摘要
本文研究了新疆阿尔泰青河92号脉、可可托海3号脉和柯鲁木特112号脉伟晶岩中锂辉石所含的包裹体,其包裹体类型主要有两类:流体熔融包裹体和液体包裹体。根据显微测温和包裹体性质,求出了包裹体形成时的温度、压力等有关参数。借助激光拉曼探针测定,对流体熔融包裹体成分作了估算。流体熔融包裹体成分研究表明阿尔泰伟晶岩成因与岩浆-热液过渡阶段有密切联系。
This paper studies the inclusions in spodumenes from Qinghe No.92 Keketuohai No.3 and Kelumute No.112 vein pegmatites of Altai in Xinjiang Province.Two types of inclusions have been found:fluid-melt inclusions and liquid inclusions.Based on both microthermometry and property of inclusions,the temperature,pressure and related parameters for formation of inclusions have been evaluated.The compositions of fluid-melt inclusions have been estimated by the determination of Laser Raman microprobe.The research of compositions of fluid-melt inclusions indicates that the genesis of Altai pegmatite was close ties with magmatic-hydrothermal transitional stage.
