ON THE PALAEOGEOGRAPHICAL ENVIRONMENTAL EVOLUTION OF PLIOCENE-PLEISTOCENE EPOCH OF THE TANOLHA MOUNTAINS
唐古拉山上新世至第四纪古地理环境的演变(以山口地区为例)

During the Pliocene Epoch, the Tanglha Mountains were low, and broad and level dwarf ranges, not more than several hundred metres above sea level. The greater part of these ranges were a landsurface of peneplanation with an environment of subtropical foreststeppe. There were advanced karst landforms like stone forests etc. Frontmontane and intermontane basins, rivers, and lakes crisscrossed one another, thus forming deposits of fluvit al-lacustrine facies about a thousand metre deep. Since the end of the Pliocene Epoch, the Tanglha mountain has chiefly been characterized by their extensive and great-amplitude archirig and block-faulted uplift.
