Indicator Elements Combination’s Characteristic and Genesis of Four Types of Uranium Mineralization in China

China uranium mineralization in accordance with different metallogenic host rocks are mainly divided into four types: granite type uranium mineralization, volcano rock type uranium mineralization, the carbonate-siliceous-politic rock type and sandstone type uranium mineralizations, four types of uranium mineralization is due to different genesis and metallogenic environment, the indicator elements also have bigger difference. In this paper, through the national uranium resources potential evaluation project research results, describes characteristics of indicator elements of four types uranium mineralization, and from the perspective of element geochemistry, analyzes causes of the indicator elements combination.
