The Jurassic rocks in the northeast margin of Qaidam Basin show different types of sedimentary environments like alluvial fans, braided rivers, and lakes. These environments were shaped by tectonic movements in the region. The sedimentary history of the area can be divided into two stages: a faulted lake basin stage in the Early to Middle Jurassic, and a depression lake basin stage in the Late Jurassic.
