The geotectonic structure of this area is located in the North Kunlun Magmatic Arc (Ⅳ-8-3) the East Kunlun Arc Basin (Ⅳ-8), the Qin-Qi-Kun Orogenic System (Ⅳ). The exposed strata in the area are the Lower Proterozoic Jinshuikou (Rock) Group, with structural faults spreading in the NW-NW direction, and the intrusive rocks formed during the Variscan period. The gold (mineralized) body in the area is mainly controlled by structure, and the NNE-trending secondary structure is the main ore-controlling structure in the area.
