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 lowest grade of foliated metamorphic rock?
Slate.
How do you classify metamorphic rocks?
Metamorphic rocks are classified as being foliated or being non-foliated. Foliated metamorphic rocks have visible banding or sheet-like layering. Slate, phyllite, gneiss, and schist are foliated metamorphic rocks. Non-foliated metamorphic rocks do not display banding or layering. Marble and quartzite are non-foliated metamorphic rocks. Metamorphic rocks can also be classified as either regional metamorphic rocks or contact metamorphic rocks, depending on their method of formation.
What characteristic are most useful for identifying the conditions under which a metamorphic rock was formed?
The most useful characteristics for identifying the conditions under which a metamorphic rock was formed include its mineral composition, texture, and foliation. The presence of specific minerals, such as garnet or kyanite, can indicate the temperature and pressure conditions during formation. Additionally, the texture, whether foliation or non-foliated, provides insight into the directional pressure and the environment of metamorphism. Understanding these features helps geologists determine the metamorphic grade and the tectonic setting of the rock.
How are igneous and metamorphic rocks related?
Both gneiss and migmatite are late-stage, high grade metamorphic rocks.
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.
Does metamorphic rock change?
Metamorphic rock can undergo a series of changes called degrees of metamorphism, from low-grade to high-grade.
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.
Is amber lily in 8th grade?
No
Gneiss goes through metamorphosis at a higher temperature than slate so it has a higher what?
metamorphic grade
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 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.
Which metamorphic facies represents the highest temperature and pressure conditions?
It's eclogite facies.
What can high grade metamorphic progress to?
high grade metamorphism can progress to pressure and weather.
What is the lowest grade of foliated metamorphic rock?
Slate.
What can metamorphic rocks change into?
Greenschist, blueschist, zeolite, granulite and eclogite high grade metamorphic rocks.
How do you classify metamorphic rocks?
