WebGraphite most often occurs in metamorphic rocks formed from regional metamorphism or contact metamorphism of organic-rich sedimentary rocks, such as organic-rich marble, quartzite, schist, gneiss, and metamorphosed coal. The sediment’s original organic component provides the source for the carbon from which graphite forms.
