasomatic sulphide (polymetallic) mineral occurrences can be explored as well. The procedure of geoindication investigation will be applied for integrated exploration throughout the entire area of the Orekhovo-Pavlograd suture zone.

Abstract:
Relevance of the work is due to the need to establish structural control of the mineralization of jewelry demantoid in ultrabasites of the Korkodinsky massif for forecasting, prospecting and exploration of its deposits. Purpose of the work: identification the criteria for structural control at the Poldnevsky demantoid field. Research methodology: analysis of literature data on research topics, studying the geology of the field and the nature of the distribution of mineralization, the conditions of occurrence of mineralized zones, the features of fault tectonics in the quarry of the Poldnevskoye field, the study of thin sections and thin sections by optical methods Results. A geotectonic model for the formation of the Korkodinsky ultrabasite massif represented by a crust-mantle mixture from the depth of 50–60 km is proposed. In the process of rock hoisting, decompression, metamorphism and hydrothermal-metasomatic transformations, decompression fracturing were experienced. The earliest fractures were made by hydrothermal-metasomatic clinopyroxenite, which then also underwent decompression fracturing. Ultrabasic rocks and clinopyroxenites underwent local antigoritization. Later decompression fractures are made by antigorite, clinochrysotile, carbonate, sometimes magnetite and demantoid. All of them were formed under conditions of continuous decrease in allround pressure and synchronous opening of decompression fractures. The largest fractures are oriented subparallel to the wings of the enclosing fault and have a steep fall. The fractures are sinuous and can be arranged en echelon. Mineral-forming fluids were released from the massif as a result of decompression and mixed with meteoric waters penetrating along tensile cracks in the roof of the massif. Late low-temperature serpentinization of the massif is accompanied by the manifestation of “serpentinite tectonics”, which can destroy bunches with demantoid mineralization when superimposition. The demantoid mineralization in weakly serpentinized dunites is preserved from destruction by “serpentinite tectonics”. Conclusion. Since demantoid mineralization is confined to decompression fractures, the possibilities of structural control are very limited. The largest fractures are oriented subconcordantly to the sides of the fault enclosing the massif. This pattern of the distribution of demantoid mineralization in ultrabasites is favorable for the formation of deluvial-alluvial placers, but is unfavorable for development in bedrock depth.

Abstract:
Abstract Massive chromitite, banded chromitite and disseminated chromite grains are found in a ˜3800 Ma layered ultrabasic body in West Greenland. The major part of the ultrabasite is dominated by dunite. In the upper exposed part, harzburgite and sheets of gabbro-anorthosite occur. Chromite grains in dunites, and in massive and banded chromitites are homogeneous, with increasing Fe contents upwards in the intrusion. In harzburgites chromites show unusual and very complex textural relationships, with two generations ofchromites one replacing the other, and both exhibiting exsolution textures. In harzburgites, an Fe-rich chromite crystallized first. This first chromite exsolved two spinel phases in a very fine-scale pattern and ilmenite lamellae in a trellis pattern. The Fe-rich chromite was later partly replaced by Al-rich chromite, which crystallized contemporaneously with formation of a late gabbro-anorthositic melt. Subsequently, the Al-rich chromite exsolved a very fine-scale magnetite-rich phase. The exsolutions in the first generation chromite were formed under magmatic conditions. Exsolution of ilmenite lamellae in Fe-rich spinel was caused by oxidation under magmatic conditions.

Abstract:
A new formation model of the global Atlantic-Arctic heterochronous rifting system is substantiated, according to which the Central and North Atlantics, Labrador-Baffin seas, and Arctic Ocean represent morpho-tectonic elements of different orders of the united recent Atlantic-Arctic Ocean. Evolution of the global rift system of this ocean includes three stages: the first stage (D–J1) was expressed by establishment of a tectonic zone in the lithosphere of Pangea with formation of the ophiolite ultrabasite-gabbro association; the second stage (J1–₽1) represented stretching of the continental crust to form depressions and uplifts with areal manifestation of trap magmatism of Cretaceous and other ages; and the third one (₽2–present) is neotectonic-magmatic reactivation with formation of a middle ridge, that is being accompanied by outpouring of glassy basalts and by hydrothermal manifestations. Within the framework of this model, the history of formation is reconstructed of the Eurasian Basin and the Gakkel Ridge, that were included in the Russia's updated application for expansion of the outer continental shelf border.

