摘要
Depositional succession of the Lower Cretaceous Xiagou-Zhonggou Formations is widely distributed in Hanxia of the northern Qilian Mountains. Correlation and synthesized analysis of stratigraphy,depositional facies and lithological associations in Hanxia and its adjacent areas(Changma basin and the western Jiuquan basin) illustrate that the Xiagou and Zhonggou Formations in Changma to the southwest of Hanxia,are interpreted as deposits of shallow lacustrine and meandering river facies,and then Hongliuxia to the north of Hanxia was shallow lacustrine environment,Xinminpu(to the northeast of Hanxia),however,is mainly and meandering river facies.A dispositional model of the Lower Cretaceous Xiagou and Zhonggou Formations is synthesized finally.
