By leveraging the remote sensing technology, we have delved into the remote sensing prospecting model for typical uranium mining area along the Sino-Russian Economic Corridor. According to the remote sensing interpretation results of the basic geology along the Sino-Russian Economic Corridor, we have analyzed and summarized the remote sensing geological features of the structure, stratum and rock mass in this area. Moreover, by providing the remote sensing interpretation of basic geology in the Russian Streltsovsky typical hydrothermal uranium mining area based on the data of the domestic GF-1 satellite, we have made conclusive analysis on the characteristics of its ore-controlling elements and preliminarily summarized the remote sensing geological prospecting model for typical volcanic hydrothermal uranium deposits in this area. By using the remote sensing prospecting model, we have delineated three favorable ore-forming sections, which provides an important basis for regional mineralization prediction and the delineation of favorable ore-forming areas, and helps seek such deposits in the same or similar areas.
Practices of sandstone-type uranium exploration in recent years in China indicate that the uranium mineralization
alteration information is of great importance for selecting a new uranium target or prospecting in outer area of the known
uranium ore district. Taking a case study of BASHIBULAKE uranium ore district, this paper mainly presents the
technical minds and methods of extracting the reduced alteration information by oil and gas in BASHIBULAKE ore
district using ASTER data. First, the regional geological setting and study status in BASHIBULAKE uranium ore district
are introduced in brief. Then, the spectral characteristics of altered sandstone and un-altered sandstone in
BASHIBULAKE ore district are analyzed deeply. Based on the spectral analysis, two technical minds to extract the
remote sensing reduced alteration information are proposed, and the un-mixing method is introduced to process ASTER
data to extract the reduced alteration information in BASHIBULAKE ore district. From the enhanced images, three
remote sensing anomaly zones are discovered, and their geological and prospecting significances are further made sure
by taking the advantages of multi-bands in SWIR of ASTER data. Finally, the distribution and intensity of the reduced
alteration information in Cretaceous system and its relationship with the genesis of uranium deposit are discussed, the
specific suggestions for uranium prospecting orientation in outer of BASHIBULAKE ore district are also proposed.