Abstract:
The petrography and mineralogy of Iherzolite nodules from an intrusive body of alkaline-ultrabasic rocks on Jetty Peninsula. The nodules are massive with a porphyritic hypidiomorphic granular texture. The main rock-forming minerals are: olivine, pyroxene, garnet and chrome spinel. The nodules are coarse granular spinel-garnet Iherzolites that are chemically similar to pyrope peridotite from Krezemze, Czechoslovakia, and pyrope-bearing peridotite from alkaline ultrabasites of Yakutia, USSR. The Al2O3 content in enstaties and Ca/(Ca + Mg) ratio in co-existing chrome diopside suggest that equilibrium conditions of the mantle mineral assemblage are: T = 875–900°C, P = 20–24 kbar, conditions typical of the spinel-pyrope facies of the upper mantle. Depths of withdrawal of the inclusions do not exceed 60–75 km. Available age determinations of the intrusive alkaline-ultrabasic rocks (145–150 Ma) suggest that alkaline-ultrabasic magmatism and withdrawal of plutonic nodules were related to rifting which resulted in the breakup of the Gondwana supercontinent in the late Mesozoic.

Abstract:
This work is concerned with the lower part of the Eastern Layered Series (LELS) of Rhum, and with the marginal relationships of the ultrabasic complex in eastern Rhum. The Lower Eastern Layered Series comprises approximately Units 1-5 of previous workers. Remapping has revealed considerable along-strike lithological variation in the units of the L.E.L.S. It is suggested, on the basis of field and geochemical evidence, that two layers formerly regarded as 'conformable intrusive sheets of fine grained olivine gabbro' may be evolved allivalite layers rather than later intrusions. Xenolith suites in these layers and elsewhere, indicate a component derived from the roof or walls of the magma chamber. Cryptic variation is more extensive in the L.E.L.S. than in other parts of Rhum: olivine forsterite content varies from 85.6 to 70, and clinopyroxene MgX100/(Mg+Fe) varies from 88 to 74. Post-cumulus effects and sub-solidus re-equilibration have altered the initial compositions of the mineral phases. The migration of interstitial liquids has had a major effect on mineral chemistry. Replacement of plagioclase-rich rocks by peridotite is a significant process in parts of the sequence. This is ascribed to disequilibrium between migrating pore liquids and plagioclase. The data are consistent with a model of repeated replenishment by picritic magma, although the replenishing liquids may have been slightly less magnesian than those subsequently available during the formation of the upper ELS. Re-examination of the eastern margin of the ultrabasic complex suggests that the ultrabasic rocks formed more or less in situ, and that fragments of the roof to the intrusion occur in places. Locally under these roof fragments variolitic olivine-rich gabbros are developed, which may represent the chilled margin to the ultrabasic complex.

