自然电位与高精度磁法测量在黑龙江青山经营所石墨矿勘查中的应用
Application of Self-Potential and High-Precision Magnetic Survey in Graphite Ore Exploration of Qingshan Management Institute,Heilongjiang Province
摘要
Abstract
This paper explores the application of combined self-potential and high-precision magnetic surveys in graphite ore exploration at Qingshan Management Institute,Heilongjiang Province,and establishes a targeted prospecting model.Geophysical response characteristics of graphite-bearing rock series were determined through systematic physical property tests.High-precision magnetic survey was used to delineate regional lithological backgrounds,and self-potential method was applied to identify mineralization anomalies.Results:Graphite-bearing rock series show weak to non-magnetic properties(geometric mean magnetic susceptibility 4.1×10-5SI)and strong negative self-potential anomalies(minimum field value-1093.16mV).The prospecting model successfully delineated Class I prospect Sp1-1(2.76km2)and Class II prospects Sp1-2,Sp2-1.Industrial ore bodies were confirmed by drilling in Sp1-1,and mineralization was discovered by trenching in Class II prospects.The combined method effectively improves prospecting accuracy and provides technical support for graphite exploration in the Jiamusi Block and similar areas.关键词
