Geotherms

Unlike the pressure, the temperature of the lower mantle is relatively unconstrained. BurnMan provides lightweight burnman.classes.geotherm.Geotherm and burnman.classes.geotherm.GeothermFromPressures classes that store a geotherm defined by arrays of depths and temperatures or pressures and temperatures respectively. Both classes have a temperatures() method that takes an array or list of depths as input and outputs the corresponding temperatures along the geotherm. In addition, the burnman.classes.geotherm.GeothermFromPressures class has a temperatures_from_pressures() method that takes an array or list of pressures as input. A number of geotherms from the literature are provided. See Geotherms for a list.

Also implemented in BurnMan is an burnman.classes.geotherm.AdiabaticGeotherm which allows for the computation of adiabatic temperature profiles given a pressure to depth conversion, a material, and an anchor temperature and pressure. Again, see Geotherms for more details.
