Abstract The Zhaishang gold deposit is a superlarge gold deposit in West Qinling Mountains, which is mainly hosted in Devonian and Permian strata and occurs in NWW-trending as well as second-order faults. It contains rich metallic sulfides. In the western part of the ore district, there exists rather thick Tertiary and Quaternary overburden. An integrated analysis of the geological data available shows that metallogenic conditions are fairly favorable beneath the overburden area. Through geophysical and geochemical prospecting work, the authors inferred that there might exist a gold ore body under the overburden area, and shallow drilling has eventually intersected the ore body.
