摘要
华阳川铀多金属矿床是一种特殊的大型铀铌铅矿床,主要矿石矿物为铌钛铀矿、方铅矿,还有少量晶质铀矿。运用电子探针分析测试技术,分析2种含硫矿物的化学成分特征;通过研究黄铁矿化学成分组成,判断其形成于中深部环境,具中高温成矿特征;而方铅矿的化学成分特征研究发现,其形成于硫逸度较低的成矿环境。
Huayangehuan uranium polymetallic deposit is a special large U-Nb-Pb deposit. The main ore minerals are betafite,galena, and a few- uraninite. Chemical composition characteristics of two kinds of sulphur containing minerals are analyzedthrough EPMA. The study of the chemical composition of pyrite, it is judged that it is formed in the middle deep environmentwith medium high temperature metallogenic characteristics. Study on the chemical composition of galena, It is formed in themetallogenic environment with lower sulfur fugacity.
