    The platy minerals can be graphite, talc, or hornblende from carbonaceous, basaltic, or other sources. The individual mineral grains in schist, drawn out into flaky scales by heat and pressure, can be seen with the naked eye. Schist is characteristically foliated, meaning that the individual mineral grains split off easily into flakes or slabs.
