摘要: 介绍了采用综合物探方法在江苏南京南门头勘查区进行铁铜多金属矿找矿靶区预测的应用与研究。通过对该区重、磁、电异常分布特征进行分析,对圈定的重低磁高、重高磁高和电性异常进行了解释和推断,结合地质和物性资料,选择区内重要异常进行剖析,并通过钻孔得到了验证,圈定了3处铁铜多金属矿找矿靶区,取得了较好的找矿效果。Abstract: The author mainly introduces the application and research of comprehensive geophysical prospecting method in iron and cop?per poly?metallic ore prospecting target area in nanmentou exploration area of Nanjing,Jiangsu province.By analyzing the gravity?mag?netic?electrical abnormal distribution characteristics,to explain and infer the anomalies delineation of gravity low and magnetic values high gravity high and magnetic values high and electrical property. The selection of important anomalies in the area are analyzed com?bined with geological and geophysical data,and has been verified by drilling holes,and three iron and copper poly?metallic ore prospec?ting target areas delineated and better prospecting results achieved.
