【摘要】 本文对新疆可可托海3号伟晶岩脉中的绿柱石与阿祖拜328、528号伟晶岩脉中的宝石级绿柱石开展拉曼光谱对比研究,获得以下主要结论:①阿祖拜328、528号伟晶岩脉中宝石级绿柱石以富含Ⅰ型H₂O为特征,可可托海3号脉早期形成的结构带（Ⅰ-Ⅱ带）中绿柱石以及相对富H₂O岩浆体系中形成的绿柱石（Ⅳ带）以存在Ⅰ型H₂O为主,演化程度相对较高,岩浆体系中结晶的结构带（Ⅲ带）以及岩浆-热液过渡阶段体系形成的结构带（Ⅴ带）中绿柱石以含有Ⅱ型H₂O为特征;②在可可托海3号脉以及阿祖拜328号、528号脉绿柱石矿物中均发现冰晶石矿物包体,指示伟晶岩岩浆含有较高的F含量;③绿柱石通道水类型（Ⅰ型H₂O、Ⅱ型H₂O）及相对比例,是伟晶岩岩浆-热液演化过程及其形成条件的响应,在相对氧化的岩浆体系中主要形成绿柱石矿物,而相对还原的富H₂O岩浆体系更有利于海蓝宝石形成。更多还原

【Abstract】 The differences between green beryls from the Kokotokay No.3 pegmatite and aquamarines from the Azubai area in Xinjiang were investigated by means of laser Raman spectroscopy.Some conclusions have been reached:① Gem-grade beryls from Azubai No.328 and No.528 pegmatite veins are characterized by high content of Type I channel water,and beryls from Kokotokay No.3 pegmatite show interchanging properties.Beryls formed during early crystallization(zone I and zone Ⅱ) and in the magmatic system that is comparatively rich in water(zone Ⅳ) feature predominantly Type Ⅰ channel water,whereas beryls from the more evolved textural zones,i.e.,zones formed at magmatic and magmatic-hydrothermal stages(zone Ⅲ and zone Ⅴ,respectively) comprise mainly Type Ⅱ channel water.② The discovery of cryolite inclusions in Kokotokay No.3,Azubai No.328 and No.528 pegmatite veins indicate that the pegmatitic magmas have a relatively high content of F.③ The types of channel water in beryls(Type Ⅰ and Type Ⅱ water) and their relative proportions are subject to the magmatic-hydrothermal evolution of the pegmatites as well as the formation conditions.The pegmatitic magma system that is relatively oxidized forms primarily beryl minerals,while the system that is relatively reduced and rich in water is favorable for the formation of aquamarine.更多还原
