Western Central Asia Evolution

We propose a model of tectono-stratigraphic evolution of Western Central Asia since the Late Palaeozoic. The evolution during this 300My-long period is mainly controlled by successive accretions of continental blocks and collisions that succeeded in Late Carboniferous-Early Permian, Late Triassic-Early Jurassic, Early Cretaceous and Cenozoic times. These orogenies controlled the deposition of thick clastics sequences in the surrounding platforms and basins. The eastern part of Tien-Shan, emerged since the Late Paleozoic, was the main source of sediments during the Mesozoic. Between the main orogenic periods the sea periodically invaded part of the domain. It is only in Cenozoic, with the beginning of the India/Eurasia collision, that the whole western Central Asia domain was emerged.
