TM、SAR、放射性能谱资料在砂岩铀矿成矿地质条件分析及找矿中的应用

THE APPLICATION OF TM AND SAR AS WELL AS AIRBORNE RADIOACTIVE DATA TO PROSPECT FOR URANIUM DEPOSIT OF SANDSTONE TYPE

在铀成矿理论指导下，运用彩色空间变换和比值合成方法对ＬａｎｄｓａｔＴＭ、ＪＥＲＳ－１ＳＡＲ及航放数据进行综合处理，有效地提取了与砂岩型铀矿成矿有关的各种地质信息，如铀源条件、补给－径流－排泄等水文地质条件及矿化蚀变信息等，在此基础上，对本区成矿远景进行了评价，并预测了远景地段。

Based on the theory of uranium deposit of sandstone type, the methods of IHS transformation and band ration were used in order to extract the information, such as uranium source, alimentation-runoff-discharge system as well as alteration from the Landsat TM, JERS-1 SAR and airborne radioactive data which is related to the formation of uranium deposit. At last, the author evaluates the metallogenetic prospective and forecasts a potential area of interest.
