The difference between regular shungite and elite or noble shungite is in the proportion of organic carbon in it. Regular shungite contains from 35 to 60 per cent of organic carbon while the percentage of carbon in elite shungite is much higher and totals from 92 to 98 per cent.
exists and is an alternate of . The difference lies in the degree of metamorphism. Metamorphism is the solid state recrystallisation of minerals. Both rocks are metamorphosed by regional metamorphism (directed pressure), however schist is metamorphosed more than slate. Therefore Slate is only a low grade metamorphic rock whereas schist is a medium grade metamorphic rock (gneiss is high grade).
