WorldView-3影像在内蒙古苏莫查干敖包地区铀矿勘查中的应用
|
摘要
为对苏莫查干地区呈小规模展布的铀成矿带进行勘查研究,采用WorldView-3(WV-3)高分辨率影像和主成分分析、假彩色合成,对研究区内岩性、构造进行解译;利用主成分分析法及可见光近红外波段提取了铁染蚀变信息,同时也利用光谱角制图法及短波红外波段提取了黏土化蚀变信息,并进行了野外验证。结果表明, WV-3遥感影像能很好识别出研究区呈小范围展布的铀矿地质信息,有助于促进该区铀矿勘查研究。
In order to explore the small-sale uranium mineralization belt in Sumoqagan, high resolution image WV-3 was used to interpret the lithology unit and structures in the study area by Principal Component Analysis( PCA) and pseudo-color synthesis. First, the visible near infrared( VNIR) bands image were used to extract iron staining alteration by Principal Component Analysis(PCA), then the shortwave infrared(SWIR) images bands was used to extract the clay minerals information by Spectral Angle Mapper(SAM).Finally, field validation was carried out. The results show that WV-3 image can identify small size and weak geological information for uranium prospecting in the study area, which is helpful to feature uranium exploration.
