内蒙古大营铀矿区高光谱遥感蚀变信息提取

Extraction of Hyperspectral Remote Sensing Alteration Information in Daying Uranium Deposit Inner Mongolia

为解决遥感勘测技术在大营铀矿区应用的问题,基于大营铀矿区的Hyperion卫星高光谱遥感影像数据,以及油气微渗漏理论思想,提出重点提取出含铁离子、碳酸盐、粘土矿物等典型矿化蚀变信息的研究方法,并将填图结果与内蒙古大营铀矿区的基础地质、地球物理和地球化学等资料予以对比分析。结果表明,所提取出的多数矿化蚀变信息能作为该地区铀矿勘查工作中的重要找矿标志。

In order to solve the problem of remote sensing technology in the application of Daying uranium mine, on Daying, using the theory of oil and gas percolation, we proposethe research method that is important to extract the ferrous ion, carbonate, clay minerals typical mineralization alteration information. And it is used to contrast the mapping results and the basic geology, geophysical and geochemical data in Daying uranium. The results show that the majority of extracted mineralized alteration information can be used as an important prospecting mark in uranium exploration of this region.
