Résumé :
AbstractIndian basement faults, which bound three orogen-perpendicular palaeotopographic ridges of Precambrian Indian basement south of the Himalaya, extend to the base of the Indian lithosphere and to the northern extent of the Indian lithosphere underneath Tibet. In the eastern Himalaya, the active orogen-perpendicular Yadong–Gulu graben is aligned with an earthquake-generating strike-slip fault in the high Himalaya. We argue that the graben results from crustal necking during reactivation of the underplated basement fault. In the central Himalaya, along-strike diachronous deformation and metamorphism within the Himalayan metamorphic core, as well as lateral ramps in the foreland thrust belt, spatially correspond to the Lucknow and Pokhara lineaments that bound the subsurface Faizabad Ridge in the Indian basement. Analogue centrifuge modelling confirms that offset along such deep-seated basement faults can affect the location, orientation and type of structures developed at various stages of orogenesis and suggests that it is mechanically feasible for strain to propagate through a melt-weakened mid-crust. We suggest that inherited Indian basement faults affect the ramp-flat geometry of the basal Main Himalayan Thrust, partition the Himalayan range into distinct zones, localize east–west extension resulting in the Tibetan graben and, ultimately, contribute to lateral variability in tectonic evolution along the orogen's strike.

The presence of dominantly dykes, dyke swarms and sills along with the basement rocks indicate that the study area has undergone deep erosion exposing the basement rocks and these magmatic bodies (dykes, dyke swarms and sills) actually represent the plumbing system for the mantle derived melts, which contributed significantly to the Precambrian crustal evolution processes in the Central Indian shield

Résumé :
AbstractSingle grain 207Pb/206Pb zircon ages were determined for granitoids and gneisses which constitute the Archaean basement rocks of the Aravalli craton of Rajasthan, northwestern Indian Shield. The protolith ages for two gneisses, collected from east of Udaipur, are ˜3230 Ma and 2887 Ma respectively. The granitoids display an intrusive relationship with the gneisses and yielded ages ranging between 2666 Ma and 2620 Ma. These ages provide the basis for a geochronological model of evolution of the oldest basement of the Aravalli craton.

Résumé :
AbstractThe Pakistan part of the Himalaya has major differences in tectonic evolution compared with the main Himalayan range to the east of the Nanga Parbat syntaxis. There is no equivalent of the Tethyan Himalaya sedimentary sequence south of the Indus–Tsangpo suture zone, no equivalent of the Main Central Thrust, and no Miocene metamorphism and leucogranite emplacement. The Kohistan Arc was thrust southward onto the leading edge of continental India. All rocks exposed to the south of the arc in the footwall of the Main Mantle Thrust preserve metamorphic histories. However, these do not all record Cenozoic metamorphism. Basement rocks record Paleo-Proterozoic metamorphism with no Cenozoic heating; Neo-Proterozoic through Cambrian sediments record Ordovician ages for peak kyanite and sillimanite grade metamorphism, although Ar–Ar data indicate a Cenozoic thermal imprint which did not reset the peak metamorphic assemblages. The only rocks that clearly record Cenozoic metamorphism are Upper Paleozoic through Mesozoic cover sediments. Thermobarometric data suggest burial of these rocks along a clockwise pressure–temperature path to pressure–temperature conditions of c. 10–11 kbar and c. 700°C. Resolving this enigma is challenging but implies downward heating into the Indian plate, coupled with later development of unconformity parallel shear zones that detach Upper Paleozoic–Cenozoic cover rocks from Neoproterozoic to Paleozoic basement rocks and also detach those rocks from the Paleoproterozoic basement.

Résumé :
The Talchir Formation occurs at the base of the Indian Gondwana sequence resting directly on the Precambrian basement and is conformably overlain by the coal bearing Damuda Group. It is a treasure trove of plant fossils and holds clue to the origin and subsequent rise of Glossopteris flora. Mega and palynofossils of the Talchir Formation reported from various basins of peninsular India are reviewed in the light of new researches. A comparative study of homotaxial flora from other Gondwana continents indicates uniformity and similarity in plant types at the generic level. The flora reconfirms an Early Permian age equivalent to Asselian-Sakmarian for the Talchir Formation.

Résumé :
Let us imagine a graceful bronze image of Dancing Śiva before us. It was perhaps created by a Cola artist in eleventh-century Tamilnad to be installed in a temple to receive offerings of worship, and to parade around the town in a ceremonial palanquin on festival days. From there, this image might have followed any of several paths to stand before us now in a North American museum. Perhaps it was buried under a banyan tree in the fourteenth century when invading Islamic armies, feared for their iconoclasm, marched through the Kaveri delta on their way to Madurai. It could have been disinterred in the nineteenth century, during British rule, by a Tamil workman on a road crew, who showed it to the civil engineer, who brought it to the attention of the District Collector, who passed it on to the Director of Archaeology. In the twentieth century, perhaps, when an international market developed for such objects, it might have ended up in an auction room, a cosmic dance sold to the highest bidder. Or a government expert on culture might have selected it, after its long hibernation in the basement storehouse of its temple, as an image worthy to travel abroad as an ambassador of independent India in the international diplomatics of traveling exhibitions.

