The distribution patterns of environments and facies in different stages of Cretaceous (Lower Cretaceous) in Kuqa depression are discussed from point of view of depositional palaeogeography in this paper.

Magnetic minerals produced in each stage of the sedimentation evolusion process of the rocks carry information about the palaeoenvironments in their occurrence, and thus they become direct objects of study in sedimentary palaeogeography and environment magnetism.
