摘　　要：利用水系沉积物地球化学参数特征、元素组合特征,对黑龙江省卫林地区的12种元素进行了数理分析。通过元素地球化学特征分析,发现Au、As、Sb、Cu、Mo、Bi相对离散程度大,为主成矿元素;通过对水系沉积物测量数据R型因子分析,12种元素可分为6类。根据成矿地质条件、地球化学异常特征,将研究区划分为官五爷大山铜成矿远景区、大头山钼成矿远景区、404.2高地钼成矿远景区。Based on the geochemical parameter feature and element assemblage feature of stream sedimentary samples,the mathematical analysis of 12 elements is carried out in Weilin area of Heilongjiang Province.According to the geological characteristics,it is shown that the major ore-forming elements are Au,As,Sb,Cu,Mo and Bi with a great relative dispersion extent.12 elements can be divided into six categories through R-type factor analysis of stream sedimentary survey data.According to the metallogenic geological condition and geochemical anomaly characteristics,the study area is divided into Guanwuyedashan Cu metallogenic prospective area,Datoushan Mo metallogenic prospective area and 404.2 highland Mo metallogenic prospective area.
