MTGeophysics.jl

A software repository for magnetotelluric geophysics research and applications.

Forward modelling

Exact 1D layered-earth responses and a 2D TE/TM finite-difference solver with topography and lakes. 3D runs through ModEM.

Deterministic inversion

Gauss–Newton and NLCG in 1D and 2D, set up from a handful of small text files.

VFSA inversion

Very fast simulated annealing in 1D, 2D and 3D. Several chains give an ensemble of models and an estimate of uncertainty.

Data and meshes

Read and rotate ModEM data files, and build 2D and 3D meshes with topography and water from a data file.

Interactive 3D viewers

Depth slices, cross-sections, phase tensor maps and model editors, with shapefile overlays and GIS export.

What is MTGeophysics.jl?

MTGeophysics.jl is part of the JuliaGeophysics ecosystem and is intended for both research and real-world applications. It provides reusable forward-modelling, inversion, and visualization components so you can prototype new machine-learning methods, inversion strategies, and data-analysis ideas quickly without rebuilding core magnetotelluric tooling from scratch. More broadly, JuliaGeophysics aims to build a tightly integrated yet modular ecosystem for multiphysics workflows, multisource data integration, and uncertainty quantification.
