雅山富氟高磷花岗岩长石中P_2O_5测定结果为最高值0.93%(Ab),最高平均值0.65%(Kf),一般为0.10%～0.35%;分配系数D_(p[Ab/Kf])值除个别外,均大于1(1.13～28.9),表明磷主要以PAlSi_(-2)替换方式相对于钾长石择优进入钠长石结构中.
The determination of P_2O_5 in the feldspars of Fluorophosic and P-rich granites has the highest value of 0.93% (Ab) and the highest average of 0.65% (Kf), generally 0.10% to 0.35%. The partition coefficient D_ (p [Ab / Kf]) (1.13 ~ 28.9) except for a few, indicating that phosphorus preferentially enters the albite structure relative to K-feldspar by PAlSi_ (- 2) substitution.
