新疆戈边山地区遥感地质特征分析

研究区地处新疆若羌县东北戈边山一带,气候、交通条件恶劣,地质工作程度较低。文章利用多光谱ETM、ASTER卫星数据以及高分辨率Quickbird卫星数据图像,结合已有的地质矿产资料,对区内的岩性地层、地质构造开展了不同比例尺的遥感地质解译工作,同时利用ASTER数据提取了区内羟基及铁染异常信息,结合野外调查成果,分析了戈边山地区成矿地质背景,总结了遥感找矿信息,为研究区进一步开展地质找矿工作提供了基础遥感技术资料。

Analysis on remote sensing geological characteristics of Gebian Moutain area in Xinjiang

The study area is located in the Gebian Moutain area in the northeast of Ruoqiang, Xinjiang, with poor weather condition and less geological works there. In this paper, we used multi-spectral ETM, ASTER satellite data and high resolution Quickbird satellite image in combining with the existing geological and mineral data and carried out different scale remote sensing geological interpretation works on the lithologic stratigraphy and geological structure in the area.We also extracted the information of hydroxyl and iron staining through ASTER data. Based on the field investigation results, we analyzed the metallogenic geological background and summarized the information of remote sensing for the Gebian moutainarea, provided the basic remote sensing technology data for further geological prospecting.
