Abstract: A set of very typical turbidite sequence is developed in the middle of Kuqa depression. Among therocks, mark structures showing turbidty features frequently occur and have charaterlstic Bouma se-quence. Turbidity deposits passing through the scarp zone of braid delta front in the northeast Kuqa de-pression enter the centre of the basin. As the Late Triassic is a stable subsiding stage of the depressionand the landform of lakebed is smooth, turbidte sequenceis relatively thinner and only D turbiditefaciesis developed. Obviously it is a very typical distal turbidite. Hydrocarbon source rocks of deep lake faciesand reservoirs of braid deltas and cap rocks associated with turbidite are well developed. It has beenproved that M esozoic strata have good potentials for exploration of oil and gas in this region.
