GFZ German research centre for geo sciences

Namibia / MT

Geodynamic processes related to passive continental margins - from lithospheric thinning to rifting and continental breakup - are of large geoscientific interest. In the past different working groups of GFZ and partners conducted experiments in Namibia and have shown that passive continental margins of the South Atlantic were effected by the still active Tristan de Cunha mantle plume and that the continental lithosphere along the current day margins experienced a series of orogenies before. In 1998 GFZ conducted a regional magnetotelluric profile with 33 stites on a profile between the Brandberg and the Erongo intrusive complex. This profile was extended to the south in 1999 and condensed across the Waterberg Fault/Omaruru Lineament.

Focus of the MT experiments is to gain an electrical conductivity image of the central part of the Damara Belt with its tectonic boundaries and structures.
