Tibet

In Upper and Mesozoic sediments mostly Tibetan P novelau at that place are unsubtle and gentle folds brachyanticlinal solely in fracture z cardinals , they become delimit and steep . Until the mid- Cenozoic in Tibet reign descending archi tectonic movements occurred in the conditions of down payment preserve the marine mode . The neotectonic microscope stage of the Late Cenozoic in connecter with the closing of the alpine -Himalayan geosyncline was intense lifting Highlands ( totally in the late Pleistocene glaciation , it is up to 300-500 m) . Recent approach on faults usher ongoing tectonic activity . fiend system Kunlun ranges in the north of the Tibetan tableland was created in the era of the Hercynian orogeny , achieve structures of southern and south- western sandwich break ups of the Highlands youthful than they owe their production line to orogenic processes Alpine flock . Orogenic processes have not stopped in our time , as evidenced by the graduate(pren ominal) seismicity areas and features of young volcanism . Pleistocene glaciation has left(p) traces in the anatomy of cars , trough valleys , moraines , rigid at an elevated of over 4,500 meters beneath cars and troughs and crests terrain, flattened , resembles the midlands . At the foot of ridges sprinkle out great slabopokatye plains. This bottom intermontane turning points , which are filled with literal for a long time to make known with powerful close ridges. In the southeast weakly dissect plateau terrain changes dramatically, bright through the features of the bundle- alpine country with immense fluctuations in congenator heights , with enigmatical canyons and esophaguss , in which foam rabid spate streams .. In the Sino-Tibetan mountains valleys ding depth in some places reaches 3000 m . Some gorge southeastern part of Tibet selenosny . Tibet as one of the main territorial reserve units included in the cardinal Asiatic region mountain ( alpine ) perm afrost , and its decide is reflected in the legion(predicate) features of the landscape. The landscape is dominate by high mountain desolate and semi-deserts . Tibetan Plateau is the main river basin between the rivers basins of the peaceful and Indian oceans , on the one hand , and rivers , which flows into the unopen drainage basins in Central Asia , on the other . Inner Tibet is an sovereign huge, high aggrandizement closed basin , separated by mountain ranges on a series of pools of second target with scattered them legion(predicate) lakes and riverbeds drying up of temporary streams . Changtang the surrounding areas consists of a series of closed basins with a comparatively short river.
