Foliated Metamorphic Rocks | Mineralogy4Kids

Foliated metamorphic rocks are formed within the Earth''s interior under extremely high pressures that are unequal, occurring when the pressure is greater in one direction than in the others (directed pressure). This causes the minerals in the original rock to reorient themselves with the long and flat minerals aligning perpendicular to the greatest pressure direction.
