Theoretical System of Sandstone-Type Uranium Deposits in Northern China被引量:11
《Journal of Earth Science》2022年第2期257-277,共21页Ruoshi Jin Huajian Liu Xiaoguang Li 
The“Northern Sandstone-type Uranium Deposits Investigation Project”(Project 0108)of the China Geological Survey has led to the discovery of many new sandstone-type uranium deposits;The National Basic Research Program(973 Program)(No.2015CB453000);the National Key R&D Program of China(No.2018YFC0604200)both from the Ministry of Science and Technology of the People’s Republic of China have led to innovations in many theoretical understandings of sandstone-type uranium deposits;Under the International Geoscience Programme(No.IGCP-675),a comparative study of sandstone-type uranium deposits between China and the rest of the world has been conducted。
Many theoretical results on sandstone-type uranium mineralization in northern China obtained by the uranium research team of the Tianjin Center of Geological Survey in recent years are presented.From the source sink s...
