Geology of the PGE Deposits in the Bushveld Complex, South Africa
The 0.5-1 m thick reef occurs 15-400 m below the Merensky Reef, with vertical separation between the two reefs increasing from west to east. The UG2 comprises two to four minor chromitite reefs with a chromite content of approximately 43.5% (Fig. 7). The PGE minerals occur as metal sulphides interstitial to the chromite grains.
