查明在不同成份岩石内化学元素的原始分布规律是岩浆作用地球化学的各种问题中的最重要问题之一。目前铀含量资料最多的是花崗岩类酸性岩石。对基性、超基性和碱性岩石的研究则差得多。不同作者[1—4]所测得的花崗岩类岩石中的平均均铀台量为3—4伽玛/克岩石,但在不同地区(天山[5—8],高加索[9],阿尔泰[10—12],图瓦[13],乌克兰[14—15],美国[16,17],德国[18],)对侵入杂岩和岩体的研究说明其变化范围较大(从3—8伽玛/克岩石,而高伽索、阿尔泰和图瓦的花岗岩类甚至到
It is one of the most important problems in the various problems of magmatic geochemistry to identify the original distribution of chemical elements in rocks of different compositions. At present, the most uranium content is granite acidic rocks. Studies of basic, ultrabasic, and alkaline rocks are far less common. The average amount of uranium in granitic rocks measured by different authors [1-4] is 3-4 Gamma / g rock, but in different regions (Tianshan [5-8], Caucasus [9], Altai [ The study of intrusive complexes and rock mass shows a wide range of variation (from 3-12), Tuva [13], Ukraine [14-15], the United States [16,17], and Germany [18] 8 Gamma / gram of rock, while Granas of Gausso, Altai and Tuva even went
