摘　　要：鄂西-湘西地区铅锌矿是上扬子地块低温热液矿床的重要组成部分,与地层和构造密切相关。以Landsat-7 ETM+融合图像为数据源对该地区地层和构造遥感解译发现:鄂西北部地区铅锌矿主要分布在环形构造的周缘;湘西地区铅锌矿主要分布在南部环形构造西侧近北东向的线性构造影像区交汇处;鄂西、湘西交界地区铅锌矿主要分布在北东向长条状绿色调影像区。在此认识的基础上,结合区域1∶20万铅锌地球化学异常资料,圈定出了6个铅锌矿找矿遥感预测区。The lead-zinc deposits in west Hubei and west Hunan areas are important epithermal deposits of up-per Yangtze block.The deposits are closely related to strata and structure in the area.Using the fused image by Landsat-7 ETM＋data,the remote sensing interpretation of the strata and structure are carried out in the area, and the lead-zinc deposits in the north of west Hubei mainly distribute around the circular images.The lead-zinc deposits in west Hunan distribute at the junction of linear images in the west of the circular image in the south part.The lead-zinc deposits at the intersection of the two provinces distribute in the area of green banded image.Based on above finding,the prognostic areas for the lead-zinc deposits are delineated combined with the regional geochemical anomalies of Pb and Zn.
