Bushveld, Platreef

Northern limb of the Bushveld Complex, South Africa

Magmatic (Ni-Cu-PGE, carbonatites)PGE - Cu, Ni

Type
PGE and Cu-Ni sulfides

Mineralised horizon of the northern limb. Its chrome spinels are low in chromium and high in alumina (Cr# below 20, Al2O3 above 32%).

9 / 14.2 ‰sulfides (underlying Lower Zone peridotite)
Heavy values attributed to assimilation of sedimentary sulfur (sulfates) by the magmas, clearly heavier than in the Merensky and UG2.

0.7 / 18.6 ‰Footwall Cyclic Unit (Flatreef)
A very wide range, reflecting the heterogeneity of sedimentary contamination in the Flatreef and Platreef of the northern limb, unlike the homogeneity of the Merensky and UG2.
