[en] Through the study of aeroradiometric and aeromagnetic characteristics of five known sandstone type uranium deposits in the southern margin of Yili basin, it is emphasized that anomalies of four parameters such as uranium wide channel in downward window (Udw), uranium narrow channel in upward window (Uu), uranium wide channel in upward window (Uuw) and uranium narrow channel in downward window (Ud) are direct indicators for sandstone type uranium deposit. According to the discussed correlation between aeroradiometric information, the author points out that aeroradiometric correlation analysis is not a suitable method for the prognosis of interlayer oxidation zone type uranium deposit, but the negative correlation areas of K and Th delineated by correlation analysis is the favorable occurrence location for paleochannel sandstone type uranium deposit. After extracting weak magnetic anomalies, it was put forward for the first time that covered oxidation zone can be delineated by the distribution range of weak magnetic anomalies. Aeroradiometric and aeromagnetic computer prognosis models were established for sandstone type uranium deposit. Metallogenetic prognosis was carried out in the whole Basin. With this model, 14 pieces of prospective areas were delineated, so as to further advance ground geophysical survey, and expand prospecting achievements in the Yili basin. In a word, aeroradiometric and aeromagnetic information still play an important role in prospecting in-situ leachable sandstone type uranium deposit. (authors)

[en] The paper presents the foundational principle of quantitative predication for sandstone type uranium deposits in Russia. Some key methods such as physical-mathematical model construction and deposits prediction are described. The method has been applied to deposits prediction in Dahongshan region of Chaoshui basin. It is concluded that the technique can fortify the method of quantitative predication for sandstone type uranium deposits, and it could be used as a new technique in China. (authors)

[en] Based on the airborne radioactive and aeromagnetic data of the Zhongchuan rock mass group in West Qinling Mountains, the boundary of the rock mass is identified with the boundary enhancement technique, and the characteristics of its airborne radioactive anomalies and aeromagnetic anomalies are analyzed referred to the geological condition. This paper compared the aeromagnetic and airborne radioactive characteristics, a deep research on the uranium deposits and gold deposits have been done using the multiple parameters technique. Besides, this paper summarized the similarities and differences of the uranium deposits and gold deposits in the spatial and temporal distribution and aeromagnetic and airborne radioactive characteristics. Overall, the favorable location of uranium prospecting in the area of the Zhongchuan rock mass is where the uranium increment, the uranium variance and the uranium content all have higher values, besides magnetic field gradient zone is obvious, while the favorable location of gold prospecting is where the potassium increment, potassium variance and thorium variance all have higher values, besides the negative magnetic field or gradient zone of the aeromagnetic ΔT residual anomalies is obvious. Finally, the prospecting sites of gold deposit and uranium deposit is delineate in the Zhongchuan rock mass group, it has favorable directions for further ore-prospecting of this area. (authors)

[en] The information of the predecessors research was collected and sorted to analyze the uranium mineralization conditions in Xuemisitan area in the northwest of Xinjiang. It was believed that the uranium mineralization in this area was closely related to the tectonic environment, strata and volcanism, ore-controlling structures and the uranium source. By combining the feature of known uranium deposits and the field geological survey result, the distribution regularity of uranium was summarized and 6 First Level and 11 Second and Third Level prospecting areas were delineated in the study area for the future uranium exploration.
