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 rock forms at the highest grade of regional metamorphism?

Granulite forms at the highest grade of regional metamorphism. It is a high-grade metamorphic rock primarily composed of minerals such as pyroxene and plagioclase feldspar. Granulite typically forms under high temperatures and pressures deep within the Earth's crust.


Which kind metamorphic rock most likely form in the high temperatures and pressures?

High temperatures and pressures are associated with the formation of regional metamorphic rocks such as schist and gneiss. These rocks form deep within the Earth's crust where tectonic forces are intense, leading to the recrystallization of minerals and the development of foliation.


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.


Can a metamorphic rock become further metamorphic?

Yes, additional pressure and heat will lead to further metamorphism. The reference used to describe this is called the 'degree of metamorphism'. For instance, the sedimentary rock shale can become the low grade metamorphic rock slate. In the next degree of metamorphism, slate can become phyllite. Phyllite can then become schist, and finally gneiss. Migmatite is the highest grade metamorphic rock, but has been partially melted.


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.

Which metamorphic rocks are mostly likely to have formed at the highest temperatures and pressures?

Gneiss is a Plutonic metamorphic rock which is formed under high pressure and temperature condition at Katazone or Lower Zone.


How does metamorphism change coal into anthracite?

Metamorphism changes coal into anthracite by subjecting it to high temperatures and pressures over time, causing it to undergo physical and chemical changes. These changes include the removal of impurities and moisture, as well as an increase in carbon content, resulting in the formation of anthracite, which is the highest rank of coal.

How are the highest indivdual mountains shown on a map?

The highest individual mountains are usually shown with a peak symbol or a triangle symbol on a map. The peak symbol typically includes the name and elevation of the mountain, making it easy to identify the highest points on the map.


What type of coal probably formed from the greatest pressure?

Anthracite coal likely formed from the greatest pressure, as it is the highest grade of coal and has undergone the most intense metamorphism.
