Olivine-liquid equilibria: Temperature, pressure and composition dependence of the crystal/liquid cation partition coefficients for temperatures at Hawaii, Iceland, and the mid-ocean ridge system, as inferred from olivine phenocrysts: evidence for thermally driven mantle plumes, Geochem. Geophys. Geosyst., 6, Q05L08, doi:10.1029/2005GC000915.] was found to systematically Chemical Geology 241 (2007) 207–233 www.elsevier.com/locate/chemgeoMg, Fe2+, Ca and Mn. J. Petrol., 24, 256–265.] geothermometer describes olivine liquidus temperature as a function of melt composition and pressure, and the composition of the liquidus olivine as a function of melt composition, pressure and temperature. The Herzberg and O'Hara [Herzberg, C., O'Hara, M.J., 2002. Plume-associated ultramafic magmas of Phanerozoic Age. Journal of Petrology, 43, 1857–1883.] geothermometer describes olivine liquidus temperature similarly to Ford et al. [Ford, C. E., Russell, D. G., Craven, J.A., Fisk, M. R., 1983. Olivine-liquid equilibria: Temperature, pressure and composition dependence of the crystal/ liquid cation partition coefficients for Mg, Fe2+, Ca and Mn. J. Petrol., 24, 256–265.], and olivine composition as function of melt composition only. The Putirka [Putirka, K.D., 2005. Mantle potential temperatures at Hawaii, Iceland, and the mid-ocean ridge system, as inferred from olivine phenocrysts: evidence for thermally driven mantle plumes, Geochem. Geophys. Geosyst., 6, Q05L08, doi:10.1029/2005GC000915.] geothermometer describes both olivine liquidus temperature and composition as function of melt composition only. A comparison of these three geothermometers with experimental data at 0.1 MPa and 1.5 GPa reveals
