摘　　要：为查明曙光石场地区各成矿元素和矿(化)体的分布特征,在1∶2万土壤地球化学测量的基础上,对研究区多种成矿元素进行聚类分析和因子分析。研究表明:区内Ag、Pb、Zn、Bi、Sn单元素异常个数多、变异系数值较高,具有较强的成矿潜力;区内Ag-Pb-Zn元素组合异常套和极好,异常强度较强,与岩浆热液型成矿作用相关,具有较好的找矿前景;根据单元素异常的套合情况及元素共生组合规律圈定组合异常六处并进行了槽探工程验证,在Ht-4组合异常处发现一铅锌银矿点,矿体、矿化体产于上石炭统唐家屯组流纹质凝灰岩中。In order to find out the distribution characteristics of ore-forming elements and and ore(mineralization)bodies in Shuguang quarry area,Tonghe County,Heilongjiang Province.Based on an 1∶20,000 soil geochemical survey,this work made clustering,factor and element anomaly analysis of multiple ore-forming elements of the study area.Results show that the study area hosts many single-element anomalies of Ag,Pb,Zn,Bi,and Sn with high coefficients of variation,indicating a great metallogenic potential.The Ag-Pb-Zn element assemblages in the area have excellent combination and large anomaly intensity,which are related to magmatic hydrothermal mineralization,showing a good prospecting prospect.According to the combination of single element anomalies and the law of element symbiosis combination,six combined anomalies were delineated and verified by trench exploration.A Pb-Zn-Ag ore spot was found at the Ht-4 combination anomaly,where the orebody and mineralization body occur in the rhyolite tuff of the Upper Carboniferous Tangjiatun Formation.
