calcrete (Johns, 1976). Graphite ore zones are up to 12 m thick and are stratiform and stratabound, being high-grade metamorphic equivalents of carbonaceous sediments (Taylor and Berry, 1990). The host rocks are strongly weathered. Graphite has been recrystallised adjacent to pegmatites to form coarse flakes (Parker, 1993a).
