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.
A dolerite is the medium-grained equivalent of a basalt-a basic rock dominated by plagioclase and pyroxene. Dolerite can contain clinopyroxene and/or orthopyroxene and plagioclase is more calcic than andesine (50% anorthite). Dolerites also often include olivine or quartz and can be alkali basalts, olivine tholeiites or quartz tholeiites. They can contain a wide range of accessory minerals including hornblende and biotite.
