Metamorphic rock can also be formed from tectonic processes such as continental collisions.
Gneissic areas represent the root zones of ancient mountain belts. Chemical composition Metamorphic rocks may have the same chemical composition as other rocks, and this provides evidence for how they were formed. Here is a picture of quartzite. Example of foliated metamorphic rocks 2 See answers 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.

Foliated Metamorphic Rocks . Any type of rock—igneous, sedimentary, or metamorphic—can become a metamorphic rock. Metamorphic rocks do not melt, but the chemicals they contain may change their forms or crystal shapes. They are not made from molten rock – rocks that do melt form igneous rocks … Metamorphic rocks started out as some other type of rock, but have been substantially changed from their original igneous, sedimentary, or earlier metamorphic form. Alternative examples embody rock, hornfels, and novaculite. Igneous Rocks Examples. Metamorphic rocks are rocks that have changed or "morphed" into other kinds of rock. Different types of rocks become different types of metamorphic rock when exposed to heat and pressure. Slate is a metamorphic mudstone or shale. It is very hard and is number 7 on the Moh's Hardness Scale. Extreme heat or pressure. This is what often happens for rocks that don't have a special name for the metamorphic equivalent.

Anthracite is a type of coal with a high carbon count, few impurities and with a high luster (meaning it looks shiny). Example: limestone and slate create shale. As metamorphic grade increases, what do we generally observe in terms of the degree of foliation in rocks? Igneous Rocks.

Low-grade metamorphic rocks are often fine grained. Examples of metamorphic rocks are schist (a converted basalt), quartzite (a compressed sandstone), and marble (a compressed limestone or dolomite). Metamorphic rocks usually do not undergo further change when they are brought back to the surface. Interestingly, since the Taj Mahal is made up entirely of marble, the monument is one big metamorphic rock. The three major classes of metamorphic rock are based upon the formation mechanism.

The very hot magma, as it moves into a rock close to the surface, the temperature of the rock increases sufficiently to bring about changes in the mineral composition as well as texture of the surrounding rocks.
