Abstract:

Both Central Asia and Northwestern China were located in the south margin of Eurasian Continent in Mesozoic. Since Jurassic, they both have experienced similar tectonic evolution, i. e. the extension tectonics in JurassicPaleogene and compressive tectonics in Neogene-Quaternary. The collision of Indian Plate with Paleo-Eurasian Plate resulted in present style of mountain-intercalated basins. The basins possess rich oil and gas resources, favourable poolforming conditions and different post-reformtion. Foreland thrust belts are common structural features in piedmonts of the basins, but their internal structures are varied greatly. Neotectonisms influence strongly on oil-gas accumulation.

Key words: Central Asia, Northwestern China, basin, tectonic evolution, oil-gas potential
