摘要
REE geochemistry of 4 groups of samples (the regional stratigraphy, ore-hosting rocks, calcites and uranium ores) were analyzed by using ICP-MS method to investigate the genesis of the Shazijiang uranium ore deposit in northern Guangxi, China. It is indicated that ore-hosting rocks and regional strata are of common sedimentary source of the continental crust. In addition,uranium ores are characterized by highest ΣREE contents (ΣREE=259.88×10-6~869.31×10-6) and ΣREE contents correlating positively with uranium ores grades, which is regarded as a clue to simultaneous transportation of REE and U. Negative Ce anomalies of uranium ores (except for two uranium black samples) were most probably resulted from oxidation condition.
