Two-dimensional, 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 isotropic inversion to anisotropic data. The work presented was motivated by finding an unusual conductor that seemed to be downwarped into the lithospheric mantle compared to the neighbouring terranes where it appeared in the mid- to lower-crust. One major difference between the terranes is the presence of the Okavango giant mafic dyke swarm (NE Botswana), where the conductor is imaged to be in the lithospheric mantle. The very limited width of the dykes makes them more an anisotropic feature than ...
