Abstract The plate interface undergoes two transitions between seismogenic depths and subarc depths. A brittle-ductile transition at 20–50 km depth is followed by a transition to full viscous coupling to the overlying mantle wedge at ∼80 km depth. We review evidence for both transitions, focusing on heat-flow and seismic-attenuation constraints on the deeper transition. The intervening ductile shear zone likely weakens considerably as temperature increases, such that its rheology exerts a stronger control on subduction-zone thermal structure than does frictional shear heating. We evaluate its role through analytic approximations and two-dimensional finite-element models for both idealized subduction geometries and those resembling real subduction zones. We show that a temperature-buffering process exists in the shear zone that results in temperatures being tightly controlled by the rheological strength of that shear zone’s material for a wide range of shear-heating behaviors of the shallower brittle region. Higher temperatures result in weaker shear zones and hence less heat generation, so temperatures stop increasing and shear zones stop weakening. The net result for many rheologies are temperatures limited to ≤350–420 °C along the plate interface below the cold forearc of most subduction zones until the hot coupled mantle is approached. Very young incoming plates are the exception. This rheological buffering desensitizes subduction-zone thermal structure to many parameters and may help explain the global constancy of the 80 km coupling limit. We recalculate water fluxes to the forearc wedge and deep mantle and find that shear heating has little effect on global water circulation.

Transition zones in railway tracks are the locations with considerable changes in the vertical support structures. Due to the differential stiffness and settlement in the open track and the engineering structure resulting in the dynamic amplification of the wheel forces, track settlement is usually observed in the approaching zones. The settlement in transition zones is detrimental to the track components and passenger comfort. This paper presents the results of the experimental analysis performed in three transition zones which were in various conditions. The dynamic displacements of rails due to passing trains were measured at multiple points (dynamic profile) in the approaching zones. The device employed is a contactless mobile device for measuring displacements, which is based on the digital image correlation technique. Because the operational parameters of the digital image correlation-based devices are important for measurement accuracy, prior to the in situ measurements, this device was tested in a laboratory to study the influence of the operational parameters, including the elevation/heading angles, the focal length of the cameras, and the measuring distance. After determining the optimal operational parameters for the railway field, multiple-point measurements were performed in the transition zones. The length of the approaching zone was studied first. Also, the dynamic profiles of the embankment–bridge and bridge–embankment transitions were analysed. Finally, by comparing the multiple-point displacements in the approaching zones in different conditions, it was found that the dynamic profile of the rail displacements has a good correlation with the track condition in the transition zone. The results are presented and discussed.

Biogeographical transition zones are areas of a complex biotic mixture located at the borders between biogeographical units. Climatic, physical and ecological factors should play an important role in allowing coexistence of different biotic elements in the transition zone. Here, we explore the relationship between environmental factors and biogeographical transition zones, defined by Neotropical mammal distributions, by a model selection approach based on the Akaike information criterion and accounting for the spatial structure in the data. We detected three areas of high overlap between mammalian areas of endemism. Two of them corresponded to the well-established regional-level transition zones, namely Mexican (MTZ) and South American (SATZ) transition zones; the third was one located in south-eastern Brazil, approximately between the Paraná and Chacoan dominion that we call The Atlantic Forest integration zone (AF). Only one explicative variable was shared by the three transitions zones (precipitation of the warmest quarter). However, shared variables with great explanatory power indicated two environmental aspects as facilitators for the coexistence of different biotic components in a given geographical area. The first one was the heterogeneity component, either topographic for the SATZ and MTZ or climatic for the AF. The second one was related non-extreme thermal conditions: precipitation of the warmest quarter, interpreted as a thermal buffer, shared by AF and SATZ, and isothermality shared by MTZ and SATZ.

Transition zones in railway tracks are of importance for infrastructure managers, due to the high maintenance required to maintain appropriate track geometry. To improve our understanding of the performance of transition zones, a research program was conducted in The Netherlands, in which a transition zone was extensively monitored during regular train traffic. This paper presents some of the results from the monitoring of this transition zone. The results highlight the poor performance of this transition zone compared to its expected design performance. The track was found to be hanging over the transition zone, exhibiting a rocking motion about a culvert. Track stiffness was found to reduce linearly with increasing train speed. The implications on the design of transition zones are discussed, with recommendations made.

