摘要
利用Landsat-7 ETM+数据,结合洞中拉-亚贵拉矿集区1∶25万地质、矿产、化探等综合资料,建立了该区矽卡岩型铅锌多金属矿床综合信息找矿模型:对研究区的断裂、地层、岩体、化探-遥感异常等成矿信息的有利度进行分析,建立了有利于成矿的单个变量和组合变量空间数据库;利用GIS空间分析和信息量法进行综合定量成矿预测,圈定了7个成矿远景区。
Based on integrated research for Dongzhongla-Yaguila ore concentration area on 1∶250 000 geology,minerals,geochemical exploration,remote sensing and etc,the model of lead-zinc polymetallic ore deposits is built from Landsat-7 ETM＋.The results of fault,stratum,rock mass,geochemical and remote sensing anomalies beneficial degree are shown.The spatial database of single and composed variable are established.Through comprehensive and quantitative prediction,7 miner genetic prospective areas are delineated by GIS spatial analysis and information method.
