作者从调查区花岗伟晶岩中采得了一些含铀及希有元素矿物。经过对矿物物理性质、化学成分、差热和X射线粉晶分析鉴定,肯定的含铀矿物为富铅钛铀矿、钶钛铀矿和易解石;经过矿物的α径迹乳胶照相观察,初步了解了矿物中铀和钍的存在状态;从伟晶岩中矿物的绝对年龄测定,可肯定这些矿物形成于1890±90百万年以前。
The authors collected some uranium-bearing minerals from the granitic pegmatites in the survey area. After the physical and chemical properties of minerals, chemical composition, differential thermal and X-ray powder analysis identified, the sure uranium-bearing minerals are lead-rich titanium-bearing uranium deposits, uranium titanites and calcite; A preliminary understanding of the existence of uranium and thorium in minerals is present; from the absolute dating of pegmatites in pegmatites, it is confirmed that these minerals formed 1890 ± 90 million years ago.
