摘　　要：黑龙江滨东松江地区位于小兴安岭—张广才岭金、钼、铜、铅锌和富铁成矿带,成矿地质条件优越,具有良好的找矿潜力。本文基于水系沉积物1∶5万地球化学调查数据,发现滨东松江地区Bi、Sb、As、Ag、Cu、Zn、Pb等元素平均值高于森林沼泽区水系沉积物平均值,As、Ag、Bi、Cu、Zn表现出显著富集,Au、Mo表现出较强富集。R型聚类分析、相关分析和因子分析结果表明本区Ag、Cu、Zn、Au、Bi和Mo、W两组元素彼此相关性较好。综合研究发现本区Cu、Zn、W、Mo等元素具有一定的找矿潜力,共圈定综合异常43个,根据研究区化探综合异常的空间展布情况及元素组合特征,结合区内已发现矿(化)体分布特征,初步在区内划分出3处成矿远景区,为黑龙江滨东地区找矿潜力分析、成矿潜力研究提供了科学依据。Songjiang area of East Harbin,Heilongjiang province is located in the Au-Mo-Pb-Zn-Fe Metallogenic belt of lesser Xing’an-Zhangguangcai Range,with favorable metallogenic geological conditions and good prospecting potential.Based on the geochemical data of 1∶50000 Stream Sedimens,it is found that the average values of Bi,Sb,As,Ag,Cu,Zn and Pb in Songjiang area of East Harbin were higher than forest-swamp area;As,Ag,Bi,Cu and Zn show significant enrichment,Au and Mo show strong enrichment.The R-mode cluster analysis,correlation and actor analysis indicate that Ag,Cu,Zn,Au,Bi and Mo,W have a good correlation in this area.The author think that Cu,Zn,W,Mo have prospecting potential in this area by comprehensive research.Forty-three comprehensive anomalies were delineated in this work.According to the spatial distribution characteristics of geochemical comprehensive anomalies,element combination features and distribution characteristics of discovered ore(mineralized)bodies,the study area is divided into three metallogenic prospective areas which provide a scientific basis for the analysis and the study of prospecting potential in Songjiang area of East Harbin.
