A coarse-grained metamorphic rock, also known as a medium to high-grade metamorphic rock, is characterized by its large mineral crystals that are visible to the naked eye. This texture typically results from the recrystallization of minerals under high temperature and pressure conditions, often occurring deep within the Earth's crust. Common examples include gneiss and schist, which exhibit distinct banding and foliation due to the alignment of minerals. The coarse grain size indicates that the rock has undergone significant metamorphic processes.
What else can I help you with?
Do metamorphic rock and igneous rock have fine grained and coarse grained?
Yes. Exactly, they do have both, fine grained and coarse grained rocks.
Is quartzite rock fine grained course grained or medium grained?
Coarse
What type of igneous rock has a coarse-grained texture?
pegmaitie
How long it will take coarse grained rock to become fine grained rock?
The period of time involved in the rock cycle which would involve the transformation of a coarse grained rock into weathered, eroded, transported, deposited, and cemented fine-grained sedimentary particles would vary greatly. Suffice it to say the entire process would take many thousands-to-millions of years.
What is the difference between fine-grained and coarse-grained?
Fine grained has larger crystals and coarse grained has smaller crystals
Do metamorphic rock and igneous rock have fine grained and coarse grained?
Yes. Exactly, they do have both, fine grained and coarse grained rocks.
Is rock smooth or rough?
Metamorphic rock can be coarse grained or fine grained.
What word describes a coarse grained banded metamorphic rock?
Gneiss, pronounced 'nice', is a coarse grained banded metamorphic rock.
Like a coarse-grained banded metamorphic rock?
Please.
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.
Is limestone coarse grained or fine grained?
Limestone can be both coarse-grained and fine-grained, depending on its composition and how it formed. Coarse-grained limestone typically contains larger mineral grains visible to the naked eye, while fine-grained limestone has smaller mineral grains that are not easily seen without magnification.
What is meaning the grain of the rock?
fine grained or coarse grained
Name a coarse grained igneous rock with no pyroxene?
Granite is a coarse grained igneous rock without Pyroxene.
Is Peridotite fine or coarse grained?
A peridotite is a dense, coarse-grained igneous rock
What metamorphic rock is formed from greywacke?
Hornfels or gneiss are possible metamorphic rock with a greywacke protolith.
Does slate have abundant coarse-grained mica in it?
Slate typically does not have abundant coarse-grained mica in it. Mica is more commonly found in other metamorphic rocks such as schist and gneiss. Slate is formed from the low-grade metamorphism of shale or mudstone, resulting in a fine-grained, foliated rock without abundant coarse-grained minerals like mica.
Is quartzite rock fine grained course grained or medium grained?
Coarse
