UPto now, the interpretation of remote sensing concealed geology informa- tion in Quaternary covering area is still a tough problem to be solved in remote sensing geology. This paper is aimed at discussing how to utilize satellite image processing method combining with multiple information interpretation to extra- ct useful geological information covered by heavy Quaternary sediment. By means of comprehensive interpretation of image signature, "prospective information", geomorphic features and drainage pattern, we can successfully differentiate the image features between the covering strata and the buried terraine and ascertain ore-controlling factors. Taking the Yili basin for example, the faults(including the buried faults), which control formation and development of the basin,have been interpreted. The Productive uranium formations,which dominate uranium distribution,have been delineated. The uplift and subsidence, which are related to sedimentary environment, have been discriminated. The stable area and active block, which are connected with uranium concentration and preservation, have been discerned. The results have proven to be useful, for revealing the distribution regularities、guiding uranium reconnaissance and exploration further in the covering area.
