摘　　要：薄刀岭银金矿是典型的中型韧、脆性剪切带型矿床。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,构成了银金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,总结地球物理找矿标志,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。Bodaoling Ag-Au deposit is a typical middle-sized ductile-brittle shear zone deposit.The physical property differences among orebody,ore-controlling structure,magmatic rock,ore-bearing horizon and pe-ripheral geological body result in obvious geophysical anomaly characteristics which constitute important clues for geophysical prospecting in the Ag-Au deposit.Based on the study of geophysical characteristics of the deposit,the author attempted to summarize the clues for geophysical prospecting so as to provide assis-tance and guidance for on-going general survey and prospecting in the polymetallic metallogenic belt on the north slope of Dabieshan.
