Summary:Comparisons were made between the various ore sulphides are phyllosilicates (illite and chlorite) in five different orebodies in metapelitic rocks in this part of the pyrite belt. The textures indicated low-grade metamorphism conditions below the brittle-ductile boundary for pyrite. Illite and chlorite crystallinity data point to a sub-greenschist anchizonal metamorphism with a peak at 350°C and 3.5 ± 2 kbar. [R.A.H.]
