云南思姑锡矿区地质、化探、遥感多元信息综合找矿研究
|
摘要
文章通过对地质、遥感、地球化学等多元地学数据的找矿信息提取和综合处理技术研究,形成了一套多元信息综合找矿的技术。选择Sn、Cu、Pb、Zn、Ag、Mo等6个元素,对矿区原生晕进行了R型聚类分析、因子分析等分析,并以传统化探处理方法(平均值+n×标准差)确定异常下限圈定异常区域;将遥感、化探与地质信息融合并进行综合分析,总结出矿区矿体的产出状态和成矿地质特征。经野外工作、探槽及坑道验证,证实了预测的准确性。
Ore prospecting method of multivariate information gained by synthetic analyses on remote sensing images,geological data and geochemical information is introduced and index for ore prospecting has been set up.Sn,Cu,Pb,Zn,Ag and Mo elements are chosen for primary halos with R-type cluster analysis and factor analysis.Traditional geochemical data processing method with geochemical anomalous line(mean + n × standard deviation)is adopted to define geochemical anomaly.After synthetic analyses of multivariate information,ore occurrences and mineralizing characters are summarized.Veracity of forecasting by tunnel and trenching exploration is approved.
