摘　　要：将遥感技术应用于1:5万区域矿产地质调查,可以充分利用遥感技术宏观、综合、快速和多层次的技术优势,对广阔区域进行遥感区域地质和矿产地质调查研究,查明地质体的分布规律、矿化蚀变带的分布范围,为编制成矿规律图和进行矿产预测提供资料。本文介绍了内蒙古古朔根乌拉地区1:5万矿调项目遥感影像的处理与制作、工作区遥感地质特征,以及遥感提取羟基蚀变异常和铁染蚀变异常的整个过程,并结合地质特征和矿(化)点分布情况对提取的遥感蚀变异常进行了初步评价。由于工作区第四系和植被覆盖严重,1:5万遥感地质解译对1:5万区域矿产地质填图起到了指导作用,提取的遥感蚀变异常与已知矿(化)点套合良好,是重要的找矿信息。The remote sensing techniques have many applications in 1：50000 Regional geological survey. We use its macroscopic, synthesize, fast, multilevel and other technological advantages. Remote sensing regional geology and Mineral geological survey to the vast region have been completed. Judging by the research, we find out the distribution rules of the geologic body and distribution range of mineralization alteration zone. These researches can provid data for us to draw up metallogenic map and complete metallogenic prognosis. This paper expounds the whole process in the application of remote sensing technique in 1：50000 Regional geological survey in Gu shuogenwula area, Inner Mongolia. The whole process includes the processing and production of the remote sensing image, interpretation of remote sensing geological features in workspace, the whole process to remote sensing extract Hydroxy alteration and Iron stained alteration anomaly,and make the preliminary evaluation of the extraction in remote sensing alteration anomaly combine with the geological features and mineralization distributions of this area. Many parts of the work areas are covered by Quaternary System and Vegetation, 1：50000 Remote sensing geological interpretation work plays a guiding role for 1：50000 Regional geological survey, Remote sensing alteration anomalies we extracted are in good correlation with the known mineralized spots, most information is mineralization and alteration information, all of these provide us important information for ore prospecting.
