Abstract

The Junggar Basin is an important oil-and gas-bearing basin, with thick source rocks, of Carboniferous, Permian, Triassic and Jurassic ages. Hydrocarbon accumulations are controlled by major faults which trend NNW, NW and NE; NE-striking reverse faults constitute the Kelemay thrust-zone in the NW basin margin; those trending NW are of lesser importance; and those trending NNW on the southern basin margin control the formation of en échelon anticlines (Kuang, 1989), which are important sites of hydrocarbon accumulations.
