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. It is a finite-element forward modeling approach code based on the architecture of the CAGES code (Zeyen & Fernàndez 1994). For a detailed description of LitMod2D the reader is referred to Afonso et al. (2008,https://doi.org/10.1029/2007GC001834 and Kumar et al. (2020,https://doi.org/10.1029/2019GC008777).
