摘　　要：利用电子探针背散射(BSE)及阴极发光(CL)对波孜果尔A型花岗岩的矿物学特征进行了研究。结果表明,波孜果尔A型花岗岩主要造岩矿物包括石英、钠长石、钾长石、霓石、钠铁闪石和铁叶云母。副矿物包括锆石、烧绿石、钍石、萤石、独居石、氟碳铈镧矿和磷钇矿等。锆石CL图像表明,锆石具有黑核白边结构。The research on the mineralogical characteristics of A-type granitoids in southwest Tianshan, Baieheng County,Xinjiang was made by means of the backscattered electron images of electron probe microanalyzer, cathodoluminescence emission analysis, The results indicate that the major rock-forming minerals of A-type Granitoids are quartz, albite, K-feldspar, aegirine, arfvedsonite, and siderophyllite. The accessory minerals are mainly zircon, pyrochlore, thorite, fluorite, monazite, bastnaesite, xenotime and so on. CL images show that zircon has the typical structure of dark core and light rim.
