What metamorphic grade does the mineral sillimanite belong to?
Sillimanite is an index mineral for high temperature and variable pressure metamorphism.
What is graphite schist?
It is a medium-grade metamorphic rock with a preponderance of the platy mineral graphite.
What is the metamorphic grade of gneiss?
Gneiss is typically associated with high-grade metamorphism, which means that it has undergone intense heat and pressure to form distinct banding of minerals. This places gneiss in the high-pressure and high-temperature conditions of the regional metamorphic grade.
Different types of metamorphic rocks are distinguished by the?
Different types of metamorphic rocks are distinguished by the minerals present, the degree of metamorphism they have undergone, and their texture or fabric. Texture refers to the size, shape, and arrangement of mineral grains within the rock, while the degree of metamorphism can range from low-grade (such as slate) to high-grade (such as gneiss).
How are Different types of metamorphic rocks distinguished?
The mineralogy (i.e. the types of minerals present within the rock) and also the texture of the rock (i.e. the size, arrangement and orientation of mineral grains within the rock) along with it's structure (the presence of features such as foliation and cleavage).
What metamorphic grade does the mineral sillimanite belong to?
Sillimanite is an index mineral for high temperature and variable pressure metamorphism.
What kind of rock is garnet?
Garnet is a mineral most often found in high grade metamorphic rock.
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.
What can high grade metamorphic progress to?
high grade metamorphism can progress to pressure and weather.
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 is graphite schist?
It is a medium-grade metamorphic rock with a preponderance of the platy mineral graphite.
Does metamorphic rock change?
Metamorphic rock can undergo a series of changes called degrees of metamorphism, from low-grade to high-grade.
What is the metamorphic grade of gneiss?
Gneiss is typically associated with high-grade metamorphism, which means that it has undergone intense heat and pressure to form distinct banding of minerals. This places gneiss in the high-pressure and high-temperature conditions of the regional metamorphic grade.

What can metamorphic rocks change into?
Greenschist, blueschist, zeolite, granulite and eclogite high grade metamorphic rocks.
Is epidote an igneous rock?
Epidote is not an igneous rock; it is a mineral that typically forms in metamorphic rocks and is sometimes found in igneous rocks as an accessory mineral. It is often associated with the alteration of plagioclase feldspar and can occur in high-grade metamorphic environments. Epidote is known for its distinctive green color and is commonly used as a gemstone.
