高分辨率遥感技术(包括高空间分辨率和高光谱分辨率)是新世纪以来地质勘查领域的重要新技术、新方法。本文以新疆塔里木盆地北缘巴什布拉克铀矿区和柯坪地区为例,研究了Quickbird高空间分辨率卫星遥感技术和CASI(Compact Airborne Spectrographic Imager)/SASI(Shortwave infrared Airborne Spectrographic Imager)航空高光谱遥感技术在铀矿勘查中的应用。首先,介绍了Quickbird和CASI/SASI高分辨率遥感数据的特点和处理方法;然后,分析了Quickbird高空间分辨率遥感技术在新疆塔里木盆地北缘巴什布拉克铀矿区油气还原褪色蚀变识别与空间分布规律分析中的应用,为铀矿油气还原成因研究和外围找矿方向提供重要依据;并研究了Quickbird与CASI/SASI两种高分辨率遥感技术在新疆塔里木盆地北缘柯坪地区铀矿勘查中的应用,发现了萨拉姆布拉克铀矿化带及其铀矿化蚀变空间分布特征,确定了铀矿化蚀变类型,预测了铀矿找矿靶区,为该地区铀矿勘查的新突破提供了重要依据。上述应用表明,高分辨率遥感技术在铀矿地质勘查领域可以取得很好的应用效果,值得广大遥感地质工作者今后进一步深入挖掘其应用潜力。
High resolution remote sensing technology (including high spatial resolution and hyperspectral resolution) is an important new technology and method in the field of geological prospecting in the new century. Taking the Bashibulake uranium deposit and Keping area on the northern margin of Tarim Basin in Xinjiang as an example, this paper studied the application of Quickbird high spatial resolution satellite remote sensing technology and CASI (Shortwave infrared Airborne Spectrographic Imager) Application of Remote Sensing Technology in Uranium Exploration. First of all, the characteristics and processing methods of Quickbird and CASI / SASI high resolution remote sensing data are introduced. Then, the paper analyzes the relationship between Quickbird high spatial resolution remote sensing technology and oil and gas reduction and fading alteration in the Bashibulake uranium area on the northern margin of Tarim Basin, Xinjiang The application of spatial analysis to space distribution provides an important basis for the study of genesis of uranium deposits and the prospecting direction of peripheral uranium deposits. Two high-resolution remote sensing techniques, Quickbird and CASI / SASI, are also studied in the Keping area uranium mine in the northern margin of Tarim Basin Exploration, the discovery of the Salambulak uranium mineralization zone and its uranium mineralization alteration spatial distribution characteristics, to determine the type of uranium mineralization alteration, prediction of uranium ore prospecting target area for the uranium ore New breakthroughs in exploration provided an important basis. The above application shows that high-resolution remote sensing technology can obtain good application results in the field of uranium geological exploration and it is worth the vast number of remote sensing geologists to further dig their potential applications in the future.
