| Abstract: | 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. |