Abstract Transition zones are problematic in biogeographical classification as they represent artificial biotic areas. A review of transition zones into existing biogeographical classifications shows conflicting area taxonomies. While many authors consider transition zones as overlap zones or areas of biotic mixing, only a few have considered excluding them from biogeographical classification all together. One way of incorporating transition zones into a natural classification is by treating them as artefacts of geographically overlapping temporally disjunct biotic areas. In doing so, geographically overlapping biotic areas may occupy the same space but have different boundaries and histories. Temporally disjunct areas do form natural hierarchical classifications, as seen in the paleobiogeographical literature. A revision of each transition zone will determine whether they are artificial areas, areas within their own right or potentially geographically overlapping temporally disjunct regions.

AbstractA Bi-Ni-Co vein in the contact zone of a granite near Pozoblanco, Córdoba, Spain, shows a zoned structure with mm-thin quartz wall zones, up to 20 cm thick Bi-rich quartz zones, and a few cm thick quartz-bismuth transition zones grading into a central quartz vug zone. The Bi-rich zones show textures indicating a metacolloidal origin from a silica gel enriched in adsorbed Bi: (1) globular and chain aggregates of fine-granular allotriomorphic quartz represent morphological relics of a globulated silica gel; (2) quartz rosettes, chain rosettes and stringer-combs radiating from the quartz globules and chains represent crystallised silica gel matrix; (3) crack fillings of quartz, gersdorffite and platy bismuth dendrites represent precipitates of metal-saturated dilute hydrosols filling shrinkage cracks in the desiccating and crystallising gel; (4) quartz spherocrystals in rosettes and combs are clouded with colloidal particles inherited from the silica gel; (5) unsupported wall rock inclusions represent inclusions in a viscous silica gel precursor covering fissure walls. The thin wall zones are quartz fillings of cracks between shrinking gel and walls. The transition and vug zones are recrystallised colloidal silica crusts precipitated by fissure-filling rest-solutions. Tree-like bismuth-gersdorffite dendrites in the transition zones are precipitates of metal-rich solutions infiltrating from the Bi-rich zones into the recrystallising silica crusts. The pre-concentration of metals in silica gels explains the dendrite formation without assuming abnormally high metal concentrations in transporting solutions or long range diffusion processes.

This research investigates soil recovery following landslides at the Whatawhata Research Station 20 km west of Hamilton. Six landslides were studied, ranging in age from pre-1953 to 2014. The landslides were divided into four zones: shear zones (mean of 25% of landslide area), intact accumulation zones (20%), transition zones (40%), and re-deposition zones (15%), along with a control. Soils were well-developed in the control and intact accumulation zones and least recovered in the shear and re-deposition zones. Mean A horizon depths ranged from 2 cm in the shear and re-deposition zones to 7 cm in the transition zone, 17 cm in the intact accumulation zone, and 20 cm in the control. Mean soil carbon contents were lower (P

Channel-lobe transition zones (CLTZs) represent critical areas between the submarine slope and basin floor systems, where sediment gravity flows transition from confined to unconfined. In modern systems, this area is characterised by a distinctive assemblage of erosional and depositional features. However, the transfer of the CLTZ into the stratigraphic record is not well constrained. By the detailed study of various well-constrained exhumed base-of-slope systems within the Tanqua and Laingsburg depocentres of the Karoo Basin, South Africa, the sedimentary and stratigraphic record of CLTZs is investigated. The first detailed study of key depositional and erosional bedforms that characterise ancient CLTZs, including sediment waves and giant scour-fills, are presented. Their process record suggests complicated flow-bedform interactions, where both the preservation and sedimentary characteristics are dependent on the evolution of the feeder channel and the lateral position to the channel-mouth. Within the base-of-slope environments, juxtaposition of lobes and channel-fills is common. The lobes in these proximal fan environments are sandstone-prone and differ in facies and architectural characteristics to lobes downdip on the basin floor. The sand-rich nature and juxtaposition of elements in ancient CLTZs means that they are considered attractive hydrocarbon reservoir targets in the subsurface. However, fine-scale reservoir modelling and streamline simulations suggests that the relatively limited sand-volume of channel-fills in comparison to lobe deposits in these environments can have a negative impact on reservoir performance due to its effect on reservoir connectivity. Overall, the stratigraphic record of CLTZs shows high diversity in architecture, facies characteristics and volume, which can be related to three primary controls: a) spatial variability, b) flow efficiency and c) channel evolution. These three controls infer that CTLZs are highly dynamic, migrating and changing in dimensions over time; this needs to be considered when assessing how CLTZs are recorded in the rock record.

