摘要
探讨滇东北地区的铜矿勘查中基于地质模型的遥感找矿方法。不同于常用的先进行图像处理解译,然后在图像上分析已有矿点而后通过相似类比圈定预测区的方法,先通过在研究区内选取典型地区进行野外勘查,构建出区域构造演化模型和成矿演化模型,依据这些模型分析铜矿床的空间分布规律,进而依据这些规律确定遥感找矿模式,有针对性的选取需要通过遥感解译的岩性、构造、蚀变等找矿要素,结合其他对矿床分布起着重要控制作用的多元信息综合分析,在工作区圈定出综合异常区。
The remote sensing exploration measure based on the geological model is applied to copper deposit prospecting in northeast Yunnan.It is different from normal process,which the prediction region is designated in ETM remote sensing image after the image is described,that the geological model is built based on the field work in typical area,and the distribution of ore deposits is derived from the model analysis,and then the remote sensing prospecting model is further developed.Thus,lithology,structure,alterati...
