Petrolog4 v.4.1.1 is available on petrologsoftware.com

14 May 2024

Petrolog4 v.4.1.1 has been released and can be downloaded from the website.

New features:

Added the model of Ding et al. (2018) for sulphide-saturation of silicate melt (New high pressure experiments on sulphide saturation of high-FeO* basalts with variable TiO2 contents – Implications for the sulphur inventory of the lunar interior. Geochimica et Cosmochimica Acta, Volume 222, pages 319 –339).

Added the model of Wallace and Carmichael (1992) for sulphide-saturation of silicate melt (Sulfur in basaltic magmas. Geochimica et Cosmochimica Acta 56, 1863-1874).

Added an option to model crystallisation ignoring sulphide saturation by choosing ‘No S saturation’ option among models for sulphide saturation.

Added the model of Boulliung and Wood (2023) for sulphur oxidation state in silicate melt (Sulfur oxidation state and solubility in silicate melts. Contributions to Mineralogy and Petrology 178: 56).

Changed implementation of the Smythe et al. (2017) sulphide saturation model so that it is now not linked to the Kiseeva and Wood (2015) sulphide composition model, but can be used with any model of sulphide composition that involves Ni and Cu contents.

Added calculations of the saturation pressure by a H2O-CO2 fluid when using ‘Melt Liquidus Association’ calculations option with melt compositions that contain H2O and/or CO2. The saturation pressure is calculated for each available fluid saturation model.

This version also resolved several issues identified since the last release.

Petrolog4 v.4.1.0.2 is available on petrologsoftware.com

22 April 2024

Petrolog4 v.4.1.0.2 has been released and can be downloaded from the website.

This versions resolved several issues identified by our users, with the main one being a mistake in the implementation of Fortin et al. (2015) sulphur solubility model that led to progressively higher calculated S contents at elevated oxygen fugacity.