Track deterioration has a serious influence on the safety and efficiency (speed restriction) of train operations. Many expensive, disruptive and frequent repair operations are often required to maintain the ballast characteristics due to the problem of settlement. Because of this, a geogrid solution that has proved to be a simple and economical method of reinforcing track ballast is widely used. This project presents an evaluation of the behaviour of geogrid-reinforced railway ballast. Experimental large box pull-out tests were conducted to examine the key parameters influencing the interaction between ballast and the geogrid. The experimental results demonstrated that the triaxial geogrid with triangular apertures outperforms the biaxial geogrid with square apertures and the geogrid aperture size is more influential than rib profile and junction profile. The discrete element method (DEM) has then been used to model the interaction between ballast and geogrid by simulating large box pull-out tests and comparing with experimental results. The DEM simulation results have been shown to provide good predictions of the pull-out resistance and reveal the distribution of contact forces in the geogrid-reinforced ballast system. The discrete element method has also been used to simulate cyclic loading of geogrid-reinforced ballast under confined and unconfined conditions. For the confined condition, box tests have been simulated on unreinforced samples and reinforced samples with different geogrid positions and geogrid apertures. The response of the ballast layer reinforced with geogrid under repeated loading agrees with experimental results. It was found that the optimum location of geogrid is 100 mm depth from base, and the triaxial geogrid outperforms biaxial geogrid. For the unconfined condition, cyclic loading of a trough of ballast has also been simulated, and the sample with the geogrid at 50mm from the sub-ballast layer performs best. It was also found that the used of two geogrids at both 50mm and 150mm from the sub-ballast gave a smaller settlement than using a single layer geogrid, or the unreinforced ballast. The geogrid reinforcement limits the lateral displacement in reinforced zone, which is approximately 50mm above and below the geogrid. Previous investigations have shown that the abrupt stiffness change in track support is often associated with accelerated rates of deterioration of track geometry, high maintenance demand, and poor ride quality. However, at present, there is no detailed understanding of the mechanisms of track geometry deterioration at transition zones. This work provides insight into the factors that can cause or accelerate track degradation at the transition zones, in order to identify and evaluate appropriate mitigation design. A simple track transition model with dimensions 2.1m x 0.3m x 0.45m was simulated by using PFC3D. In order to identify and evaluate appropriate mitigation methods, two kinds of transition patterns, including a single step change and a multi step-by-step change for subgrade stiffness distribution were tested. The influence of the train direction of travel and speed on the transition were also investigated. In addition, geogrid was used in the ballast layer to examine the effects of geogrid reinforcement.

Les failles importantes en coulissage orientées NS comme la faille du Zendan-Minab-Palami (ZMP) et la faille de Borazjan-Kazerun-Dena séparent des styles différents de déformation au sud de l'Iran. Le ZMP sépare la zone de collision du Zagros à la zone de subduction du Makran. Nous utilisons des données microsismiques et téléséismiques enregistrées par un réseau temporaire de 50 stations qui a fonctionné en novembre et décembre 1999. La microsismicité observée dans cette région montre une activité diffuse entre la faille de Zendan-Minab-Palami et la faille de Jiroft, limitée par la dépression du Jaz-Murian. La distribution de la sismicité en profondeur montre que nos données sont localisées entre 15-35 km, plus profond que dans le Zagros et avec une augmentation des profondeurs vers le NE. L'analyse des mécanismes au foyer montre des mécanismes en coulissage dextre et des mécanismes en chevauchement de pendage faible distribués en profondeur. L'inversion des résidus des séismes locaux montre une anomalie de vitesse plongeant vers le N associée aux séismes. La tomographie téléséismique confirme une variation importante de la structure au passage de la faille zone de Zendan-Minab-Palami, rapide sous le Zagros, lente à proximité du ZMP, qui affecte toute la croûte et le manteau supérieur. L'analyse des fonctions récepteurs montre une structure complexe sous la zone de faille de Zendan-Minab-Palami avec des conversions dans la croûte supérieure à 15 km . En revanche l'interface observée pour la région du Makran se situe à 35 km profondeur. Un réseau temporaire de 29 stations sismologiques a fonctionné en avril et juin 2002 dans la région de Borujen située dans le Zagros nord , au nord du système Qatar-Kazerun. La distribution de la sismicité dans cette région est diffuse et suit approximativement la direction des structures tectoniques, la faille de Dena, d'Ardal (MRF) et le HZF. En revanche le MZT (Main Zagros Thrust) n'est pas sismiquement actif. La sismicité est localisée entre 2-16 km de profondeur et montre des alignements verticaux à proximité de la faille d'Ardal et la faille de Dena. L'analyse des mécanismes au foyer montre des mécanismes en décrochement et des mécanismes en chevauchement. L'étude de la structure de la croûte en utilisant la méthode des fonctions récepteurs montre une conversion claire à 60 km de profondeur sans aucune variation importante au passage de la faille de Dena.

