Description	Recent crystallographic data indicate that in biotite Ti and Fe3+ order preferentially onto the M2 octahedral site rather than onto the M1 site as assumed in previous solution models for K2O–FeO–MgO–Al2O3–SiO2–H2O–TiO2–O2 (KFMASHTO) biotite. In view of these data, we reformulate and reparameterize the former biotite solution model. Our reparameterization takes into account Fe-Mg order-disorder and ferric iron contents of natural biotites as well as both natural and experimental observations on biotite Ti-content over a wide range of physicochemical conditions. In comparison to previous biotite models, the new model reproduces the Ti-content and stability field of biotite as constrained by experiments with significantly better accuracy. The predictive power of the model is tested by comparison with petrologically well-characterized natural samples of SiO2-saturated and SiO2-undersaturated rocks that were not used in the parameterization. In all of these tests, the reformulated model performs well.
