The cation exchange reaction Fe3A12Si30 a 2 + KMg3A1Si3Olo(OH)2 = Mg3AlzSi30 m + KFe3-A1Si3Olo(OH)/ has been investigated by determining the partitioning of Fe and Mg between synthetic garnet, (Fe, Mg)3A11Si3012, and synthetic biotite, K(Fe, Mg)3A1Si3Olo(OH) 2. Experimental results at 2.07 kbar and

The partition of iron and magnesium between cordierite and garnet depends on P]~o as well as temperature. The apparently conflicting experimental data on the values of K D may be reconciled by considering the P]~O pertaining during the different experiments.

Experimental data combined with data from natural rocks have been used to calibrate a geothermometer based on the distribution of Fe 2 + and Mg between coexisting garnets and phengites. The pressure effect on the KD-value appears to be considerable. The calculated thermometer is expressed as T(K)=
