摘要
本文从金顶铅锌矿床所处的大地构造背景、控矿因素、成矿规律、硫铅同位素组成及矿质来源等方面论证了该矿床是同生沉积成矿作用、沉积—改造成矿作用及后期幔源矿质叠加成矿作用的综合产物,是一个多来源、多成因的超大型复合成因铅锌矿床。
Jinding Pb-Zn deposit is geotectonically located in the contact zone of China Plate and IndiaPlate. In the mine area took place Mesozoic-Cenozoic fault basin, arch, nappe and fault. Such con-centration of tectonics is favourable for mineralization in the area. The depost is doublely controled bytectonics and proper lithologies on both sides of the nappe structure. It is characterized by endogenicand epigenic mineralization. Sulfur of sulfide is mainly derived from reduction of sulfate in marinebasin by bateria. Maybe, some comes from the hypogene. Pb isotope of galena can be divided intocrust lead and mantle lead. Geological and geochemical characteristics show that Jinding deposit is amultiple genesis, super-sized Pb-Zn deposit formed by synsedimentation and later reformation.
