遥感在准噶尔盆地砂岩型铀矿成矿分析及预测中的应用

Application of Remote Sensing Technique in Sandstone Type Uranium Deposit Metallogenic Condition Analyses and Regional Prognosis

新疆准噶尔盆地是我国“九五”期间砂岩型铀矿找矿工作的重点地区之一。１９９４年—１９９５年我所应用遥感技术方法，结合综合地质资料，通过ＴＮ（ＮＳＳ）图像计算机信息处理、解译及野外验证等工作，在该盆地（东准、北西准地区）开展了１∶２０万铀矿遥感地质调查，完成工作总面积约１５．５万ｋｍ２。获得了大量、丰富的地质构造及铀成矿信息，深化了对盆地地质构造背景和铀成矿条件的认识，建立了层间氧化带型铀矿遥感找矿模式（判据），划分出铀矿远景预测区１０片，为该盆地进一步铀矿普查勘探选区提供了新的依据。本文重点论述了图像处理方法、盆地遥感地质特征、铀矿遥感地质找矿模式（判据）及远景预测等内容。

Zhungeer basin in one key area of sandstone type uranium deposit prospecting ore work during the ninth five year plan in Xinjiang province. Our institute makes the uranium de posit remote sensing geological examination 1: 20 0000 by use of renote sensing technique,generaligzation geological data,TN(NSS) image computer information processing,interpretation and field check during 1994- 1995. A work are a of 155 000 km￣2 is finished. It is supplied new foundations for selecting a are a of further uranium deposit reconnaiss ance survey and pro8Pecting in basin to get a lot of information about geological structure and uranium metallogenesis deepen the knowledge of basin geological structure backgroun and uranium metallogenic condition,set up remote sensing prospecting ore model of interlager oxidation zone type uranium deposit,divide ten uranium minerogenetic prospecting provinces. This paper discusses emphatically image processing method,basin remote sensing geological characteristics the model of remote sensing geological uranium prospecting ore and prospecting prognosis.
