以1∶20万区域水系沉积物数据为基础，对黑龙江东安-汤旺河地区13种元素进行了相关性分析、聚类分析和主因子分析。分析结果表明，元素异常组合呈有规律的分布，高温元素异常组合分布在研究区西侧，而低温元素异常组合出现在研究区东侧。在以分形为主要手段确定异常下限后，认为在研究区东部，与中低温元素伴生的 Au 矿床找矿潜力较大。结合地质、物探以及已知矿点的信息，圈定多元素异常34处，划分出4个找矿远景区。

Based on the 1 ∶200,000 geochemical data of stream sediments in Dongan -Tangwanghe region, Heilongjiang Province,correlation analysis,cluster analysis and principal factor analysis conducted on 13 ele-ments show systematic and regular element distributions.Anomalies of high-temperature elements and low-tem-perature elements occur in the western and eastern parts of the study area,respectively.Though computing the threshold by fractal analysis,it is proposed that the eastern area has substantial potential for exploring Au deposits associated with middle-to low-temperature elements.Combining the information of geology,geophysics and known deposits,this paper delineates 34 element anomaly associations and 4 potential prospecting areas.
