摘要: 遥感地质解译和异常信息提取是遥感地质学的重要研究内容之一。为分析在江西盛源火山盆地中寻找铀矿的前景,以ALOS,SPOT5和ETM+等多源遥感数据为信息源,结合数字高程模型( DEM),对该盆地进行了遥感地质解译和遥感蚀变异常信息提取与筛选,重点提取与铀多金属矿有关的地层、断裂构造、火山机构和蚀变异常等成矿信息;并结合已有地质资料,在ArcGIS平台上开展基于遥感数据的成矿地质条件综合分析和找矿预测,提出了3个找矿有利区,为当地矿产资源勘查和资源评价提供基础数据和参考依据。Abstract: Remote sensing geological interpretation and anomaly information extraction constitute one of the important research fields of remote sensing geology. Based on ALOS, SPOT5, ETM+ and other multi -source remote sensing data, and combined with digital elevation model(DEM), the authors carried out remote sensing geological interpretation, remote sensing abnormal information extraction and selection for Shengyuan volcanic basin in Jiangxi Province, with much attention paid to the extraction of uranium and polymetallic mineralization information, such as strata, fracture, volcanic edifice and alteration information. In combination with the available geological data, the comprehensive analysis on ArcGIS platform was conducted so as to understand ore-forming geological conditions and make prospecting prediction. The results achieved by the authors can provide basic data and reference for local mineral exploration and resource evaluation.