De nombreuses familles de polluants organiques en provenance de différentes sources se retrouvent dans les milieux aquatiques continentaux et littoraux. Ces molécules, dont les lipophiles et les persistantes, sont souvent présentes à l'état de trace dans la fraction dissoute. L'utilisation de compartiments concentrateurs comme les sédiments rend alors plus accessible l'évaluation des concentrations ambiantes du milieu. L'objectif de la thèse a été d'évaluer l'exposition en zones côtières aux différentes familles de contaminants organiques « émergents » incluant les filtres UV, les alkylphénols et les alkylphénols polyéthoxylés, ainsi que « persistants-classiques » incluant les hydrocarbures aromatiques polycycliques et les polychlorobiphényles dans les sédiments et, éventuellement, dans les eaux. Un important effort de recherche a été accordé à l'étude des variations spatiales et temporelles des contaminants sélectionnés dans les sédiments, permettant ainsi l'acquisition d'un premier jeu de données nationales (libanais) représentatif pour ces familles de contaminants.Trois rivières en Méditerranée orientale et leur environnement côtier ont été pris comme cas d'étude en plus de la côte d'une petite ville et ses sites portuaires qui ont été sélectionnés afin de compléter l'étude en milieu côtier. Un premier aperçu des niveaux de ces contaminants hydrophobes dans les zones côtières recevant des apports typiques de la Méditerranée orientale est ainsi fourni. Les résultats des analyses chimiques ont clairement montré l'impact des rejets des effluents non traités dans les zones côtières via les entrées des rivières et les déversements directs le long de la côte, en absence des activités récréatives (pour les filtres UV) et de rejets industriels (pour les alkylphénols et les alkylphénols polyéthoxylés). Les zones de transition peuvent être à l'origine de la contamination de l'environnement côtier des trois rivières par ces polluants émergents en absence des apports marins. Des concentrations élevées en hydrocarbures aromatiques polycycliques et en polychlorobiphényles ont été mesurées dans les sédiments prélevés en milieu côtier. Cette contamination a persisté des années après la marée noire qui a envahi la côte Est-Méditerranéenne en 2006. Nos résultats globaux indiquent que les concentrations mesurées dans les sédiments des trois rivières étudiées et du littoral peuvent être classées parmi les niveaux les plus élevés détectés dans le pourtour du bassin méditerranéen et pouvant induire des effets toxiques chez le biota aquatique.Ce travail peut être d'une importance primordiale pour la région Est-Méditerranéenne, et plus particulièrement pour le Liban, un pays qui, malgré d'être parmi les signataires de la convention de Barcelone pour la protection de la mer Méditerranée et qui est, par la suite, impliqué dans la surveillance de la qualité de son milieu marin, souffre jusqu'à présent des rejets de différents types d'effluents non traités le long de ces côtes en absence des stations d'épuration
Many organic pollutants issued from different sources are present into freshwater and coastal waters. Since these lipophilic contaminants are present at trace levels in water, accumulator compartments such as sediments can be used to assess their concentration in aquatic systems. The objective of the thesis was to assess the exposure in coastal areas to the various families of organic contaminants namely "emerging pollutants" including UV filters, alkylphenols, alkylphenol polyethoxylates, and "persistent pollutants" including polycyclic aromatic hydrocarbons and polychlorinated biphenyls in sediments and water. A major research effort has been given to the investigation spatial and temporal dynamics of the selected pollutants in sediment, allowing the acquisition of a first set of national data (Lebanese).Three rivers and their coastal environment in the eastern Mediterranean have been taken as a case study in addition to the small coastal city that was selected to complete the study in the coastal environment. A first overview of the levels of these hydrophobic contaminants in coastal areas receiving typical eastern Mediterranean inputs is thus provided. The results of chemical analyzes have clearly shown the impact of discharges of untreated effluents into coastal areas via inputs from rivers and direct discharges along the coast, without recreational activities (for UV filters) and industrial effluents discharges (for alkylphenols and alkylphenol polyethoxylates). Transition zones may act like a source of contamination of the three rivers coastal environment in the absence of marine inputs. Elevated concentrations of polycyclic aromatic hydrocarbons and polychlorinated biphenyls were measured in sediments in coastal environments. This contamination has persisted for years after the oil spill that has invaded the Mediterranean coast in 2006. Our overall results indicate that concentrations in sediments of the three studied rivers and the coastline can be classified among the highest levels detected in the Mediterranean basin and may induce toxic effects in aquatic biota.This work may be of paramount importance for the East-Mediterranean region, and particularly for Lebanon, a country which, despite being a signatory to the Barcelona Convention for the Protection of the Mediterranean Sea and is, subsequently involved in monitoring the quality of its marine environment, suffers far different types of discharges of untreated effluent along its coast in the absence of wastewater treatment plants

