Photographs and brief descriptions of some common types of metamorphic rocks are shown on this page. Gneiss is a foliated metamorphic rock that has a banded appearance and is made up of granular mineral grains. 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. The links below are an attempt to show the common types of folicated and non-foliated metamorphic rocks and some of the varieties that are found. It is by no means a complete list of the types and varieties that are found in the world.

These are invariably green, black and, more rarely, blue in color. This general name encompasses rocks that are also referred to as greenschist , Foliated metamorphic rocks such as gneiss, phyllite, schist, and slate have a layered or banded appearance that is produced by exposure to heat and directed pressure. Non-foliated metamorphic rocks such as hornfels, marble, quartzite, and novaculite do not have a layered or banded appearance. 1.2K views Sponsored by Best Gadget Advice Slate is a fine-grained, homogeneous metamorphic rock, which is foliated (in geology: consisting of layers, layered).

These rocks are most often deduced from single mineral sedimentary rocks. High temperature and pressure erases out the fossils of the metamorphic rocks. Extreme pressure may also lead to foliation, the flat layers that form in rocks as the rocks are squeezed by pressure (figure 2). Foliation normally forms when pressure is exerted in only one direction.
