摘要
蒙其古尔铀矿床是伊犁盆地南缘铀资源量最大的砂岩型铀矿床,关于该矿床的成因机理,也一直是铀矿地质学界关注的焦点。通过对该矿床含矿地层的地球化学特征、黏土矿物特征进行分析研究,以及对黄铁矿硫同位素的分析测试,认为在铀成矿过程中有还原物质的参与,而且该还原物质与生物作用有一定关系。生物作用参与成矿可能是蒙其古尔铀矿床矿体品位较高的重要原因。
Mengqiguer Uranium mineral deposit is the biggest uranium mineral deposit on the southern margin of Yili Basin, so the formation mechanism of this deposit has always been the focus in uranium geology field. Through analysis and study on the characteristics of geochemistry and clay minerals of ore layer in this mineral deposit, and analysis and testing of pyrite sulfur isotope, that was found there were reducing substances in uranium ore-forming processes, and the reducing substances were related with biological effects. Biological effects participated in miner- alization, which was the important reason of the high ore grade in Mengqiguer Uranium Mineral Deposit.
