我们在白云鄂博水磷钙钍石细脉中发现一种黑色不透明矿物。经研究,确定为水磷钙钍石的新变种——含流水磷钙钍石,为国内首次发现。 1.地质产状:该矿物产于白云鄂博群第四层变质石英砂岩中,呈浸染状分布在水磷钙钍石细脉内。细脉旁侧的变质石英砂岩产生明显的蚀变、重结晶和退色现象,局部重结晶成为油脂光泽很强的似高温脉状石英。共生矿物有水璘钙钍石、透辉石、磷灰石、
We found a black opaque mineral in the Phytagedithorite veins of the Bayan Obo water. After research, it is identified as a new variety of water-phosphorus calcium-thorium stone-containing water-phosphorus-calcium-thorium stone, which was first discovered in China. 1. Geological occurrence: The mineral is produced in the fourth layer of the Bayan Obo metamorphic quartz sandstone, was disseminated distribution in the water phosphorus calcium thorium stone vein. Metamorphic quartz sandstone beside the veins has obvious alteration, recrystallization and fading phenomenon, and local recrystallization becomes a high-temperature vein quartz with strong luster of oil. Symbiotic minerals such as calcium, thorium, diopside, apatite,
