Paleocene–Eocene record of ophiolite obduction and initial India-Asia collision, south central Tibet
[1] Uppermost Cretaceous to Eocene marine sedimentary sequences occur both to the south and north of the Yarlung Zangbo suture in south central Tibet. They consist of Indian-margin strata of the northern Tethyan Himalaya and Asian-margin strata of the Gangdese forearc. Both assemblages are characterized by major changes in depositional environment and sedimentary provenance at 65 Ma and an appe...
متن کاملFlexural bending of southern Tibet in a retro foreland setting
The highest elevation of the Tibetan Plateau, lying 5,700 m above sea level, occurs within the part of the Lhasa block immediately north of the India-Tibet suture zone (Yarlung Zangbo suture zone, YZSZ), being 700 m higher than the maximum elevation of more northern parts of the plateau. Various mechanisms have been proposed to explain this differentially higher topography and the rock uplift t...
متن کاملIndus-Yarlung-Tsangpo Suture Zone Concept- A Second Opinion
It is believed that Greater India migrated from the southern hemisphere, collided with Gondwanaland, Angaraland and Cathaysia, thereby closing an intervening oceanic Tethys along the Indus-Yarlung-Tsangpo Suture Zone (IYTSZ).The suture zone is placed along the Chaman Fault in the Baluchistan-Afghanistan area in the west, and the Indus-Yarlung-Tsangpo in the north, whereas along the east from Th...
متن کاملMesozoic and Cenozoic tectonic evolution of the Shiquanhe area of western Tibet
[1] In the Shiquanhe area of far-western Tibet, midCretaceous strata lie unconformable on ophiolitic melange and Jurassic flysch associated with the Bangong-Nujiang suture zone. On the basis of our mapping and geochronologic studies, we suggest that these Cretaceous strata were shortened by >57% over a north south distance of 50 km during Late Cretaceousearly Tertiary time. The Late Cretaceous ...
متن کاملRaising tibet.
Thermochronologic, sedimentologic, oceanographic, and paleoclimatic studies suggest that rapid uplift and unroofing of southern Tibet began about 20 million years ago and that the present elevation of much of the Tibetan plateau was attained by about 8 million years ago. Hypotheses advanced to explain the tectonic evolution of the India-Asia collision, which began about 40 to 50 million years a...
