河南嵩县双元沟铅锌矿地质特征及找矿方向

河南省嵩县双元沟铅锌矿位于华北陆块南缘外方山断隆带上,华北陆块南缘多金属成矿带的东段,黄庄—付店—土门钼铅锌银金成矿带内,矿体赋存于NE向或者与SW向构造带交汇处,呈脉状、透镜状;矿体形态、产状严格受断裂带控制,断裂交汇处为富厚矿体赋存的有利部位,矿床围岩蚀变较弱,铅锌矿以硅化、钾化为主,少量绿泥石化、褐铁矿化。钼铅矿以硅化、萤石矿化、碳酸盐化为主,次为锰矿化、黄铁矿化。为中—低温石英脉型铅锌矿床。

The geology feature and prospecting criceria of the Shuangyuangou Pb-Zn deposit in Songxian of Henan province

The Shuangyuangou Pb-Zn deposit was in Henan Songxian, located in the southern margin of the North China Craton. And the deposit was a part of the Huangzhuang-Fudian-Tumen Mo-Pb-Zn-Au-Ag metallogenic belt. The orebody was controlled by the NE and/or SW fault. And the vein, lenticular Pb-Zn orebody occured in the intersection place of the two fault. The wall-rock alteration was different between the Pb-Zn and Mo-Pb mineralization. The alteration of the Pb-Zn mineralization mainly includes silication, potassic, minorly includes chloritization and limonitization. The silication, fluorition,carbonation are main alteration in the Mo-Pb mineralization. The Mn-deposits and pyritization are minor. The Pb-Zn and Mo-Pb deposits in the Shuangyuangou are quartz vein type mid-low temperature deposits.
