摘要
新疆阿尔泰地区某些花岗伟晶岩含有金绿宝石，它是一种罕见的稀有元素矿物，而且具有极高的经济价值．通过对金绿宝石系统地进行X光衍射、化学成分、穆斯鲍尔和等离子光谱等方法测试及流体包裹体的研究表明：该矿物出现在高铝的变质岩地区，与钠长石、绿柱石紧密关生．并为进一步扩大寻找具有实用价值的矿物提供有益佐证．
Chrysoberyl in some granite pegmatite is a rare mineral that seldom seen in Altatic area ,and it is a valuable precious stone. In this paper, the authors made a detailed study on chrysoberyl by means of X -ray diffraction,chemical composition,Mossbauer spectrum and infrared spectroscopic analysis as well as measuring fluid inclusion. It is found that chrysoberyls are closed paragenetic relationship to albitites and beryls,and it usually occur in the strict of high aluminume metamorphic rock- It is annefficacious index mineral to look for more valuable precious stone.
