GEOCHEMICAL CHARACTERISTICS OF TRACE ELEMENTS IN MAJOR MINERALS OF MIANNIN REE DEPOSIT,SICHUAN PROVINCE

Niu Hecai; Lin Chuanxian (Guangzhou Institute of Geochemistry, The Chinese Academy of Sciences,Wushan, Guangzhou 510640)  
The study on inclusion geochemistry shows that there exist magmatogenetic minerals, such as fluorite, barite, calcite in the Miannin REE deposit, Sichuan Province. The geochemical characteristics of their trace elements are different from those of hydrothermal minerals. The Miannin deposit has higher content of trace elements in fluorite than hydrothermal those. The magmatogenetic barite is rich in lithophile elements but poor in sulfophile ones.Both magmatogenetic barite and fluorite are extremely rich in volatile components. Barite and fluorite possess different REE geochemical characteristics depending on their origin. Magmatogenetic fluorite and barite crystallize in an acidic and reducing environment.
