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 is the difference between slate and phyllite?

Slate is a fine-grained metamorphic rock formed from the low-grade metamorphism of shale or mudstone, while phyllite is a more intermediate-grade metamorphic rock formed from the metamorphism of slate. Phyllite has a more pronounced foliation and sheen due to increased metamorphic pressure and temperature compared to slate.


Can you describe the 4 rocks formed by metamorphic grade which are Slate Phyllite Schist and Gneiss?

Slate is a low-grade metamorphic rock characterized by fine-grained foliated structure. Phyllite is intermediate-grade metamorphic rock with a greater degree of crystallization and foliation than slate. Schist is a medium-grade metamorphic rock with visible mineral grains and strong foliation. Gneiss is a high-grade metamorphic rock with distinct banding of light and dark minerals and high crystallization.


Gneiss goes through metamorphosis at a higher temperature than slate so it has a higher what?

metamorphic grade


What refers to how much the metamorphic rock differs from parent rock?

Metamorphic grade refers to the degree of metamorphic change a rock has undergone compared to its parent rock. It encompasses changes in mineralogy, texture, and structure that occur during the metamorphic process.


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.

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.

Does metamorphic rock change?

Metamorphic rock can undergo a series of changes called degrees of metamorphism, from low-grade to high-grade.
