Abstract: A bstract: The right-slip Talas-Ferganhna fault plays significant roles in controlling the strata, structures and petroleum geologic features in Kashi sag since Late Triassic. During the Late Triassic-Middle Jurassc,Kuzgongsu and Kezletao fault basins probably disconnected with each other occurred in the sag, with developed rifted-style source rocks of Lower-Middle Jurassic. During the Neogene-Quatemary, the relevant strike-slip deformation of the fault occurred and controlled the petroleum traps and accumulations in Kashi sag.

Key words: Tarim basin, Kashi sag, Talas-Ferghana fault, control, source rock, oil-gas trap, hydrocarbon accumulation
