Magnetotellurics in the Eger Rift
An overview of subsurface imaging of different tectonic features
The Bohemian Massif represents the easternmost part of the geodynamically active European Cenozoic Rift System. This region hosts the contact between three tectonic units of the Variscan Belt, the NE-SW trending Eger Rift and the NNW-SSE striking Marianské Lázne fault. It is char

3D CSEM Forward Modelling
Testing Adaptive Mesh Refinement Approaches on an Ore Body Model
We develop a forward modelling code to simulate 3D land-based controlled-source electromagnetic (CSEM) problems in frequency domain with unstructured tetrahedral meshes. The algorithm accounts for isotropic electrical resistivity and magnetic permeability variations in the subsur
