【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。更多还原

【Abstract】 The research on the mineralogical characteristics of A-type granitoids in southwest Tianshan,Baicheng 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.更多还原
