Abstract The Early Cretaceous basin of the Liupan Mountain in Ningxia has abundant mineral resources of ointment and salt. Ningxia Geology Bureau has found rock salt layer whose thickness is between 42.38 and 256.11 m in ZK101 and ZK201 in Zhongkangxiang and Guodianzi villages of Yuanzhou District, Guyuan. The area has prospecting potential in finding rock salt minerals. Strata and structures (including fracture), rock salt and other physical parameters or abnormal characteristics were extracted by utilizing existing seismic section, gravity and electrical profile data, combined geological profiles, drilling and logging data. The characteristics of the geophysical prospecting methods were summarized, and the most effective combinations of exploration techniques and methods were proposed. There are nine prospecting targets in the area, and the current survey area is III target area, with the discovery of a rock salt mine of 2.6 billion tons; further work is carried out in II target area, with the discovery of a total amount of 4.9 billion tons of resources in II and III target area. The research results provide important geophysical foundations for regional economic development and prospecting.
