Geophysical constraints on the shape and emplacement of the Bushveld Complex

Despite the size of the Bushveld Complex and the wealth of its mineral deposits, it is perhaps surprising that its three dimensional structure, tectonic environment and emplacement mechanism are so poorly characterised and understood. Here we review the geophysical data that constrain the three dimensional shape of the Bushveld complex, the tectonic environments that have been proposed for the emplacement of the Bushveld Complex and a variety of proposed emplacement mechanisms.
