为了探索稀土、稀有元素的矿化富集规律,一九五七年以来曾经就花岗伟晶岩和花岗岩类型的划分及其时间、空间、岩性等演化问题进行过多次讨论。通过这些讨论,可以看出花岗岩、花岗伟晶岩的演化是整个地壳演化的一个组成部分。在地壳演化过程中,物理化学和地质条件的不断变化,必然导致花岗岩、花岗伟晶岩中矿物种类和矿物组合的变化。根据在
In order to explore the laws of mineralization and enrichment of rare earths and rare elements, discussions on the division of granitic pegmatites and granitoids and their evolution in time, space and lithology have been discussed since 1957. From these discussions, we can see that the evolution of granites and granitic pegmatites is an integral part of the entire crustal evolution. In the process of crustal evolution, the ever-changing physical chemistry and geological conditions inevitably lead to changes of mineral species and mineral assemblages in granites and granitic pegmatites. According to
