The Zwartkop and Groot-Marico chromite deposits are located on the Western and Far Western (Groot-Marico) Lobes of the 2050 Ma Bushveld layered mafic complex in South Africa respectively.   These sections contains large resources and mines exploiting extensive reserves of Chromite.   Zwartkop is adjacent to the Amandelbult Platinum mine.

These mines exploit chromitite layers within the Lower Critical Zone of the Bushveld Complex.   See the Elandsdrift record for information on other chromite reefs worked in the complex.

For details of the Bushveld mineralisation, stratigraphy and chromite bearing reefs, see the Bushveld Complex record.
