Geochemical Characteristics of U-Nb-REE Minerals From Huayangchuan U-polymetal Deposit in Shaanxi
摘要
Abstract
Huayangchuan U-polymetal deposit is located in Xiao Qinling region,with a wide variety of ore minerals and a complex formation sequence.There may be multiple stages of U-Nb-REE mineralization,and the genesis need to be clarified.Based on minerals sequence,detailed geochemistry study on major and trace elements compositions of U-Nb-REE,ore minerals has been carried out by using in-situ microanalysis of EPMA,Laser Raman,and LA-ICP-MS.REE distribution patterns of amphibole in ore veins and carbonate are similar,and REE compositions of monazite,apatite,and allanite are consistent with the characteristics of minerals in carbonate,indicating that the fluid related to U-Nb-REE mineralization is a post carbonatite ore-forming fluid.关键词