Full text
Abstract:
L'ophiolite d'Oman est un fragment de la lithosphère océanique téthysienne obducté sur la marge arabe au crétacé supérieur. Elle occupe un domaine de la chaîne alpine où la convergence entre l'Arabie et l'Eurasie n'a pas encore atteint le stade de la collision continentale. Affleurant de façon, presque continue sur une longueur de 475 Kilomètres parallèlement à l'axe de la paléo- dorsale, c'est le plus grand segment de lithosphère océanique accessible à l'étude directe. La section mantellaire constitue 60% de la surface d'affleurement de l'ophiolite (30.000 Kilomètres carrées). Cette thèse est consacrée à la cartographie des structures internes de cette unité. Les structures crustales permettant d'établir une référentielle paléo-tectonique (paléo-horizontale, azimut et flanc de la paléo-dorsale) furent également relevées. Divers arguments pétrologiques et structuraux permettent d'apparenter l'ophiolite d'Oman aux dorsales rapides actuelles. Les péridotites mantellaires, de composition harzburgitique à dunitique, gardent l'empreinte de deux déformations plastiques successives, la première associée à la formation de la lithosphère (flux asthénosphérique), la seconde au charriage intra-océanique qui préluda à son obduction. La géométrie de l'écoulement asthénosphérique et la composition de la section mantellaire présentent de fortes variations longitudinales. La formation de la lithosphère océanique, au droit des dorsales rapides, implique l'ascension de diapirs asthénosphériques espacés de quelques dizaines à plus de cent Kilomètres les uns des autres. Siège d'une activité magmatique exceptionnelle, ces diapirs semblent également jouer le rôle de centres d'alimentation privilégiés de la chambre magmatique sus-jacente. Un de ces diapirs, figé et échantillonné lors du charriage à la dorsale, a pu être cartographié en détail (région de Maqsad) : le lux asthénosphérique, vertical dans un conduit de 10 à 20 Kilomètres de diamètre, se brise sous le plancher de la chambre magmatique dans une zone de transition épaisse seulement de quelques centaines de mètres et est ensuite canalisé parallèlement à l'axe de la dorsale sur une distance d'au moins 30 Kilomètres depuis le centre du conduit. Cette géométrie implique une modification brutale de la rhéologie mantellaire dans la zone de transition attribuée à une augmentation catastrophique du rapport magma/roche. Un modèle physique de circulation, asthénosphérique a été construit en introduisant une discontinuité de viscosité de plusieurs ordres de grandeur au sommet du diapir. Une telle condition permet, en effet, de canaliser un pourcentage important du flux dans un étroit créneau superficiel. La pression dans le diapir est discontinue sur une épaisseur d'une centaine de mètres sous l'interface pour pouvoir vaincre la surpression due au fluage plastique et continuer son ascension vers la surface. Loin des diapirs, le flux mantellaire peut être régulier à l'échelle de la centaine de kilomètres ; il est alors sub-parallèle au Moho et perpendiculaire à l'axe de la dorsale, évoquant l'accrétion de la lithosphère en régime d'expansion stationnaire. L'angle d'une dizaine de degrés entre le Moho et le plan de fluage reflète probablement la pente moyenne des isothermes au niveau de la zone d'accrétion (flanc de la dorsale). La déformation associée au charriage intra-océanique (CIO) affecte les périodiques sur une épaisseur de quelques centaines de mètres au-dessus du plan de charriage basal, lui-même situé à une profondeur maximale de neuf kilomètres sous le paléo-Moho. Elle peut affecter également des niveaux plus élevés de la section mantellaire et la section crustale sous forme de bandes de cisaillement mylonitiques verticales pouvant atteindre 2 kilomètres d'épaisseur. Ces cisaillements sont contemporains de l'intrusion de magmas hydratés au sein de la section mantellaire, peut-être à mettre en relation avec le volcanisme différencié (" volcanisme 2 ") coiffant l'Ophiolite. Le CIO s'accompagne localement de la fusion de la semelle. Lors de l'initiation du CIO, la lithosphère présentait un fort gradient thermique vertical. D'un point de vue cinématique, la déformation enregistrée par la semelle, les péridotites basales et les bandes de cisaillement sont en concordance parfaite. Le CIO s'accompagne de déplacements considérables de la lithosphère charriante parallèlement à l'axe de la dorsale (de l'ordre de la centaine de kilomètres). L'initiation du CIO à la dorsale elle-même rend le mieux compte de ces observations. Le charriage à la dorsale implique l'inversion rapide (1 à 2 millions d'années) du régime d'expansion en régime compressif. On l'explique par un blocage momentané de la subduction de la Téthys sous l'Eurasie causée par des collisions entre des microcontinents, des arcs insulaires et la marge active eurasienne survenues à cette époque (Albien supérieur). De manière générale, les événements enregistrés par l'Ophiolite d'Oman s'intègrent bien dans l'évolution cinématique et géologique du domaine téthysien.

