摘要:
在黑河市伊洛特河地区开展1∶5万水系沉积物测量的基础上，对样品分析结果进行统计，结合地质背景，对11种元素含量分布特征、相关性及组合异常特征的总结发现：Au、Ag、Mo等元素发生了不同程度的富集，具有形成该类矿床的可能。圈定了水系沉积物组合异常42处，通过分析元素相关性、成矿地质背景，认为组合异常HS-10、HS-36、HS-37具有较好找矿潜力。针对组合异常HS-37开展了1∶2万土壤测量和地表工程验证，在Au元素异常浓集中心发现了金矿体，最高品位1.26×10-6，最大宽度3.0 m。表明1∶5万水系沉积物测量在与伊洛特河地区相似的植被覆盖严重地区的找矿勘查中具有良好的应用价值。

Abstract:
On the basis of 1∶50 000 stream sediment survey in Yiluote River area of Heihe City,the analysis results of the samples are statistically analyzed.Based on the geological background,the distribution characteristics of element content,element correlation,and combined anomaly characteristics of 11 elements are summarized.It is found that Au,Ag,Mo and other elements have been enriched to varying degrees,which is likely to form such deposits.Based on the analysis of element correlation and the geological background of mineralization,it is concluded that the combined anomalies HS-10,HS-36 and HS-37 have good potential for ore exploration.1∶20 000 soil survey and surface engineering verification were carried out on the combined anomaly HS-37.Gold ore bodies were found in the center of Au element abnormal concentration,with a maximum grade of 1.26×10-6 and a maximum width of 3.0 m.It shows that the 1∶50 000 stream sediment survey has good application value in the prospecting and exploration of areas with severe vegetation cover similar to the Yiluote River area.
