Abstract:

江西雅山黄玉锂云母花岗岩属典型的华南[富氟高磷花岗岩(P2O5=0.15%-0.55%),表现为富氟(F=1.07%-2.04%),强过铝性(A/NKC=1.26-1.60),具有很高的Li,Rb,Cs,Be,Nb,Ta含量和很低的Y、REE含量.磷锂铝石是雅山黄玉锂云母花岗岩中的主要磷酸盐矿物,其产出与否同体的Li,Rb,Cs含量密切相关;磷锂铝石和长石矿物都是雅山黄玉锂云母花岗岩中磷的主要贮体,并且相互之间呈互补关系,当出现磷锂铝石时,磷锂铝石为全岩磷的主要贡献者,当无磷锂铝石晶出时,长石矿物为全岩磷的主要贡献者,体系的强过铝性以及很低的REE,Y,Ca含量使得磷灰石,独居石,磷钇矿都难以达到饱和结晶,磷灰石为少量出现,并且大部分为晚期形成;独居石和磷钇矿都为极少出现,反映出雅山岩体演化过程中具有独居石,磷钇矿等稀土磷酸盐矿物的结晶分离,铍磷酸盐矿物-羟磷铍钙石的出现反映了雅山黄玉锂云母花岗岩存在岩浆期后的含Be,Ca热液流体的作用。
