A schistose texture.
What else can I help you with?
When mineral grains flatten and line up in layers a metamorphic rock has a?
A schistose texture.
When metamorphic rock has banded texture with minerals grains that are arranged in layers it is called?
Metamorphic rocks with a layered or banded look are referred to as foliated.
When mineral grains in a metamorphic rock do not form layers the rock has what texture?
no texture
A metamorphic rock that has grains arranged in parallel layers has a what texture?
It has a foliated texture.
What is a metamorphic rock that has parallel alignment of mineral grains?
Schist is a metamorphic rock that exhibits parallel alignment of mineral grains, giving it a foliated appearance. This alignment is typically a result of regional metamorphism where intense pressure and temperature conditions cause the minerals to recrystallize in a preferred orientation.
Which characteristic determines the category of metamorphic rock?
The texture and mineral composition of a rock are the characteristics that determine its category in metamorphic rocks. Texture refers to the arrangement of mineral grains, while mineral composition indicates the types of minerals present and their abundance.
Is metamorphic rock rough or smooth?
Metamorphic rock can vary in texture, with some being rough due to the presence of mineral grains and others being smooth due to recrystallization of minerals during the metamorphic process. The texture of metamorphic rock depends on factors such as the original rock type and the intensity of heat and pressure.
What do metamorphic rocks with a non-foliated texture show metamorphic changes involve?
Metamorphic rocks with a non-foliated texture show that the metamorphic changes involved did not result in the development of a preferred alignment of mineral grains. This indicates that the rocks were subjected to directed pressure or high temperatures without causing the minerals to align into layers. Examples of non-foliated rocks include marble and quartzite.
When a mineral grains in a metamorphic rock do not form layers the rock has a?
no texture
A metamorphic rock can be classified according to its?
A metamorphic rock can be classified according to its texture, mineral composition, and metamorphic grade. Texture refers to the size and arrangement of mineral grains, while mineral composition indicates the minerals present. Metamorphic grade refers to the temperature and pressure conditions under which the rock formed.
What kind of metamorphic has its minerals grains arrange in planes or band?
Metamorphic rock with mineral grains arranaged in bands or lamellar planes are called foliated metamorphic rocks.
Which process changes the space between the grains in a metamorphic rock?
Recrystallization is the process that changes the space between the grains in a metamorphic rock. It involves the rearrangement of minerals within the rock to form new crystal structures, often resulting in a more compact and dense texture.
