雅山富氟高磷花岗岩具较高的全岩磷含量(0.15%~0.55%),长石是磷的主要赋存矿物,磷以PAlSi-2替换方式进入长石结构中。各种结晶习性的长石的磷含量各不相同。早世代钠长石和雪球结构中钠长石包裹体的结晶较早,平均磷含量分别为0.18%和0.19%,而晚世代钠长石和环带钾长石中钠长石嵌晶的结晶稍晚,具较高的平均磷含量(分别为0.25%和0.23%)。钾长石的磷含量相对于钠长石总体上较低,早期结晶的雪球结构主晶钾长石和环带钾长石的磷含量最低,分别为0.04%和0.02%,晚期细粒钾长石的平均磷含量略高(0.19%)。长石对全岩磷的贡献率还与磷锂铝石等磷酸盐副矿物是否达到饱和有关,当无磷锂铝石结晶时,长石磷的贡献率约为76%,反之则约为31%。
Yashan Fluorine-rich high-phosphorus granite has a higher total rock phosphorus content (0.15% ~ 0.55%), feldspar is the main phosphorus mineral, phosphorus to PAlSi-2 replacement into the feldspar structure. The feldspar phosphorus content of various crystallization habits varies. Early albite and snowball structures crystallized earlier in the albite inclusions, with average phosphorus contents of 0.18% and 0.19%, respectively, whereas the later-generation albite and albite in the kerogen Crystals crystallized later with higher average phosphorus content (0.25% and 0.23%, respectively). The phosphorus content of K-feldspar is generally lower than that of albite, and the content of phosphorus in the early-crystallized snowballs is 0.04% and 0.02%, respectively. The late-stage The average phosphorus content of fine-grained potash feldspar is slightly higher (0.19%). The contribution of feldspar to total rock phosphorus is also related to whether the phosphate siderite, such as lithium-aluminosilicate, is saturated. When phosphorus-free lithium-aluminum-stone is crystallized, the contribution of feldspar is about 76%, and vice versa %.
