摘要
Abstract
The Enhanced Thematic Mapper image (ETM+)was used to study uranium metallogenic ele-ments in Qinglong area,Hebei Province.The image were first enhanced with color composition and image filtering technology,and linear and circular structures were identified by visual interpretation.The iron stained and hydroxy alteration information were extracted with Principal Component Analysis (PCA)and threshold segmentation.The relation of linear and circular structures,alteration information, airborne radioactive anomaly and uranium occurrences and deposit was comprehensively analyzed with GIS ,and three metallogenic prospective areas were finally predicted in Qinglong area.关键词
