摘要
山门银矿床位于大黑山断隆南部,为浅成低温热液银矿床.通过对矿床地质特征、地球物理特征、矿石类型、成矿期次、流体包裹体及稳定同位素地球化学特征的研究,确定该矿床的找矿标志为北北东向张性断裂,硅化,Ag、Au、Pb、Zn为主的土壤化学异常,低电阻率异常.成矿温度为低温,低盐度,成矿流体为以大气降水为主.该标志对于在大黑山条垒一带寻找同类矿床具有一定的指导意义.根据以上标志,划分出3个成矿远景区.
The Shanmen silver deposit,located in the south part of Daheishan faulted uplift,is of epithermal type.Based on the study on geology,geophysics,types of ores,stages of mineralization,fluid inclusions and stable isotope of the deposit,the significant prospecting indicators for the deposit are determined,i.e.NNE-trending tensional faults,silicification,low resistivity electric field,soil chemical anomalies of Ag,Au,Pb and Zn.The metallogenesis is in low temperature,with low salinity.Meteoric water dominates the ore-forming fluid.
