Abstract

We have identified and corrected an algebraic error originally made in the formulation of the thermodynamic model for silicate melt in Holland, Green and Powell (2018), J. Petrol., 59, 881-900, article egy048. The error was propagated subsequently in Tomlinson and Holland (2021), J. Petrol., 62, 1-23, article egab012. Below we explain the algebraic correction, and describe the scale of its impact on typical calculations, which in many systems is likely to be within model uncertainty at worst, and negligible at best. We provide a correctly formulated re-calibration of the (Holland et al., 2018) silicate melt model. In presenting illustrative calculations with this melt model, we take the opportunity to summarise the changes to the accompanying thermodynamic models for minerals that we have implemented over several publications since 2018.
