摘要
通过遥感标准影像图制作、地质构造的解译推断和遥感蚀变信息提取等研究,将我国大陆划分为8大遥感特征区,对多条巨型控岩控盆断裂的分布特征进行修正和补充,在多个预测工作区中发现了隐伏断裂、火山机构、岩溶漏斗等,通过分析预测区内构造斜坡带和局部排泄带分布、岩体和断裂带的蚀变等成矿条件,结合铀矿地质信息预测了92片有利成矿区。
Through developing stand remote sensing image,interpreting and inferring geological structure and extracting alteration information,we have divided China mainland in 8 feature regions,corrected and replenished several huge fractures which controlled the spatial pattern of magmatism and sedimentary basin in China,found out the shaded faults,volcanic structures and karst funnels which were related to regional uranium mineralization,identified the structural slope and local discharge zone,alteration feature of granite plutons and fracture zones which control the uranium mineralization.By combining remote sensing information with uranium geology information,we have predicted 92 favor areas in China mainland for further uranium prospecting.
