| Abstract: | With the purpose to improve the garnet-biotite geothermometer, the published data on the interaction parameters have been
compared for the components of garnet and biotite solid solutions. On the basis of the reference metapelitic series, it has
been shown that the temperatures determined using various calibration equations for garnets enriched in Ca and Mn are systematically
over- or underestimated. The difference between the estimated and expected temperatures may be as great as many tens of degrees. |
