Sedimentary facies of the Triassic-Jurassic strata in the Tarim Basin, Xinjiang

The Triassic-Jurassic strata in the Tarim Basin, Xinjiang are arranged into four distinctive continental basins, in which the inland lakes and continental deposits predominate apart from the shorter-period marine flooding during the Early Triassic and Late Jurassic. In addition, the fan deltas are also well developed due to tectonism. The Kuqa Basin has the same lake area as that of the North-Central Tarim Basins, but the location of the lake area drifted off its original position. The Southwest and Southeast Tarim Basins are highly variable. The Triassic lake basins are relatively small and disconnected. The Jurassic lake basins become larger and connected in the southwestern and southeastern parts of the Tarim Basin.
