This paper introduces Petrolog3, software for modeling (1) fractional and equilibrium crystallization, (2) reverse fractional crystallization at variable pressure, melt oxidation state and melt H2O contents, and (3) postentrapment reequilibration of melt inclusions in olivine. Petrolog3 offers an algorithm that allows calculations with a potentially unlimited number of (1) mineral-melt equilibrium models for major and trace elements and (2) models describing melt physical parameters such as density and viscosity, melt oxidation state, and solubility of fluid components in silicate melts. The current version of the software incorporates 46 mineral-melt equilibrium models for 8 minerals; 3 models describing distribution of trace elements between minerals and melt; 4 models of melt oxidation state; 1 model for H2O solubility in silicate melts; and 4 models describing melt density and viscosity. The idea behind the program is to provide the community of igneous petrologists and geochemists with a user-friendly interface for using any combinations of available mineral-melt equilibrium models for computer simulation of the crystallization process.

The journal 'Geochemistry, Geophysics, Geosystems' publishes research papers on Earth and planetary processes, focusing on understanding the Earth as a system. We welcome observational, experimental, and theoretical studies of the solid Earth, hydrosphere, atmosphere, biosphere, and the solar system across all spatial and temporal scales. Articles should be of broad interest and encourage interdisciplinary approaches. This peer-reviewed journal covers areas of interest including, but not limited to: the physical and chemical properties of the Earth, including its structure, composition, physical properties, dynamics, and evolution; principles and applications of geochemical proxies; physical properties, composition, and temporal evolution of major Earth reservoirs and their coupling; dynamics of geochemical and biogeochemical cycles at all spatial and temporal scales; physical and cosmochemical constraints on composition; origins and evolution of the Earth and other terrestrial planets; chemistry and physics of solar system materials related to the formation, evolution, and current state of the Earth and planets; and other relevant fields of Earth science.
