摘　　要：利用ETM图像数据作为信息源以及光谱波谱理论作为理论基础,同时采用单波段图像分类彩色合成图像法,增强和突出与铜铅锌多金属矿成矿有关的控矿构造、热液蚀变带和源矿层的遥感影像的标志性特征。提取恩施白果坝地区铜铅锌多金属矿化蚀变信息,综合圈定遥感矿化蚀变信息异常范围,并进行遥感找矿应用,经过野外实地考查验证,发现麓池塘等铜铅锌多金属矿蚀变带,获得了良好的地质找矿效果。Based on the ETM image information source and the wave spectrum theory,the single-band image classification and color synthetic image method is used to enhance and highlight the landmark features of remote sensing images of ore-controlling structures,hydrothermal alteration zones and source beds related to copper-lead-zinc polymetallic mineralization.In this paper,the information of copper,lead and zinc polymetallic mineralization and alteration in Baiguoba area of Enshi is extracted,the abnormal range of remote sensing mineralization and alteration information is delineated comprehensively,and the application of remote sensing in prospecting is carried out.Through field investigation and verification,the alteration zones of copper,lead and zinc polymetallic deposits such as Luchitang are found,and good geological prospecting results are obtained.
