Geological Feature and Prospecting Direction of Pikugou Lead-Zinc Ore in Zhen’an County, Shaanxi

Pikugou lead-zinc ore is located in Shan(Shanyang)-Zha(Zhashui)-Zhen(Zhnán)-Xun(Xunyang)polymetallic metallogenic area in the southern Qinling Mountains, in Gongguan-Huilong town a mercury, antimony, gold, silver, lead, zinc polymetallic metallogenic belt, found in Medial Devonian Yanglinggou Formatian carbonaceous limestone and Upper Devonian Luojiahe Formation carbonaceous phyllite contact zone by limestone side, two lithology between contact in fault, fault occurrence tendency 350° inclination 73°-77°. Based on the regional geology, ore body geology, and the ore controlling factors and so on, the lead-zinc metallogenic elements have obvious zonation, combined with the current drilling to expose and barium element distribution range, determining the lead-zinc ore is currently in the top phase, deep lead-zinc ore has more prospecting potential, combined with the transient electromagnetic anomaly and drilling data found in the line 1-0 and 6-8 there are two lead-zinc concealed orebodies.
