Detrital zircon data have recently become available from many different portions of the Tibetan–Himalayan orogen. This study uses 13,441 new or existing U‐Pb ages crystals strata in Lesser Himalayan, Greater and Tethyan sequences Himalaya, Lhasa, Qiangtang, Nan Shan–Qilian Shan–Altun Shan terranes Tibet, platformal Tarim craton to constrain changes provenance through time. These constraints provide information about paleogeographic tectonic evolution Tibet–Himalaya region during...

The Himalayan-Tibetan orogen culminated during the Cenozoic India -- Asia collision, but its geological framework and initial growth were fundamentally result of multiple, previous ocean closure intercontinental suturing events. As such, provides an ideal laboratory to investigate signatures process in general, how Earth9s highest largest orogenic feature formed specific.

The Qiangtang metamorphic belt (QMB) in central Tibet is one of the largest and most recently documented high-pressure (HP) to near-ultrahigh-pressure (near-UHP) belts on Earth. Lu-Hf ages eclogite- blueschist-facies rocks within QMB are 244–223 Ma, indistinguishable from age UHP metamorphism Qinling-Dabie orogen.

In the Shiquanhe area of far‐western Tibet, mid‐Cretaceous strata lie unconformable on ophiolitic melange and Jurassic flysch associated with Bangong‐Nujiang suture zone. On basis our mapping geochronologic studies, we suggest that these Cretaceous were shortened by >57% over a north south distance 50 km during Late Cretaceous‐early Tertiary time. The Narangjiapo thrust placed Permian >20 strata. North thrust, >40 shortening was accommodated directed Jaggang system involves strata,...

Abstract Siliciclastic sedimentary rocks derived from the southern Lhasa terrane, sitting depositionally upon of northern Indian passive continental margin, provide an estimate age initial contact between parts and Asian plates. We report sedimentological, petrological, geochronological data Upper Cretaceous‐Paleocene strata in Sangdanlin section, located along flank Indus‐Yarlung suture zone Tibet. This is probably most proximal, therefore oldest, record India‐Asia collision. These were...

A long‐standing problem in the geological evolution of India‐Asia collision zone is how and where convergence between India Asia was accommodated since collision. Proposed ages vary from 65 to 35 Ma, although most data sets are consistent with being underway by 50 Ma. Plate reconstructions show that Ma ∼2400–3200 km (west east) occurred, much more than 450–900 documented Himalayan shortening. Current models therefore suggest post‐50 north Indus‐Yarlung suture zone. We review kinematic...
