以西昆仑塔什库尔干地区为研究区,以WorldView-2高空间分辨率数据为主要信息源,在标准影像图制作基础上,针对性地进行图像增强处理,突出相关控矿要素和矿化信息,开展地质矿产遥感解译;利用ASTER和WorldView-2数据开展矿化蚀变有关的遥感异常信息提取,配合适量的野外调查验证,最终圈定了11处遥感找矿靶区。其中,A级遥感找矿靶区5处,B级遥感找矿靶区3处,C级遥感找矿靶区3处,其为后续区域地质矿产调查项目规划部署和矿产资源勘查评价提供依据;高分遥感技术在西昆仑地区矿产地质综合调查中作用显著,可实现找矿工作的快速突破,值得在相同或类似区域进一步推广应用。
Taking the West Coast Kunming-Takashurgan region as the research area and the WorldView-2 high spatial resolution data as the main information source, based on the standard image map production, the image enhancement processing is targeted, the related ore-controlling elements and mineralization information are highlighted, and the geology Mineral remote sensing interpretation; the use of ASTER and WorldView-2 data mining remote sensing anomaly information extraction, with the appropriate amount of field investigation and verification, the final delineation of 11 remote sensing prospecting target area. Among them, 5 are A-level remote sensing prospecting targets, 3 are B-level remote sensing prospecting targets and 3 are C-level remote sensing prospecting targets. These provide the basis for planning and deployment of geo-mineral investigation projects in the subsequent regions and exploration and evaluation of mineral resources; High-resolution remote sensing technology plays a significant role in the comprehensive survey of mineral geology in the West Kunlun area, which can achieve a quick breakthrough in prospecting work and deserve further promotion and application in the same or similar areas.
