Metamorphic Rock

no

Gneiss.

You WOULD expect to find metamorphic rocks in the recesses (deep layers) of the Earth's crust. But not in the mantle or core.

Metamorphic means changed - and rocks - either sedimentary or igneous - get changed by the heat and pressures found in the deep crust.

the deeper into earth crust the higher the pressure that forms metamorphic rocks

After metamorphism, granite can transform into a type of metamorphic rock known as gneiss. This process involves the alteration of the original granite's minerals and the development of foliation, which is characterized by the alignment of mineral grains under heat and pressure. Gneiss typically exhibits a banded or layered appearance due to the segregation of light and dark minerals.

Sandstone, limestone, and shale are non-examples of metamorphic rocks because they are sedimentary rocks formed from the accumulation and compaction of sediments, rather than being subjected to the high pressure and temperature conditions required for metamorphism. Additionally, granite, which is an igneous rock formed from the cooling and solidification of magma, is another non-example of a metamorphic rock.

Granite

yes

phyllite

The particle size of gneiss can vary, but it typically consists of medium to coarse-grained minerals that are visible to the naked eye. Gneiss is a metamorphic rock formed from the recrystallization of pre-existing rocks under high heat and pressure, resulting in a distinctive banded texture.

Minerals have certain properties, or characteristics, that help to identify them. Minerals can be identified by their color, luster, streak, cleavage, hardness, specific gravity, and even by their chemical composition.

Hydrothermal relates to the action of water under the conditions of high temperature, especially in the forming of rocks and minerals. This means the process of the change of the structure of the rock, caused by the heat - a metamorphic process

An index mineral is used in geology to determine the degree of metamorphism a rock has experienced.

A foliated metamorphic rock forms when crystals combine and form visible bands

The alignment of minerals to form a planer fabric. This may give the rock a banded appearance.

yes it is.

Yes, clean slate is an expression. The official definition for the word clean slate is "an opportunity to start over without prejudice."

Slate is natural.

Yes, a metamorphic rocks is an existing rock that has been transformed via heat and pressure.

Slate.

Slate

No

Slate is the low-pressure, low-temperature metamorphic rock whose parent rock (protolith) was shale. Clay minerals which were present in the shale have started to change into mica, a platy mineral, which give slate its cleavability. Because the transformation of the clay minerals is not complete, slate generally appears dull in light.

With exposure to higher temperatures and pressures, shale will become the metamorphic rock phyllite. In phyllite, the transformation of the clay minerals to nearly visible micas and other minerals is nearly complete, giving the rock a very shiny appearance. It may also appear wavy and foliated.

With higher temperature and pressure, phyllite will become the metamorphic rock schist.

well, when metamorphic rock is under billions of pounds of pressure, it tends to form life forms. such as lizards snd small reptiles. When trillions of pounds of pressure are on metamorphic rocks, they form small people that live in an underground village beneath indonesia.
