嗜酸氧化亚铁硫杆菌在沥青铀矿石浸出中的作用
A pitch-pitchblende-pyrite vein was firstly observed in the ore from the Sawapuqi uranium deposit in Xinjiang through the study of ores by using polarization-microscope,fluorescence-microscope and electron-probe.
通过对新疆萨瓦莆齐铀矿床中铀矿石的偏光、荧光反射显微镜研究和电子探针分析测试,首次在矿石中发现沥青-沥青铀矿-黄铁矿脉,对脉体中沥青、沥青铀矿、黄铁矿的空间关系研究表明,沥青铀矿和黄铁矿均受沥青脉的控制,是脉体中还原能力较强的轻烃类物质与周围环境相互作用的产物,矿物中的铀和铁元素主要来自周围环境而非脉体本身。
A densely zoned rhythmic intergrowth of coffinite and pitchblende was found in a granite hosted uranium deposit in SE China.
