摘　　要：皇城山银矿是典型的火山岩型中低温热液矿床。矿体、控矿构造、岩浆岩、赋矿地层以及周围地质体之间存在某种物性差异,因而有明显的地球物理异常特征,构成了银矿床重要的地球物理找矿标志。作者试图在矿床地球物理特征研究的基础上,总结地球物理找矿模型,以期配合、指导正在进行中的大别山北坡多金属成矿带的普查找矿工作。Huangchengshan Ag deposit is a typical volcanic-hosted low to moderate temperature hydrothermal deposit.The physical property differences among orebody,ore-controlling structure,magmatic rock,orebearing formation and peripheral geologic body result in significant geophysical anomaly characteristics and thus form the important clues for geophysical prospecting of Ag deposits.Based on the study of geophysical characteristics of the deposit,the author attempted to present the geophysical prospecting model to assist and guide the on-going general prospecting work in the polymetallic metallogenic belt on the north slope of Dabieshan.
