Typical applications of airborne hyper-spectral remote sensing technology in uranium exploration:A case study of Xuemisitan area,Xinjiang
摘要
Abstract
Hyper-spectral remote sensing technology is an important new technology and method in the field of geological and mineral exploration.In recent years,airborne hyper-spectral remote sensing technology and its application to uranium exploration have received attention and extensive research in nuclear geological system.On the basis of analyzing the previous uranium predict ideas from geology,geopyhsics and geo-chemistries in Xuemisitan area,Xinjiang,this article elaborated on the new uranium exploration idea and its typical application effects using CASI/SASI airborne hyper-spectral data.Firstly,an in-depth analysis of the airborne hyper-spectral remote sensing characteristics of the Baiyanghe uranium deposit and its surrounding areas were conducted.Key elements for uranium prospecting,such as the regional hydrothermal activity center and the alteration of H-Al sericite related in uranium mineralization,were proposed.An innovative idea and approach were proposed for uranium exploration through airborne hyperspectral remote sensing;which includes"identification of regional hydrothermal activity centers-determination of the area of developing airborne hyperspectral alteration combination related with uranium mineralization-selection of composite areas of alteration,structure,favorable lithology,and other elements".Then,based on the airborne hyperspectral remote sensing information,the uranium prospecting areas were selected and the field investigations were carried out.As a result,a new uranium mineralization anomaly was discovered.Detailed surface radioactive measurements,geological surveys,trench exploration,and other investigations were conducted on the anomalous areas.Research has shown that newly discovered uranium mineralization anomalies exhibit distinct airborne hyperspectral remote sensing features,strong surface uranium anomalies,well-developed controlling fault structures,favorable geological environments,and promising uranium exploration prospects in deep.This article is the author's in-depth thinking and mining on how to fully using hyperspectral remote sensing technoglogy in uranium exploration,and improve the application effect to better serve uranium exploration.It is also a good example of using hyperspectral remote sensing technology to directly search for hydrothermal minerals in areas with good surface rock exposure,hoping to provide reference for geological workers to innovate and apply geological exploration methods.关键词
