本文按照成因分类对印度的原子能矿物原料作简要介绍。少量的同生放射性矿物产在几个前寒武纪的花岗岩和伟晶岩体中和一些正长岩中。许多伟晶岩是绿柱石的重要来源,其次是锂云母的东源,只有一些伟晶岩含有放射性矿物的小矿囊。高温及低温热液后生矿化作用产于前寒武纪的沉积变质岩中并常常伴随着元古代以后的花岗侵入岩。重要的铀矿床都分布在比哈尔的辛弗胡姆铜矿带中。印度半岛的沉积建造主要是含钍的;在极少的几个地方曾报导过有很少量的铀偶而出现,倒如某些长石砂岩、红土、煤、磷质结核等。古贾腊特的土瓦温泉中镭的不断补充问题,本文也提出讨论了。沿着印度2000里长的海岸分布的独居石砂矿床和某些内陆砂矿本文也作了描述。
In this paper, according to the classification of causes of India’s atomic energy mineral raw materials for a brief introduction. Small amounts of syngenetic radioactive minerals are found in several Precambrian granites and pegmatites and in some syenite. Many pegmatites are an important source of beryl, followed by the eastern source of lepidolite, with only some pealoids containing radioactive minerals. The high-temperature and low-temperature hydrothermal meta-mineralization occurs in Precambrian sedimentary metamorphic rocks and is often accompanied by granitic intrusions after Proterozoic. Important uranium deposits are distributed in the Symphung copper belt in Bihar. Sediment construction in the Indian Peninsula is predominantly thorium; in rare places it has been reported that rare amounts of uranium occur occasionally, such as some feldspar sandstone, laterite, coal, and phosphorus-containing nodules. The constant replacement of radium in the Tuva Spa in Ancient Jar’at is also discussed in this paper. The monazite deposits and some inland ores distributed along the long coast of India in 2000 are also described in this article.
