遥感地质线性体与化探信息数字复合处理提取金矿控矿构造信息

The Synthetic Processing of the Remotely Sensed Geological Lineaments and Geochemical Data to Extract the Significant Lineaments in the Terms of Gold-ore Exploration

从遥感图像获取的地质线性体与土壤岩石化探异常数据处理来进行定量分析提取具有控矿构造意义的遥感地质线性体,并从遥感地质环形体影像与化探金异常数据的关系,间接地分析环形体在成矿、控矿中的作用,为地面地质工作者提供找矿构造数值分析依据。研究结果与过去做过的大量地面成矿、控矿地质构造分析结果非常吻合。

The images of remote sensing provide us more detailed and precise information than the general geological investigation.But a dear methology of how to best use lineaments informa- tion in the gold-ore exploration programme is lacking. In this paper the quantitative analyses of the significant lineaments is presented by util- izing the synthetic processing method of the lineaments derived from the satellite data and soil-chemical anomalous data.Furthermore,the minerogenetic role of the ring structures is analysed based on the relationship of the remotely sensed ring structures and geochemical da- ta.This study show a spatial association with gold-ore.The results of study coincide with the field investigation.
