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. Two examples of metamorphic rock descriptions are medium-grained, hornblende-biotite schist, or fine- to medium-grained, garnetiferous, muscovite-chlorite-feldspar-quartz gneiss. A rock’s response to stress depends on the rock type, the surrounding temperature, and pressure conditions the rock is under, the length of time the rock is under stress, and the type of stress.

Metamorphic rock classifications include specific rock types based upon crystal size, diagnostic accessory minerals, mineralogical composition in increasing amounts greater than 15 percent, and structure. The word igneous means that the rock became a solid after having originally been hot magma, or lava. three examples of igneous rocks ,sedimentary rocks and metamorphic rock - 18236863 Feldspar and quartz are the most common minerals found in rocks. Examples of non-foliated metamorphic rocks are marble, quartzite and hornfels. Answer. Foliated rocks are banded metamorphic rocks that form when minerals realign as the result of pressure from opposing sides. The limestone might change in mineral assemblage or texture to form marble. The original rock is subjected to heat (temperatures greater than 150 to 200 °C) and pressure (100 megapascals (1,000 bar) or more), causing profound physical or chemical change.The protolith may be a sedimentary, igneous, or existing metamorphic rock. Rocks are generally separated into one of three different categories: igneous, sedimentary, and metamorphic. Foliated rocks are most often formed from mudstones and contain "fine-grained" or "platy" minerals that are usually too small to see with the naked eye; although some can be seen without aid.
