Common porphyroblasts include garnets and micas. Foliated texture: Platy minerals have a preferred orientation usually perpendicular to the direction of applied stress. Rocks tend to break along foliations.

Other platy minerals found in schists include chlorite, talc, and graphite. Chlorite schist is typically formed by metamorphism of ultramafic igneous rocks, as is talc schist. Talc schist also forms from metamorphosis of talc-bearing carbonate rocks formed by hydrothermal alteration. See more Schist is a medium-grained metamorphic rock showing pronounced schistosity.
