| Abstract: | Abstract:The Huashan granitoid body in Guangxi formed in the Yanshanian, petrographycally as medium-coarse biotite granite. The research of major elements, trace elements and rare earth elements indicate that it is characterized by rich alkaline, high potassium, low phosphor, high TFeO/ MgO and
high contents of high field-strength elements (HFSE) such as U, Th, Pb, Nb, and Ta and evident negative anomalies of Ti, Sr, P and Ba. On the REE diagrams it shows apparently negative Eu anomalies, significant differentiation of LREE, and higher contents of LREE than HREE. The lithogeochemical
characteristics of the Huashan granitoid body indicate it is the A-type granite. The Huashan granitoid body is rich in U with U=18.34×10-6 on average,
having similar lithogeochemical characteristics, hydrothermal alteration and U mineralization, displaying a good uranium-bearing potential. |
