摘　　要：在内蒙东部赤峰地区小井子一带，开展遥感地质找矿应用研究，首先对ETM＋数据进行了图像几何校正、影像融合、假彩色合成等基础影像处理工作；之后对工作区进行构造解译，对包括线性构造、菱形构造、环形构造等与成矿有关的空间信息进行提取；以及利用ETM＋的1～5，7等波段几何校正数据进行了蚀变异常提取工作，包括褐铁矿化蚀变异常，含羟基和碳酸盐化蚀变异常。最后结合地质、矿产、化探资料，优选4处遥感找矿靶区，为野外工作部署提供参考。Remote sensing technique is used for geological exploration in Xiaojingzi area, Chifeng, eastern Inner Mongolia. The ETM＋ data acquired in 26th June 2000 is fist processed by geometric correction, image merging and false color composite et al. , and then spatial information （including linear structure, rhombic structure and annular structure, et al. ） is extracted. Geometric correction data from band 1 - 5 and 7 of ETM ＋ is used for extracting alteration anomaly including limonitization, OH - and CO32- bearing alteration. Four exploration target is proposed by synthesizing geology, mineral resources, geochemical exploration data with remote sensing data, which provide useful information for the future prospecting works.
