摘　　要：石灰窑铜多金属矿区地处索伦—西拉木伦缝合带北部,成矿地质条件和找矿前景较好。通过1∶1万土壤地球化学测量,对10种成矿元素进行相关性分析、聚类分析、因子分析、单元素异常分析和综合异常分析,共圈出单元素异常64处,综合异常5处。结果表明,Au、Cu、Mo、Bi异常高值点多、离散性强,地质及地球化学条件优越,成矿潜力大。在此基础上,结合成矿地质条件和矿化特征,优选出找矿靶区2处。对Ⅰ号找矿靶区单元素异常浓集中心进行工程验证,发现2条矿化蚀变带,进一步证实石灰窑铜多金属矿区找矿前景较好。The Shihuiyao Copper Polymetallic District is located in the northern part of the Sauron-Silaran suture zone,and its metallogenetic geological conditions and prospecting potentials are favorable.Based on the 1∶10000 soil geochemical survey,the correlation analysis,cluster analysis,factor analysis,single element anomaly analysis,and comprehensive anomaly analysis of 10 kinds of ore-forming elements were carried out.And 64 single element anomalies and 5 comprehensive anomalies are delineated.The result shows that Au,Cu,Mo and Bi anomalies have multiple abnormally high points and high discreteness,indicating superior geological and geochemical conditions and great metallogenic potentials.Based on that,according to metallogenic geological conditions and mineralization characteristics,2 prospecting targets were selected.The single element anomalous concentration center in prospecting targetⅠis verified in the field,and 2 mineralized alteration zones are discovered,further demonstrating good prospecting prospects in Shihuiyao Copper Polymetallic District.
