【摘要】 前坪锌铅矿区位于华北地台南缘,华熊台缘坳陷卢氏—栾川台缘陷褶断束中,区内断裂构造发育,岩浆活动强烈,锌铅矿床类型为岩浆热液充填交代型。矿体呈脉状透镜状产出,矿石呈多孔状、蜂窝状、角砾状。围岩主要蚀变类型包括有绢云母化、碳酸盐化、硅化、黄铁矿化。通过对研究区成矿地质背景、地质特征及控矿因素进行探讨,总结了研究区找矿标志。更多还原

【Abstract】 The qianping zinc-lead deposit is tectonically located in the southern margin of the North China block and the Huaxiong plateau marginal depression Lushi—Luanchuan depression fold fault one bunch, with developed fault structures and intense magmatism.the Pb-Zn deposit belongs to hydrothermal filling and metasomatic type.The orebodies occur as veins and lenses,with ores in vuggy honeycomb and brecciated styles.The alternations involve mainly silicification is sericitization,carbonation,silicification and pyritization. Based on the geological background,geological characteristics and ore-controlling factors of the investigated area,the prospecting criteria are summed up.更多还原
