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 metamorphic rock that does not have its minerals arranged in bands is called nonfoliated. Nonfoliated metamorphic rocks do not break in layers. Marble is formed from limestone and shows large calcite crystals. Quartzite is formed from sandstone and shows large quartz crystals.
