Local gravity field modelling with Python

LitMod2D_2.0 is a tool to unravel the thermal, compositional, density, and seismological structure of the crust and upper mantle (~400 km depth) along cross-sections by integrating geophysical and geochemical dataset in a self-consistence thermodynamic manner.
