WebIf a greater intensity of pressure and temperature are applied, the slate is altered and becomes the rock phyllite—similar to slate, but somewhat coarsergrained; additional pressure and temperature yields a schist. An even greater increase in pressure and temperature transforms the schist into gneiss—a high-grade metamorphic rock.
