【摘要】 灵丘地区是晋东北重要的铜银多金属矿集区,分布有支家地、刁泉等大型银铜多金属矿床。文章以美国Landsat-7卫星的ETM数据为遥感数据源,展开了灵丘地区约2000 km2范围的遥感找矿异常信息研究,解译出线性构造59条,环形构造9个。采用"主成分分析"法提取出铁化蚀变与泥化蚀变。结合地质分析,厘定铁染蚀变及遥感线性、环形构造信息为主要遥感异常找矿标志,并圈定找矿远景区5处。更多还原

【Abstract】 The Lingqiu region is an important copper,silver polymetallic mineralization area in northeastern Shanxi,where some large- sized copper,silver polymetallic deposits such as Zhijiadi and Diaoquan distributed. The extraction of the remote sensing abnormal information were conducted in a total area of 2000 km2in the Lingqiu region based on ETM data from USA Landsat- 7. A total of59 linear structures and 9 ring structures were interpreted. The iron alteration and argillization alteration were extracted by applying the principal component analysis. In combination with geological analysis,the remote sensing iron alteration,the linear and ring structures were determined as the main prospecting criteria,and 5 prospecting areas were outlined.更多还原
