Abstract
Unusual corundum-fuchsite rocks with Al2O3 contents up to 89 per cent and Cr2O3 values up to 2.8 per cent were investigated from two localities in Zimbabwe and Transvaal. They form lenses within volcano-sedimentary series of different metamorphic grades and are closely associated with metamorphic ultramafics.
