摘要:
为进一步查清辽东水泉地区物化探异常与金多金属矿的因果关系及成矿规律，通过地质填图、土壤地球化学测量、激电测量、工程验证等手段进行综合勘查。结果显示，在水泉地区圈定综合异常3处，成矿元素为一套中低温元素组合；地球物理电性特征为低阻高极化。经验证，Ⅰ号综合异常为矿致异常，地表揭露矿化体，赋存于大理岩中，受北西向断裂控制。钻孔在深部探获铅银矿化体，矿化以黄铁矿化为主，黄铜矿化、闪锌矿化次之；围岩蚀变以硅化为主，碳酸盐化等次之。综合分析认为，D-1低电阻异常、Ⅱ号和Ⅲ号综合异常为进一步找矿的重点方向。

Abstract:
In order to get to know the relationship between regional geophysical and geochemical anomalies and mineralization and metallogenic regularity,the study carried out comprehensive survey such as geological mapping,soil geochemical survey,IP survey and engineering verification.The results show that 3 geochemical survey anomalies are delineated in Shuiquan District,and the ore-forming elements are a set of low-temperature element combination;the geophysical electric property is characterized by low resistance and high polarization.Geochemical anomaly Ⅰ is ore-induced anomaly with revealed mineralized body on the surface and hosted in marbles,controlled by NW fault.Deep in the drill hole has discovered lead-silver mineralized body.The mineralization is mainly pyrite followed by chalcopyrite and sphalerite;the wall rock alteration is mainly silicification followed by carbonatization.Comprehensive analysis thinks that D-1 low resistance anomaly,anomaly Ⅱ and Ⅲ comprehensive anomalies are important future targets.
