摘要
本文对金顶铅锌矿床的成矿地质背景、矿床地质特征及其它成矿信息进行了分析,初步认为该矿床成因是以幔源去气—热液沉积作用为主,成岩定位后期改造而形成的层控矿床。主要成矿金属物质来自上地幔,硫主要来自海相、陆相有机质和地层中的硫化物,井有少量壳源金属和深源硫参与成矿。
Based on the geological setting, characteristics and some other mineralization information of the deposit, the deposit is considered to be of stratabound type. Depneumatolysis of the mantle source and hydrothermal-sedimentary processes predominate in the mineralization. The ore-location is formed in diagenesis , and reformed in epigenesis. The main ore-forming metals are derived from the upper mantle, a few of them from the crust; sulfur comes mainly from marine sediments, organic materials in continent facies and sulfide in the strata. There is a little deep-seated sulfur in the deposit.
