There are two basic types of metamorphic rocks. Foliated metamorphic rocks have a layered or banded appearance that is produced by exposure to heat and directed pressure. Examples of foliated rocks include: gneiss, phyllite, schist, and slate. Non-foliated metamorphic rocks do not have a layered or banded appearance.Many amphibolites are non-foliated and have this homogeneous and massive appearance. Figure 10.39, however, is a hand specimen of a garnet amphibolite, reminding us that amphibolites need not be nondescript and that they may be foliated. Amphibolites form by metamorphism and recrystallization of basalt or other mafic igneous rocks.

Gneiss, a foliated metamorphic rock. Quartzite, a non-foliated metamorphic rock.. Foliation in geology refers to repetitive layering in metamorphic rocks. Each layer can be as thin as a sheet of paper, or over a meter in thickness. The word comes from the Latin folium, meaning "leaf", and refers to the sheet-like planar structure. It is caused by shearing forces (pressures pushing …

The list below divides metamorphic rocks into foliated and nonfoliated varieties. Foliated rocks have platy or elongate minerals aligned in roughly parallel planes or in wavy bands or planes. Nonfoliated rocks may show colored bands that reflect minute impurities in the rock, but the dominant minerals show no visible alignment.Foliated rocks are formed under a great amount of relatively equal pressure, where as non-foliated rocks are formed under high temperatures. Non-foliated rocks, however, lack this visual characteristic. See the image below. The reason for this is actually pretty intuitive.

The serpentinite is formed by the hydrous alteration and low-temperature metamorphic alteration of igneous ultramafic rocks.

Most commonly, non-foliated metamorphic rocks are formed around igneous intrusions. Here immense heat from magma or molten lava creates an environment for the process of metamorphism. The temperatures are exceptionally high, but the pressure is lower and equal in all directions. Thus, the minerals are not elongated like they are in foliated ...Is coal foliated or nonfoliated?
