摘要:
为研究高分辨率(简称“高分”)遥感卫星数据在东昆仑成矿带找矿预测中的应用,通过遥感地质解译与蚀变异常信息提取,从宏观和多角度开展大型矿集区快速预选和找矿有利地段圈定。以东昆仑成矿带红水河地区为研究区,以WorldView-2卫星图像为主要数据源,通过运用图像纠正、假彩色合成、图像增强、数据融合、遥感蚀变异常信息提取、野外验证、化学分析和地质信息综合研究等方法,对研究区进行了遥感地质解译和找矿预测。结果表明,以高分遥感卫星数据为主的数据源,能够快速圈定找矿有利地段,满足我国西部干旱—半干旱地区的矿产资源勘查和资源评价需求,并为当地矿产勘查工作部署提供基础资料和参考依据。
Abstract:
Through geological interpretation and alteration anomaly information extraction with remote sensing, rapid pre-selection of large ore concentration areas and delineation of potential mineralization areas can be carried out. In this paper, with the Hongshui River region of the East Kunlun metallogenic belt as a case study, by using WorldView-2 remote sensing images as major data source and adopting methods of image rectification, false color composition, image enhancement, data fusion, alteration anomaly information extraction, field validation, chemical analysis and geological integrated analysis, the authors predicted the potential regions of mineral resources. The results show that the remote sensing technology using high resolution satellite images can be used as an effective method for detection of potential mineral resources enrichment region, which can meet the requirements of mineral resources exploration and assessment in the arid and semi-arid regions in West China and provide the basic data and reference for the deployment of mineral resources exploration.
