What rock forms at the lowest grade of regional metamorphism?
Zeolite.
Is soapstone regional or contact metamorphism?
Very low grade regional metamorphism.
Which kind metamorphic rock most likely form in the high temperatures and pressures?
At the highest temperatures and pressures, high-grade metamorphism occurs forming high-grade metamorphic rocks. The main example of this is gneiss.
What is the texture used to identify the highest degree of regional metamorphism in a foliated rock?
Gneissic texture is used to identify the highest grade of metamorphic rock that still displays foliation. Granulite is the highest grade metamorphic rock, period, but does not display foliation due to the instability of sheet silicates.
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.

Slate is associated with high-grade metamorphism?
No Slate is associated with a low-grade metamorphism
What is low-grade metamorphism?
Alow-grade metamorphism is when the rock turns to shale,a sedimentary rock then to slate

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 type of coal has undergone the greatest change?
Anthracite coal has been through low-grade metamorphism to become the highest grade of coal. This type of coal has the highest carbon count and the fewest impurities of any other type of coal.
If metamorphism causes a rock to melt would the rock that results still be consider a metamorphic rock?
=== === Metamorphism does not cause a rock to melt. If a rock melts, then solidifies, it is by definition an igneous rock. There are rocks called granulites which represent the highest grade of metamorphism, and some may have experienced a partialmelting.
Is Kyanite is an index mineral of a low grade metamorphism?
No, kyanite is an indicator of high pressure metamorphism.
What can high grade metamorphic progress to?
high grade metamorphism can progress to pressure and weather.
