West Qinling orogenic belt is located in the abdomen of China, developing the Indosinian granite, and the Au deposit enriched. Tianzishan area located in Liziyuan village, Beidao district of Tianshui, Gansu province, is situated in West Qinling orogenic belt. Tianzishan rocks is located in the splicing turning parts between North Qinling Caledonian orogenic belt and Middle Qinling Hercynian fault fold belt, under the control of Shujiaba deep fracture, which is intruded into the lower Neoproterozoic Muqitan Formation and Paleozoic Taiyangsi Formation. The wall rock shows different degrees of alteration, such as angle alteration, silicification and sericitization. Tianzishan rocks are mainly consists of monzogranite, whose mineralization is controlled by NW trending ductile shear zone.
