What is Petrolog?
Q. Are there limitation to the compositions of magma that can be modelled with Petrolog4?
A. Yes, the range of magma compositions and crystallisation conditions that can be modelled by Petrolog4 is limited by the availability of published phase – silicate melt equilibrium models. Petrolog4 (v.4.0.6) does not include any models for amphibole, mica, alkali feldspar, quartz and apatite. This does not allow for modelling of anhydrous diorite – rhyolite compositions and hydrous andesites – diorite – rhyolite compositions.
Q. Is Petrolog4 different from other modelling software?
A. Yes, Petrlog4 uses a different conceptual approach to crystallisation modelling and a different algorithm, and it also offers a range of additional tools that are not available in other modelling software. You can read more about Petrolog4's approach to modelling here.
Previous versions of Petrolog
Q. Will Petrolog3 continue to be available for free?
A. Yes, Petrolog3 can be downloaded for free from here
Petrolog on Mac
Q. Will Petrolog4 be available on macOS?
A. Mac users can run the current version of Petrolog4 on their computer after installing Windows under a virtual machine (e.g., www.parallels.com). Releasing a macOS version of Petrolog4 is planned for the future, however its release will be dependent on the number of licensed users.
Petrolog developers
Q. Are Leonid and Pavel still involved with Petrolog development and maintenance?
A. Yes, both Leonid and Pavel are continue to be the main developers of Petrolog.
Using Petrolog
Q. Are there recommended sets of calculation parameters for different magma types?
A. Yes, available files with recommended parameter settings are included with Petrolog when it is downloaded from this website. The files can also be downloaded here.
Q. Can I discuss the choice of calculation parameters for my projects with the developers?
A. Yes, Petrolog licence holders can email questions to support@petrologsoftware.com. We aim to respond as soon as possible within 5 business days.
