It is found that there is a co-relationship between the boron isotope and chemical composition of magmatic tourmaline: the δ〓B value increases with increasing Al and Li in Y-site of tourmalines. The low δ〓B values (-41. 1～-39. 01‰) in Altay No. 3 pegmatite, which is one of the lowest values found by now, imply that non-marine evaporites might exist in magma source, or the pegmatitic magma had been assimilated by them during its intrusion and emplacement.
阿尔泰3号伟晶岩最初形成的结构带中电气石的B同位素组成是目前所发现的最低值之一(-41.11～-39.01‰)，指示形成伟晶岩脉的初始岩浆可能由含非海相蒸发岩的泥质岩经变质深熔作用形成，或是伟晶岩岩浆在上侵定位过程中同化了含非海相蒸发岩地层的结果。
-
It is explained that the large fractionation of boron isotope observed in tourmalines of Altay No. 3 pegmatite is resulted from the fractionation of boron isotopes between tourmaline and muscovite, and also tetraborate, in combination with the fractionation between fluid and melt phases.
本次研究利用电气石-白云母和电气石-四硼酸盐矿物间的同位素分馏以及熔体相-流体相间的同位素分馏，合理解释了阿尔泰3号伟晶岩脉电气石B同位素分馏过程，并首次获得伟晶岩形成、演化过程中B同位素组成演化的全程图谱。

5 Ma. These isotopic data provide important evidence for solving the problem of whether there occurred Caledonian mineralization and further support the view that pegmatites and pegmatite rare metal-muscovite deposits in the Altay area were not only formed in the Hercynian.
本次工作通过野外调查和同位素年代学研究，首次在阿尔泰西部的也拉曼大型含绿柱石白云母矿床(426±13Ma)、阿尔泰中部的那森恰大型含绿柱石白云母矿床(447.7±0.4Ma)及阿尔泰东部的青河拜兴白云母伟晶岩脉(436.0±0.5Ma)中获得了可靠的加里东期成矿的同位素年代证据，从而为解决是否存在加里东期成矿的问题提供了重要依据，并进一步认识到阿尔泰地区的伟晶岩及伟晶岩型稀有金属-白云母矿床并非只形成于海西期。

felsite：霏细岩
细晶岩与霏细岩(felsite)易混淆,其区别是细晶岩为全晶质,细晶结构,矿物似砂糖粒状. 霏细岩具隐晶质结构,瓷状断口. 伟晶岩(pegmatite)是粗粒或巨粒结构的脉岩,各种成分的侵入岩都有相应成分的伟晶产出,但分布最广的是花岗伟晶岩.
