摘要
基于中、高分辨率遥感数据,对西藏别若则错地区开展了蚀变信息提取与找矿预测。首先利用ASTER中等分辨率遥感数据,快速获取成矿地质背景信息及遥感蚀变信息,优选找矿有利区。其次利用World View-2高分辨率遥感数据开展找矿有利区的岩性构造解译,重点解译中酸性侵入岩体、火山机构、断裂、地层岩性等控矿要素。最后在野外查证成果基础上,圈定了3处找矿靶区,取得了良好的应用效果。
Based on the interpretation of intermediate and high resolution remote sensing data, the alteration information extrac- tion and prospecting prediction in the Bicruozecuo area, Tibet were carried out. Firstly, the information of geological background and alteration were extracted using ASTER moderate resolution remote sensing data, then, the favorable prospecting areas were delineated ; Secondly, the lithologiea] and structural interpretation were carried out in the favorable prospecting areas using the WorldView-2 high resolution remote sensing data, especially the interpretation of intermediate-acid intrusive rocks, volcanic diatreme, fractures litbology and strata etc. ; Finally, three prospecting target areas were selected for the field investigation and verification, and good exploration effect was achieved.
