物化探成果在黑龙江滨东新立屯地区水系沉积物异常查找中的应用

摘要

The 1∶5 million stream sediment anomaly in Xinlitun area of eastern Harbin,Heilongjiang Prov-ince was verified by using the method of 1∶2 million soil measuring,high-accuracy ground magnetic survey and IP gradient array measurement.It was found that there were 1 82 soil anomalies of 1 1 kinds of single element such as Mo,29 combinative anomalies,1 high magnetic anomaly,and 2 IP anomalies.On the basis of comprehensive a-nalysis of its geological background,the trenching work was revealed at the set of geophysical and geochemical a-nomalies and multiple molybdenum ore bodies were found.%利用1∶2万土壤测量、地面高精度磁法测量及激电中梯测量等方法对黑龙江滨东新立屯地区1∶5万水系沉积物异常进行查证，发现Mo等11种单元素土壤异常182处、组合异常29处、高磁异常1处、激电异常2处。在综合分析其地质背景基础上，对物化探异常套合处进行了槽探工程揭露，发现多处钼矿（化）体。
