内蒙古拜仁达坝—维拉斯托银锡多金属矿床的遥感找矿研究
Remote sensing interpretation and metallogenic prediction in the Bairendaba-Weilasituo silver-tin polymetallic deposit,Inner Mongolia
摘要
Abstract
The Bairendaba-Weilasituo area in Inner Mongolia is characterized with favorable metallogenic conditions,where the silver and tin mineral resources are enriched,mineralization alterations extensively devel-oped and prominent geo-structures control ore deposits.By utilizing ASTER,Landsat-8 OLI,and DEM data,ap-plying methods such as DEM hill shading,slope analysis,high-pass filtering,and directional filtering,in combina-tion with principal component analysis and other digital image processing methods,this study finally identified a total of 329 linear structures and 4 circular structures of the Bairendaba-Weilasituo area.Additionally,ASTER da-ta and the principal component analysis method were employed to extract alteration information related to Fe3+,Al-OH,Mg-OH,carbonation,silicification,and clay alteration.Based on alteration and structural data,three prospects favorable for mineral exploration were delineated.The results indicate that structural interpretation and alteration information extraction based on DEM,Landsat-8 OLI,and ASTER data can accurately identify key structural and alteration-related exploration markers.This approach is applicable in central Inner Mongolia,pro-viding a rapid and effective method for mineral exploration and offering valuable insights for the study of silver-tin polymetallic deposits within the region.关键词
