摘要
通过提取遥感找矿地质异常信息,从宏观和多角度预测矿床存在的有利区域。以东昆仑—阿尔金地区为例,通过运用影像纠正、假彩色合成与彩色空间变换、图像增强处理(比值、主成分分析等)、掩膜处理、数据融合以及遥感异常信息多层次筛选技术、影像镶嵌、地质信息综合分析等方法,提取与成(控)矿作用相关的蚀变异常信息和构造信息,确定了基于蚀变异常与线环构造信息的典型矿物遥感找矿模型,并结合多源信息对东昆仑—阿尔金地区进行了成矿预测。
Remote sensing technology can get spectral information and tectonic information effectively and predict the ore-forming areas by extracting the remote sensing anomaly information from macroscopic view and multi-angles.In this paper,the authors have taken the metallogenic belt of East Kunlun and Altun mountains as an example,extracted the alterative anomalies information and tectonic information about the mineralization and ore-controlling structures by the use of image correction,pseudocolor composite and color spatial conversion,image enhancement,mask processing,image fusion,image mosaic,geological information comprehensive analysis and so on,established the prospecting model of remote sensing according to the alterative anomalies information,linear structure and ring structure,and carried out the metallogenic prediction in east Kunlun and Altun Mts.with the multi-source information technology.
