基于对阿尔泰和科拉半岛的伟晶岩田中的稀有金属花岗伟晶岩的多年研究,我们将后者划分成以下四种主要类型:Ⅰ、微斜长石伟晶岩;Ⅱ、钙长石—微斜长石伟晶岩;Ⅲ、钠长石伟晶岩;Ⅳ、钠长石—锂辉石伟晶岩。实际上这种划分乃是以微斜长石、钠长石和锂辉石等三种主要造岩矿物为依据的,而且只有当它们的量超过伟晶岩总体积的10—15%时,才把它们用来作为伟晶岩类型名称的命名。我们之所以选择 Based on years of research on rare-metal granitic pegmatites in the pegmatites of the Altay and Kola Peninsulas, we have classified the latter into four main types: Ⅰ. Micelphane pegmatite; Ⅱ, Micro-plagioclase pegmatite; Ⅲ, albite pegmatite; Ⅳ, albite-spodumene pegmatite. In fact, this division is based on three major rock-forming minerals such as micro plagioclase, albite and spodumene, and only when they exceed 10-15% of the total volume of pegmatite Use them for naming pegmatite type names. We chose
