摘　　要：利用综合物化探方法开展多金属矿产资源预查,在安徽省怀宁县发现了旨田冲银矿点。旨田冲银矿点是怀宁成矿区首次发现的银矿点,该银矿点的矿化体产于志留系高家边组中段,具有层控特征,属新矿种、新层位。旨田冲银矿点的发现为该区地质找矿指明了新的方向,在此着重介绍了该银矿点的矿化情况、综合物化探异常特征和找矿效果,并对该区矿产预查阶段勘查模式进行了总结。The preliminary integrated geophysical and geochemical investigation of polymetallic resources led to the discovery of the Zhitianchong silver ore spot in Huaining County,Anhui Province,which is a silver ore spot discovered for the first time in the Huaining metallogenic area.The mineralized body of this silver ore spot occurs in the middle part of Silurian Gaojiabian Formation and shows stratabound features,belonging to a new species and new horizon.The discovery of the Zhitianchong silver ore spot sheds light on the ore-prospecting work in this area.This paper has described mineralization conditions of this silver ore spot and characteristics of composite geophysical and geochemical anomaly and ore-prospecting effect,and summarized the exploration model formulated at the stage of preliminary ore resource survey.
