What is the difference between metamorphic grade and metamorphic facies?

∙ 10y ago
A metamorphic grade takes into account only the change in temperature while a metamorphic facies is more specific by showing the change in temperature in relation to the change in pressure and depth. There are three grades: low (250°C-400°C), intermediate (400°C-600°C) and high (above 600°C). Although there are many facies, the major ones are zeolite, hornfels, greenschist, amphibolite, blueschist, eclogite, and granulite. This allows for geologist to easily locate where a metamorphic rock was formed.

What sequences describes the metamorphic changes in a shale with increasing metamorphic grade?

What is the difference between schist and phyllite?
Texture and metamorphic grade. Schist has visible crystals, while phyllite has crystals too small to be seen with the eye or barely seen. This is a result of schist having higher grade metamorphism.
Can you describe the 4 rocks formed by metamorphic grade which are Slate Phyllite Schist and Gneiss?
Four rocks formed by metamorphic grade are slate, phyllite, schist and gneiss. Slate and pnyllite are low grade; schist is a medium grade; and gneiss is a high grade rock.
What is the difference between low grade and high grade metamorphism?
One is high and one is low.
What is the difference between conglomerate and gneiss?
Conglomerate is a clastic sedimentary rock that has rounded pebbles included among its clasts. Gneiss is a high-grade foliate metamorphic rock characterized by alternating light and dark bands. It forms from the metamorphism of granite or schist.
Which metamorphic facies represents the highest temperature and pressure conditions?
It's eclogite facies.
What is the texture of hornfels?
I too would like an answer to this question as it seems hornfels could be of varying grade dependant on the temperature. The facies of contact metamorphism progress in temperature at relatively low pressure from the Albite-Epidote Hornfels Facies to the Hornblende Hornfels Facies, to the Pyroxene Hornfels Facies. It seems that hornfels do have differant grades.

What is the metamorphic grade of gneiss?
Gneiss is usually considered a high grade metamorphic rock (although there are some weird exceptions).
What are difference between grade a b and c material?
The main difference is in between grade A,B & C IS THE CARBON CONTAIN OF THE MATERIALS.

What is the difference between schist and phyllite?
Texture and metamorphic grade. Schist has visible crystals, while phyllite has crystals too small to be seen with the eye or barely seen. This is a result of schist having higher grade metamorphism.
Does metamorphic rock change?
Metamorphic rock can undergo a series of changes called degrees of metamorphism, from low-grade to high-grade.
What is a metamorphic rock formed from a shale?
Slate. Slate is a low grade metamorphic rock derived from shale or mudstone.
Can metamorphic rocks from from other metamorphic rocks?
Yes. Most likely it would become a metamorphic rock of higher grade. Slate is a low grade metamorphic rock. With increased heat and pressure it will become schist, a high grade metamorphic rock.
What is the difference between grade D and grade A mild steel plate?
A B C after that grade D
What is the difference between grade 11 and grade 12?
A year and a year of maturity. The difference in a year of growing up is huge.
