Galvanic distortion of magnetotelluric (MT) data due to small-scale surficial bodies or due to topography is one of the major factors that prevents accurate imaging of the subsurface. We present a 3-D algorithm for joint inversion of MT impedance ten

As an additional opportunistic component to the southern African magnetotelluric experiment, natural-source audio-magnetotelluric (AMT) data were acquired during phase IV to investigate the local-scale electric conductivity subsurface structure in th

[1] Archean cratons, and the stitching Proterozoic orogenic belts on their flanks, form an integral part of the Southern Africa tectonic landscape. Of these, virtually nothing is known of the position and thickness of the southern boundary of the com

a b s t r a c t Despite many years of work, a convincing evolutionary model for the Limpopo belt and its geometri- cal relation to the surrounding cratons is still elusive. This is partly due to the complex nature of the crust and upper mantle struct

A finite-element method for computing the electric field in a 3-D conductivity model of the Earth for plane wave sources, thus enabling magnetotelluric responses to be calculated, is presented. The method incorporates in the iterative solution of the

SUMMARY 2-D isotropic approaches are standard for magnetotelluric (MT) data modelling and inversion. Unfortunately, the real subsurface structure is not isotropic everywhere and one should be aware of the possible consequences of applying an isotropi

The limestone of the western flank of the Innerste Mulde in Lower Saxony, Germany, host a 27 km long karst water system which is surface-mapped by sinkhole and collapse structures. The karst water emerges at springs – one of them is a spring called
