It varies some metamorphic rocks are fine grained (eg slate) and others have very large crystals (eg an augen gneiss).
What else can I help you with?
Is Gneiss a sedimentary metamorphic or igneous rock?
Gneiss is a metamorphic rock that forms from the recrystallization of pre-existing rocks under high temperature and pressure conditions. It is characterized by its banded texture and coarser grain size compared to other types of metamorphic rocks.
What is stronger igneous or metamorphic rocks?
In general, igneous rocks tend to be stronger than metamorphic rocks due to their crystalline structure and lack of weaknesses like cleavage planes that are common in metamorphic rocks. However, the specific strength of a rock depends on factors such as composition, grain size, and how the rock has been altered by geological processes.
What is grain according to geologists?
Grain refers to particle or crystal size in rock.
What else does rock texture include besides grain size and arrangement?
Grain shape.
Which metamorphic rock has an even grain and can be cut into thin stones or easily carved?
i think what you are looking for is slate because it is a layered rock and the layers are very thin.

What type of metamorphic rock has a grain texture?
Because of the gravity ..

What type of metamorphic rock has a random grain texture?
Because of the gravity ..
Grain size of metamorphic rock increases in the process of .?
Grain size increases in the process of recrystallization.
What is rock that is changed by heat pressure or chemical change?
Metamorphic rocks have been changed by heat or pressure. This can be a change in size, shape, or arrangement of minerals.
What rock are classifed by crystal size mineral content and where they form?
it is metamorphic rock
What is a small grain size rock?
clay
What sedimetary rock has the smallest grain size?
Shale is a sedimentary rock that typically has the smallest grain size due to its fine-grained and compacted nature.
Does the rocks pigments give the rock its texture?
No, the texture of a rock is determined by its mineral composition, grain size, and how the rock formed (igneous, sedimentary, or metamorphic). Pigments refer to the coloration of a rock, which can be caused by the presence of specific minerals or impurities. Texture and pigmentation are separate characteristics of rocks.
What is grain according to geologists?
Grain refers to particle or crystal size in rock.
What process changes the grain size of a metamorphic rock?
In order to decrease the pressure within our respiratory tract, we have to expand our container. Our container is basically our thorax. If we can expand our thorax, the air pressure within our thoracic cavity will fall, and air will rush into our respiratory tract. The diaphragm is our primary means to increase our thoracic cavity
