Model and application of radon anomaly in soil of sandstone type uranium deposits in Erlian Basin
摘要
Abstract
Erlian Basin is one of the most important sandstone⁃type uranium fields in northern China. In order to get the weak minerali⁃zation data at surface and establish the direct prospecting criteria, the authors carried out measurement of areal⁃type soil radon and its daughter in the basin. According to the analysis of uranium mineralization data as well as the section and plane data, soil radon anomaly of sandstone⁃type uranium deposits can be built, i.e., radon anomalies in soil are always located in the upstream direction of uranium, with the anomaly value higher than 15 000 Bq/m3 . In general, the upper part of the deposit has the background value of radon, while the larger halos of radon are distributed in the downstream direction of the deposit. On the basis of this model, it can be inferred that Erlian Basin is characterized by fairly favorable potential of uranium mineralization. On such a basis, further prospecting targets can be delineated.关键词
