Examples of common metamorphic rocks quartzite is a coarse grained metamorphic rock derived from sandstone. Marble is typically not foliated although there are exceptions. Pebble conglomerates from near kaladar and nepheline syenite. Marble is a metamorphic stone formed by subjecting limestone to heat or pressure.

It is composed primarily of the mineral calcite caco 3 and usually contains other minerals such as clay minerals micas quartz pyrite iron oxides and graphite. Impurities produce pale gray brown or variegated colored rock. Although metamorphic rocks typically form deep in the planet s crust they are often exposed on the surface of the earth.
