SAnTex is a Python library which calculates the full elastic tensor of rocks from modal mineral composition, crystallographic orientation, and a crystal stiffness tensor catalogue that accounts for the dependency of elasticity with pressure and temperature.

pide is a Python3 library for calculating geophysical parameters (e.g., electrical conductivity, seismic velocity), employing the results from experimental petrology, mineral/rock physics, and thermomechanical modelling studies. pide can calculate the theoretical electrical conductivity of any earth material that exists in the literature. pide can also calculate seismic velocity utilising the external 'sister' library `santex`. Using these theoretical calculations, users can utilise inversion modules to decode geophysical anomalies compositionally or convert thermomechanical models into geophysical observables. With a given spatial mapping of earth materials, which can preferentially be loaded from a thermomechanical model, pide can be used to build synthetic electrical conductivity and seismic velocity models and generate gravity and magnetic anomalies. Moreover, it is built as a modular tool, so users can easily build their functions.
