A thermodynamic and geophysics toolkit for the Earth and planetary sciences
BurnMan is an open source mineral physics toolbox written in Python to
generate physical properties for the Earth and other planets. At its simplest, BurnMan calculates
the isotropic thermoelastic moduli by solving the equations-of-state for a
mixture of minerals defined by the user. The user may select from a list of
minerals applicable included or easily
define one of their own.
- extensive mineral database (Holland and Powell, 2011; Stixrude and Lithgow-Bertelloni, 2005; 2011 ).
- form composites of arbitrary combination of minerals
- popular solid solution models(ideal, symmetric, asymmetric, subregular), with class constructors designed to make solid solutions easy to read and create
- easy plotting and comparison of seismic profiles from 1D (and soon) 3D seismic models
- many examples highlighting different features of BurnMan
- different thermoelastic models including Vinet, Birch Murnaghan, Mie-Debye-Grüneisen, Modified Tait)
- tools to fit parameters for equations of state with experimental data not only in P-V-T, but in any thermodynamic property, such as seismic velocities and enthalpies
- tools to calculate chemical activities, potentials and fugacities of mineral assemblages
- different averaging schemes (Reuss, Voigt, VRH, Hashin-Shtrikman)
- different geotherms
- a “Planet” class, which self-consistently calculates gravity profiles, mass, moment of inertia of planets given the chemical and temperature structure of a planet
- potential to propagate uncertainty, both when fitting parameters and when forward modeling
- creates output to be input in software for synthetic seismograms: Mineos (Masters et al. 2014) and AxiSEM (Nissen-Meyer et al. 2014)
- generates smoothed property grids to create 1D adiabatic profiles which can be used by the geodynamics code ASPECT
- extensible: all parts can be replaced by user-written modules if desired
- repository of work published using BurnMan (accepting script submissions from the community)
