BurnMan is an open source mineral physics toolbox written in Python to determine seismic velocities for the lower mantle. 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 to the lower mantle included or easily define one of their own.
