Abstract:
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 DpAb/Kt] 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.
