- Abstract
We describe an impressive ~55 m high outcrop from the Pilanesberg Platinum Mine open pit, located in the North-Western Bushveld Complex. The outcrop exposes the complete two-dimensional structure of three Merensky Unit potholes that cut several metres down into the underlying footwall anorthosites. The transgressive field relationships are interpreted to have resulted from thermochemical erosion of the footwall rocks by new pulses of magma replenishing the chamber and resulting in incremental growth of the Bushveld Complex.