Résumé :
AbstractThe COL4A1 gene (COL4A1) plays an important role in vascular basement membrane function and pathogenic mutations have been reported in mice and humans. The gene is expressed mainly in the human brain, eyes and kidneys. Pathogenic mutations result in a vast array of manifestations that can present throughout life including the foetal period. We present a case of an 11-year-old girl with right hemiparesis, congenital cataracts, epilepsy and magnetic resonance imaging (MRI) brain findings with a pathogenic COL4A1 mutation. Many of her clinical features are similar to those of a non-genetic cause of cerebral palsy highlighting the difficulties and delays in making this genetic diagnosis.

Résumé :
Abstract Regional seismic reflection profiles and deep exploratory wells have been used to characterize the subsurface structural trends and seismo-stratigraphic architecture of the sedimentary successions in offshore Indus Pakistan. To improve the data quality, we have reprocessed the seismic data by applying signal processing scheme to enhance the reflection continuity for obtaining better results. Synthetic seismograms have been used to identify and tie the seismic reflections to the well data. The seismic data revealed tectonically controlled, distinct episodes of normal faulting representing rifting during Mesozoic and transpression at Late Eocene time. A SW-NE oriented anticlinal type push up structure is observed resulted from the basement reactivation and recent transpression along Indian Plate margin. The structural growth of this particular pushup geometry was computed. Six mappable seismic sequences have been identified on seismic records. In general, geological formations are at shallow depths towards northwest due to basement blocks uplift. A paleoshelf is also identified on seismic records overlain by Cretaceous sediments, which is indicative of Indian-African Plates rifting at Jurassic time. The seismic interpretation reveals that the structural styles and stratigraphy of the region were significantly affected by the northward drift of the Indian Plate, post-rifting, and sedimentation along its western margin during Middle Cenozoic. A considerable structural growth along the push up geometry indicates present day transpression in the margin sediments. The present comprehensive interpretation can help in understanding the complex structures in passive continental margins worldwide that display similar characteristics but are considered to be dominated by rifting and drifting tectonics.

Une prospection geologique systematique de ces terrains a conduit a la reconnaissance de quatre principaux types de mineralisations dans le socle, le devonien inferieur et le cretace : 1 - une mineralisation stratiforme a zn-pb-ba-f de type sedimentaire - exhalatif omnipresente au sommet de la barre calcaire emsienne (devonien inferieur). 2 - de nombreux filons de types b. P. G. C. A gangue de siderite avec, pour certains, presence importante de barytine ou de fluorine ; ces filons correspondent a une phase de mineralisation tardi-hercynienne, probablement en liaison avec une phase tectonique compressive impliquant un contexte decrochant a composante cisaillante senestre, evoluant progressivement vers une distension nord-sud. 3 - des amas metasomatiques a mg-fe dans la barre calcaire emsienne, pouvant representer le sommet du systeme hydrothermal responsable des filons tardi-hercyniens du socle. 4 - la dissemination de galene dans les calcaires du santonien et de petits amas decimetriques de barytine secants sur la dolomie greseuse du cenomanien ; ces indices traduisent la remobilisation de filons tardi-hercyniens principalement d'apres l'identite des compositions isotopiques du plomb.

Résumé :
The Rush Valley 30' x 60' quadrangle extends southwest and west from the greater Salt Lake City–Provo metropolitan area with land use varied between public, military, Indian reservation, and private. This 1:62,500-scale geologic map will aid the proper management of land, water, and other resources. The map area lies within the eastern Basin and Range Province. Mountain ranges are composed of unexposed basement rocks overlain by exposed Neoproterozoic through Triassic rocks that are about 10.4 miles (16.8 km) thick, and by numerous Tertiary sedimentary and volcanic units (~47 to 20 Ma). The intervening valleys include bedrock covered with Miocene-Pliocene? rocks (~11 to 4 Ma) and Neogene-Quaternary surficial deposits. The map area is on the southern flank of the Uinta-Tooele structural zone. This area is in the Charleston-Nebo (Provo) salient of the Sevier fold-thrust belt and some thrust faults are exposed, but the overall Sevier belt geometry is obscured by extensive Cenozoic cover and later faulting. Following Sevier deformation, calk-alkaline volcanism occurred from several Paleogene volcanic centers (42 to 25 Ma). Extensional tectonism created the distinctive basin and range topography from about 20 Ma to the present. Early extensional basin fill includes Miocene sedimentary and volcanic rocks followed by Pliocene-Holocene surficial deposits primarily from lacustrine and alluvial depositional environments. Valley areas were covered by late Pleistocene Lake Bonneville, and deposits are associated with three levels of regional shorelines. Normal faults cut the ranges and are known to bound some valley margins where not concealed. Although deep drill hole data are relatively sparse, gravity data were used to help constrain basin geometries.
