摘　　要：天绘卫星是我国新发射的卫星,有蓝色、红色、绿色、近红外4个波段,空间分辨率为10m,可以完成遥感地质应用。笔者选择新疆雪米斯坦火山岩带西段作为研究区,利用天绘卫星数据进行了地质研究,包括各类火山岩层的识别和划分、断层识别、含铁蚀变矿物的提取等,并进行了野外地质验证。研究表明,天绘卫星遥感数据能够很好识别出多种火山岩成矿要素,在地质找矿领域具有很好的应用潜力。Tianhui satellite is a new Chinese Satellite launched on December 24.2010,the sensor is designed with four bands in the VNIR spectral range with a 10 mspatial resolution and 60 km swath width which can be used for geological application.In this paper,rocks in the west of Xuemistan volcanic belt in Xinjiang was studied with the high-spatial resolution Tianhui remote sensing data,the study included lithologic mapping,detection and delineation of faults,detection of Ferric and ferrous alteration rock and field validation.The studied results shew that remote sensing data of Tianhui satellite can identify the metallognic factors for volcanic type uranium deposit and has good potential in mineral resource exploration.
