通过电子探针研究,在内蒙巴音戈壁盆地塔木素砂岩型铀矿矿石中发现了硒铅矿、白硒铁矿、硒铜蓝、硒铜镍矿、斜方硒铜矿等5种硒的独立矿物,这些硒的独立矿物往往呈细粒状、蠕虫状分布在黄铁矿与石英、长石的边缘或矿物的裂隙中。硒铅矿、白硒铁矿等硒矿物是典型的中低温热液矿物,这些矿物的发现表明塔木素铀矿床曾经历中低温热液阶段。
Through electron probe study, five kinds of selenium, selenite ore, selenium copper blue, selenite copper nickel ore and orthorhombic selenium copper mine were found in the Tarim sandstone-type uranium ore of Bayingeobi basin in Inner Mongolia. Of the independent minerals, these selenium independent minerals tend to be fine, worm-shaped distribution in the pyrite and quartz, feldspar edge or mineral cracks. Selenium minerals, such as selenium and selenite, are typical low and intermediate temperature hydrothermal minerals. The discovery of these minerals indicates that the tarsulinum uranium deposit experienced a mid-low temperature hydrothermal phase.
