Future plans | Petrolog

Planned in version 4.2.1

Users who hold an active licence can:

suggest new models and functionality to be added to Petrolog, and
vote for the priority of new features to be added in future releases of Petrolog

List of possible new features

Plagioclase-melt equilibrium model of Waters and Lange, 2015 (An updated calibration of the plagioclase-liquid hygrometer-thermometer applicable to basalts through rhyolites. American Mineralogist, Volume 100, pages 2172–2184).

Zircon saturation model of Borisov et al., 2025 (Zircon solubility in silicate melts: New empirical models and thermodynamics. Chemical Geology, Volume 679, 122682).

CO2 and H2O melt saturation models of Shishkina et al., 2014 (Compositional and pressure effects on the solubility of H2O and CO2 in maﬁc melts. Chemical Geology, Volume 388, pages 112–129).

If you hold an active licence, you can leave your suggestion(s) using this form:

(I)* Normative mineralogy calculations.

List of possible new features (order is not significant; stars next to the item number indicate the complexity involved with adding the item; 3 stars indicate the most complex items)

(II)* Sulphur saturation during re-equilibration of melt inclusions in olivine.

(III)*** Modelling fluid-melt equilibrium in melt inclusions re-equilibrating with the host.

If you hold an active licence, you can vote for new features to be added in future releases of Petrolog using this form:

(V)** Modelling U-Th-Pb equilibrium during decay in closed and open systems.

(VI)*** Modelling laser-ablation ICP-MS signal on quadrupole instrument during ablation of micro-inclusions.

(VII)** Plagioclase composition on the liquidus of silicate melts at 1 atm model of Namur et al. 2012 (Prediction of plagioclase-melt equilibria in anhydrous silicate melts at 1-atm. Contrib Mineral Petrol, Volume 163, pages 133–150).

(VIII)*** Amphibole - silicate melt equilibrium model of Putirka 2016 (Amphibole thermometers and barometers for igneous systems and some implications for eruption mechanisms of felsic magmas at arc volcanoes. American Mineralogist, Volume 101, pages 841–858).

(IX)* Compositional profiles across zoned crystals formed as a result of fractional crystallisation.

(X)*** Modelling replenishment of the evolving magmatic system by a primitive melt for the case of equilibrium crystallisation.
