摘  要:The P<sub>2</sub>O<sub>5</sub> 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<sub>p[Ab/Kf]</sub> values are greater than 1 (1.13—28.9). The study shows that phosphorus could preferably enter the albite structure mainly by PAISi<sub>2</sub> 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% . Most of the distribution coefficient DP[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.
