摘要
本文深入探讨了在覆盖区开展遥感地质研究的思路、方法和途径。讨论了如何运用多种遥感数据处理（包括陆地卫星遥感微弱信息处理及科学试验卫星像片二次开发）、多参数特征提取及立体显示与模拟等方法，结合各种资料综合解译，破译覆盖层下部地质层体信息和成矿预测。并以伊犁盆地为例，详细阐述了如何解译各种控矿因素；圈定控制铀矿分布的隐伏产铀建造；鉴别与沉积环境及矿化富集有关的隆起和凹陷；识别控制盆地形成和发展的断裂（包括隐伏断裂）构造；解译与铀矿化富集和保存有关的相对稳定区和相对活动区。通过影像处理和解译，成功地确定了控制层间氧化带分布和矿床定位的局部排泄带，识别了远景地段的影像特征，为该区进一步铀矿普查与勘探优选了有利靶区，取得了明显的验证效果。
The thinking, method and channel of remoto geological research in the covered areawere discussed in the paper. The application of dear with the multiform remoto data (including the weak information of land-satellite and the second exploit of scientific experimental satellite image), collectionof multipsrameters feature and the method of steroscopicdisplay and modelling were discussed with the synthetical explanation of various data toget the informations of geological bodies under the covered beds and the informations ofmetallogenic prognosis. Take the Yili basin as the sample,authous interpret how to explainthe various ore-control factors; to block out the buried uranium-bearing formations whichcontrol the uranium ore-body distribution; to distingush the uplift and depression that related to the sidementation environment and enrichment of mineralization; to judge the faultstructure (including buried fault) that controls the basin forming and development; and toexplain the relative stable and active regions that related with the enrichment and preservition of uranium mineralization. Through the image handling and explaination, the locak excreted belts that controlled the distribution of interlayer oxidized zone and deposit setshave been successfully confirmed. The images feature of prospective region have also beendistingushed, and the useful regions for the futher uranium reconnaissance and explorationcould be selected. The research work has got a obvious confirmation result.
