摘要
本文通过对山西灵丘县梨园金矿矿区及其外围地区的ETM+图像遥感蚀变信息进行提取,采用ETM+7(R)+ETM+4(G)+ETM+1(B)进行遥感图像的RGB融合,分别提取铁染蚀变信息和泥化蚀变信息,分析结果表明研究区内蚀变信息不强,但研究区外围狼牙山一带蚀变信息较强,上述结论对今后该地区的找矿工作具有一定的指导意义。
By analyzing the ETM+image remote sensing alteration information of Liyuan Dold Deposits mining area in Lingqiu County,Shanxi Province,and its peripheral areas,and by using the ETM+7(R)+ETM+4(G)+ETM+1(B)for remote sensing image RGB fusion,respectively Iron alteration information and argillization information is extracted.The results show that the alteration information of research area is not strong,but the alteration information of peripheral area in Langya Mountain is stronger.The conclusion has a certain guiding significance for the prospecting work in the future.
