摘　　要：文章运用GF-1遥感数据,在柴达木盆地北缘大柴旦地区开展遥感地质矿产调查技术方法研究。采用图像处理技术,制作了研究区的GF-1遥感影像图。在此基础上,对该区地质构造、岩性地层及铁染蚀变异常等信息进行了提取。通过综合分析,圈定了2处遥感找矿预测区,并经野外验证,证实遥感找矿预测区内矿化蚀变发育明显,找矿意义较大。通过本次研究,说明国产高分数据的运用能够满足遥感地质矿产调查工作的要求,可为我国矿产资源战略储备提供有利的遥感技术支撑。The GF-1 remote sensing data selected for mineral resource exploration in the Dachaidam area in the northern margin of Qaidam basin was discussed. The GF-1 remote sensing image was plotted by using image processing technology in the study area. On this basis, the geological stnlcture, lithostratigraphic and iron stain alteration anomaly information in this area were extracted. Through the comprehensive analysis and study, the two remote sensing prospecting prediction areas were outlined. By the field verification, it is confirmed that the mineralized alteration was well developed. The case study result indicated that this national high-resolution GF-1 data can meet the requirement of geological survey and mineral exploration, and it provides favorable remote sensing technological sup- port for the strategic reserve of national mineral resources.
