What is low-grade metamorphism?
Alow-grade metamorphism is when the rock turns to shale,a sedimentary rock then to slate
Slate is associated with high-grade metamorphism?
No Slate is associated with a low-grade metamorphism
Is soapstone regional or contact metamorphism?
Very low grade regional metamorphism.
What is the difference between low grade and high grade metamorphism?
One is high and one is low.
Is Kyanite is an index mineral of a low grade metamorphism?
No, kyanite is an indicator of high pressure metamorphism.
Does metamorphic rock change?
Metamorphic rock can undergo a series of changes called degrees of metamorphism, from low-grade to high-grade.
What are the Levels of metamorphism?
Metamorphic rock is given a grade from low to high depending on the amount of change it has undergone.
High grade metamorphism?
The high grade metamorphism refers to the metamorphism that takes place at temperatures that are greater than 320 degree Celsius. The high grade metamorphism also takes place at relatively high pressure.
What Metamorphic rock is the result of lowest level of compaction applied to shale?
Slate is the product of low grade metamorphism of shale.
How was talc formed?
Talc is formed by the hydrothermal alteration of ultrabasic rocks, or low grade thermal metamorphism of siliceous dolomites.
Are some rocks metamorphic AND sedimentary?
No. If a sedimentary rock has undergone even a low grade metamorphism, it is considered a metamorphic rock.
What are the three main types of metamorphism Compare and contrast the factors that cause each type?
The three main types of metamorphism are: Regional Metamorphism Contact Metamorphism Hydrothermal metamorphism Regional metamorphism is caused when high temperature and pressure affect large regions of Earths crust, It can range from low grade to high grade. It causes folded rock layers. Contact Metamorphism is when molten material comes in contact with solid rock. High temperature and moderate to low pressure from mineral assemblages. Metamorphic effects decrease with distance. Hydrothermal Metamorphism is when very hot water reacts with rock and alters its chemical and mineral composition. As hot fluids migrate in and out of the rock during metamorphism the original mineral composition and texture of the rock change.
