摘　　要：The P₂O₅ contents of feldspars in the Yashan F-rich and P-rich granite yield a maximum value of 0.93% （in albite） and a maximum average value of 0.65% （hereinafter weight percent） （in K-feldspar）, and is generally between 0.10% and 0.35%. Most of the distribution coefficient D_p[Ab/Kf] values are greater than 1 （1.13—28.9）. The study shows that phosphorus could preferably enter the albite structure mainly by PAISi₂ substitution relative to K-feldspar.The P2O5 contents of feldspars in the Yashan F-rich and P-rich granite yield a maximum value of 0.93% (in albite) and a maximum average value of 0.65% (hereinafter weight percent) (in K-feldspar), and is generally between 0.10% and 0.35% .