To support the transition towards a low-carbon economy, mining companies, international financial institutions and governments are preparing to drastically scale up mineral extraction of energy transition minerals such as cobalt and lithium. Mineral extraction, however, has far-reaching impacts on the biophysical environment and mining-affected communities that may become more severe under a changing climate. In May 2019, the World Bank sought to respond to these challenges with the launch of its climate-smart mining Facility, evoking critique from non-governmental organisations working in solidarity with frontline communities. Drawing on poststructuralist political ecology and discourse analysis, this study examines the conflicting narratives on mining for the energy transition and interrogates the political solutions made conceivable through these narratives. Utilizing documents by proponents and opponents of the climate-smart mining Facility, and semi-structured interviews, the analysis reveals two contrasting discourses on mining for the energy transition, problematising climate change as a problem of rising CO2 emissions, and as a social justice problem rooted in global inequality respectively. These distinct conceptualisations generate three key and overlapping tensions, relating to (i) global versus local priorities, (ii) mitigation and adaptation, and (iii) socio-technical versus socio-political transformations. By highlighting these discursive processes, the results aid our understanding in how mining is made salient in the carbon constrained future, and which actors are likely to benefit and be harmed by the promotion of climate-smart mining.

AbstractThe maintenance of soil productivity is important for sustained crop yield in low-input systems in the tropics. This study investigated the impact of four different land use types, namely, maize and cassava cropping, woodlot/plantations, and natural forests on soil productivity components, especially soil carbon accretion, at six sites within two agro-ecological zones of southern Ghana. Soil properties were significantly different between sites and ecological zones. The coastal savanna zones, which is a low rainfall zone had relatively lower soil carbon storage than the high rainfall forest-savanna transition zone. Soil productivity conditions in the later zone were much more favorable for cropping than the former. Land use types significantly affected the soil carbon (SOC) storage within the two ecological zones. In the low rainfall zone, soil carbon accretion by maize cropping, cassava cropping, and plantations were 48%, 54%, and 60%, respectively, of the forest carbon stock (47,617 kg/ha). In the transition zone, the soil carbon accretion was over 90% of the forest value (48,216 kg/ha) for all land use types. In effect use of land use types in maintaining soil productivity must consider the conditions in a given ecological zone.

The expansion of smallholder farms into larger farm sizes is a key strategy for growing agriculture in sub-Saharan Africa. This strategy could simultaneously expand farm incomes while addressing poverty since the majority of farms in sub-Saharan Africa are smallholder farms. There is limited existing research on the possible role of conflicts in stymying the ability of smallholder farmers to transition into larger-scale farming and on the impacts of conflicts in areas that are not directly within active conflict zones. In this paper, we investigate the impacts of conflict on the ability of smallholder farmers to transition to larger scales in two regions that are not in a traditional conflict zone, by developing a household utility maximisation model to explain choices made by farm households in response to conflict.
