Abstract: In order to ascertain the exploration prospects and provide reference for gold deposit survey with same type, the researchers in this paper summarized the geological characteristics of the Yazhaqu gold deposit, and investigated the controlling factors of NW-trending secondary faults and ductile shear zones on the gold deposit. And the ore-controlling factors, genesis and exploration prosrects of the Yazhaqu gold deposit are also discussed. The results show that the Yazhaqu gold deposit is located between the Kunlun Pass-Maduo-Gander fault and the Keke-xili-Jinshajiang fault, with well-developed NW-trending secondary faults and ductile shear zones. A large number of gold-bearing quartz veins are exposed in fractured alteration zones and ductile shear zones. The content of Au, Ag, Pb, and W of sandstone and slate is high in Qingshuihe Formation of Bayankalashan Group, which provides a material source for the deposit. The NW-trending secondary fault, ductile shear zone and gold-bearing quartz veins are favorable locations for enrichment and integration. The mineralization alteration related to gold mine is well developed, indicating that the deposit is typical tectonic altered rock type and quartz vein type. The NW-trending secondary fault and ductile shear zone in the area are the next prospecting direction.