Abstract:
Country rocks surrounding the Rhum Tertiary ultrabasic complex have experienced severe thermal metamorphism, partial melting and mobilization resulting in the formation of extensive areas of intrusion breccia. Evidence from several sources indicates a maximum temperature in the country rocks of 960 ± 40°C. Contrary to previous suggestions the complex was not emplaced as a fault block enclosed by a "Marginal Gabbro", but formed in situ at a depth of less than 1Km. Large-scale layering continues to within 2m of the country rocks, and shows no change in either thickness or orientation close to the contact. Smallscale layers at Harris Bay thin and terminate towards the contact with the Western Granophyre. Strontium isotope data showsthat the margins of the complex have experienced considerable crustal contamination. Contamination may have taken place by mixing of anatectic country rock melt with the resident basaltic liquid during boundary flow. Whole-rock and isotope geochemistry suggests that marginal microgranodiorite ("hybrid rocks") formed during a process of combined assimilation and fractional crystallization. Lead isotope data indicate that rocks of the ultrabasic complex, as well as earlier Tertiary granophres and felsites, were contaminated with Lewisian lead. The crustal level at which this took place and the processes involved remain unclear. Oxygen isotope analyses show that rocks of the contact zone have undergone large-scale exchange with heated, meteoric fluids. In response to inflation of the complex the country rocks experienced considerable deformation, and in places the chamber roof underwent gravity collapse. Deformation resulted in increased country rock permeability, thus enhancing hydrothermal circulation and promoting high-cooling rates along the contact zone. A consequence of this process is the local preservation of quenched ultrabasic material at Harris Bay, and the ubiquitous development of rapid growth textures in all lithologies within the contact zone.

Full text
Abstract:
The ultrabasic rocks studied in this thesis are located in the Upper Allochthonous Thrust Complex nappes of the Braganca and Morais massifs, Träs-os-Montes, N. Portugal. They are relicts of residual mantle and cumulates formed at a destructive continental margin. In the Braganca massif, the ultrabasic rocks consist mainly of a harzburgite formation, which is residual mantle. This formation contains lenses of a separate chromitite-bearing dunite formation. The Morais massif assemblage, at an equivalent structural level, is made up of peridotite and gabbroic/troctolitic cumulates. The chromitite-bearing dunite formation crystallised within small magmatic masses. This chromite crystallisation acted to fractionate the associated Platinum-Group Element (PGE) assemblage. Os, Ir and Ru were incorporated as laurite and irarsite minerals during chromite grain crystallisation, and are located in textural positions from the centres to the margins of the chromite grains. In contrast Pt-bearing arsenides and sulpharsenides started crystallising after the Os, Ir, Ru group, and are only located at the margins of or in between chromite grains. More fractionated assemblages show positive slopes on chondrite normalised whole rock PGE plots. Pd is not directly associated with this fractionation. Instead its mineralisation is associated with that of the base-metal sulphide. Serpentinisation has caused recrystallisation of much original pentlandite to heazlewoodite and magnetite. At the same time Pd-bearing alloys were created, mostly adjacent to sulphide grains with the source of the Pd being in solid solution within the base-metal sulphide. Several factors suggest that the chromite mineralisation was derived from melts of boninitic affinity. The relatively high Pd/Cu ratios calculated for a silicate melt from which the chromite crystallised are consistent with this. The composition of the chromite grains, having 1000r/(Cr+Al) ratios clustering around 75, is typical of boninitic magmas. In addition the refractory composition of the harzburgite formation, and the high tenors of Pd within sulphide, show that it was a possible source for such boninitic melts. The chromite mineralisation took place down to depths of 30km within the mantle wedge of a destructive continental margin.
