摘　　要：鉴于遥感技术的日趋成熟,遥感信息定量/半定量分析在地质找矿应用中越来越受到重视,该文在充分收集前人地质和矿产资料的基础上,以Landsat-7ETM+遥感数据为主要数据源,对吉尔吉斯斯坦与塔吉克斯坦及其我国周边地区的线性构造进行1∶100万遥感解译,对解译出的线性构造开展了密度分析、走向分析、趋势面分析等特征研究,获得了研究区断裂构造的密度特征、走向特征和构造应力场空间分布范围等构造样式信息。据此,揭示了研究区断裂构造格局的基本类型、分布特征。综合分析研究区成矿地质背景、线性构造特征、遥感蚀变异常,初步预测了6处重要矿种的成矿有利地段。In view of the increasing maturity of remote sensing technology,quantitative and semi quantitative analysis of remote sensing information has been paid more and more attention in the application of geological prospecting.Based on the full collection of previous geological and mineral data,and the Landsat-7ETM+remote sensing data as the main data source,the1∶100remote sensing interpretation is given to fault structure in Kyrgyzstan and Tajikistan and the surrounding areas.And the style structure information of density feature,trend feature and tectonic stress distribution field is gained through the research on the density analysis,trend analysis,and trend surface analysis of the tectonic lineament interpretation.Accordingly,the basic types and distribution characteristics of fault structure tectonic pattern of study areas are promulgated.It performs comprehensive analysis of the geological background,linear structural features,and remote sensing alteration anomalies of the study area,as well as preliminarily forecasts 6important mineral mineralization zones.
