雅山黄玉锂云母花岗岩是雅山复式岩体的最晚阶段岩体 ,具较高的磷含量 (WP2 O5 =0 .1 5%～ 0 .55% ) ,长石矿物是磷的主要赋存矿物 ,磷以PAlSi-2 替换方式进入长石结构中 ;锆石是雅山花岗岩重要的稀有元素副矿物之一 ,它除了高度富铪、铀外 ,与一般锆石相比 ,还表现出显著富磷的特征 ,P2 O5含量变化主要为WP2 O5 =0 .2 3 %～ 4 .96%。磷主要以 (Y ,HREE ,Fe) 3 + P5+ (Zr,Hf) 4+ -1Si4 + -1、Al3 + P5+ Si4 + -2 、P5+ Al3 + Si4 + -1Zr4 + -1等替换方式进入锆石晶格中。富磷锆石是岩浆高度演化的结果 ,可以看成是高磷花岗岩的一种特征矿物。
YaShan topaz micaceous granite is the latest stage rock mass of the YaShan complex rock mass, with a high content of phosphorus (WP2 O5 = 0.1 5% -0.55%). The feldspar mineral is the main source of phosphorus The mineral and phosphorus enter the feldspar structure with the substitution of PAlSi-2. Zircon is one of the important rare elements of the Yaoshan granite. Compared with the normal zircon, the zircon also shows significant Phosphorus rich features, P2 O5 content changes mainly WP2 O5 = 0.23% ~ 4.96%. Phosphorus mainly enters the zircon (Y, HREE, Fe) 3 + P5 + (Zr, Hf) 4 + -1Si4 + -1, Al3 + P5 + Si4 + -2, P5 + Al3 + Si4 + -1Zr4 + Lattice. Phosphorite-rich zircons are the result of a high degree of magmatic evolution and can be considered as a characteristic mineral of high-phosphorus granites.
