激电中梯法在黑龙江伊春寻找金多金属矿的应用

Application of Induced-current Middle-gradient Method in Finding Gold Polymetallic Deposit in Yichun,Heilongjiang Province

以激电中梯法为基础,探究了其在黑龙江伊春地区地质矿产调查的应用,对实际测量数据进行处理,编制图件,综合地质、化探、遥感等资料进行推断解释。通过对视电阻率ρs和视幅频率Fs的解释以及推断,结果表明:本次面积性工作圈定4处激电视幅频率异常和4处高阻异常,推断7处断裂构造带;剖平性工作发现1处高阻异常,2处视电阻率异常,推断1条断裂构造带。并对其中有成矿可能性较好的异常进行了推断解释,对异常的走向、范围进行了分析,为下一步对本区金属矿床的找寻提供了重要依据。

This paper is based on induced-current middle-gradient method, and explores the application of geology and mineral resources survey in Yichun, Heilongjiang province, processing of the actual measurement data and explaining data on compilation maps, comprehensive geological, geochemical exploration, remote sensing. Interpretation and inference of apparent resistivity(ρs) and apparent frequency(Fs). The results show that the work area delineated 4 laser apparent frequency anomalies and 4 Apparent resistivity anomalies, inferred 7 fault belt. The profile discovered 1 high resistivity anomalies, the apparent resistivity of the 2 anomalies, inferred the 1 fault zone. The paper also gives an explanation and interpretation of good possibility of metallogenic anomaly, and analyzes the direction and scope of the anomaly, which provides an important basis for the next step to search for the metal deposits in this area.
