Africa is a rich source of minerals. The main mining fields in Africa are located on the ring structures and linears from the surface right to the limits of detailed data at 400 km depth. The mechanism and source of the fluid for most mineralisation may have been discovered by this research.

This Part 6 section describes the relationship of the metal and diamond mineralisation to the linear and ring structures observed in African seismic tomography at 170-250 km depth. Africa is a rich source of minerals. The main mining fields in Africa are located on the ring structures and linears from the surface right to the limits of detailed data at 400 km depth.
