What does metamorphic rock usually look like?

What does metamorphic rock usually look like?

Metamorphic rocks were once igneous or sedimentary rocks, but have been changed (metamorphosed) as a result of intense heat and/or pressure within the Earth’s crust. They are crystalline and often have a “squashed” (foliated or banded) texture.

Do metamorphic rocks have different textures?

TEXTURES Textures of metamorphic rocks fall into two broad groups, FOLIATED and NON-FOLIATED.

Are metamorphic rocks all the same color?

Metamorphic rocks can be a sort of different colors. Because metamorphic rocks are formed from sedimentary, igneous, or other metamorphic rocks that…

Do all rocks look the same?

Different rocks have different characteristics because of their minerals, the ways in which the rocks were formed, and the processes that acted on the rocks since they were formed. They will then use their observations of the rocks to identify a particular rock from a collection.

How can you identify a metamorphic rock?

Metamorphic rocks are rocks that have become changed by intense heat or pressure while forming. One way to tell if a rock sample is metamorphic is to see if the crystals within it are arranged in bands. Examples of metamorphic rocks are marble, schist, gneiss, and slate.

Which characteristics are used to identify types of metamorphic rocks?

As with igneous and sedimentary rocks, metamorphic rocks are classified on the basis of texture (grain size, shape, orientation) and mineral composition.

Does not have a banded texture?

Nonfoliated metamorphic rocks do not have a banded texture. Contrast foliated and non foliated metamorphic rocks. Metamorphic rocks can be classified according to composition and texture. Foliated rocks are banded metamorphic rocks that form when minerals realign as the result of pressure from opposing sides.

What is the color of a metamorphic rock?

It is usually gray in igneous rocks; gray, white, yellow, or red in sedimentary rocks; and gray or white in metamorphic rocks.

Why are metamorphic rocks different colors?

Deep inside the Earth, intense heat and pressure can change rocks into entirely new metamorphic rocks. In fact, the conditions are so extreme, they can change the rock’s texture, color, and the shape of its crystals. This can happen to any rock—igneous, sedimentary, even other metamorphic rocks.
