Abstract

This fractionation can be described by the equation 1000 ln alphaF (sub phl-Cc) = 0.43-(1.84 times 10 (super 6) )/T (super 2) over the range 400-800 degrees C, 11 kbar. When this equation is combined with the published results for quartz-calcite, it yields calculated T that are, on average, 30% lower than those obtained from an empirical quartz-biotite calibration previously used. Correlations between delta (super 18) O fractionation and mean O (sub 2) electrostatic site potentials demonstrate that both the magnitude and T dependence of the fractionation measured in this study are consistent with data for six other minerals calibrated using the same experimental technique.
