Both foliated and nonfoliated rocks begin their lives as either sedimentary, igneous or another metamorphic rock. Due to geological changes, a metamorphic rock of the foliated or nonfoliated type will be created. These geological changes can be due to heat and temperature from the recrystallizing rock being found deep within the earth's crust.
A foliated metamorphic rock will have banded minerals. The mineral flakes will appear to be parallel to the rock and will look layered. When a foliated rock breaks, a thin rock fragment will result.
