What type of rocks can undergo metamorphism?
All rocks can undergo metamorphism; sedimentary, igneous, and even metamorphic rocks.
At divergent boundaries is what metamorphism results from extrusion of basaltic lava?
A metamorphic rock formed from Basalt is Schist. a.k.a. Green Schist
How does metamorphism affect basalt?
it changes it in to amphibolite and schist
What are the protoliths of Schist and Anthracite coal?
The protolith of schist is typically shale or slate, which undergoes metamorphism to form schist. The protolith of anthracite coal is primarily bituminous coal, which is subjected to higher temperature and pressure conditions during metamorphism to convert into anthracite coal.
What lists the rocks in order of increasing grain size and increasing grade of metamorphism?
slate, phyllite, schist, gneissslate, schist, phyllite
Describe the metamorphism of shale and the rock sequence involved in that metamorphism?
Shale is a sedimentary rock. In increasing metamorphism, the sequence begins with shale and leads to phyllite, schist, then gneiss.
What type of metamorphism contact or regional would result in a schist explain your choice?
Regional. Contact metamorphism is high temperature-low pressure so no mineral alignment occurs, only new mineral growth.
What does schist begin as?
As you increase the temperature and pressure of Shale it metamorphism occurs. It changes in this order: Shale > Slate > Phyllite > Schist > Gneiss > Migmatite
What is the location of schist?
Schist is a form of metamorphic rock in which a sedimentary rock has been subjected to heat and pressure. These change agents will alter the structure of the rock, and will allow / cause the minerals in the rock to change and aggregate. Schist is a very common rock type, but does need the parent rock to have undergone metamorphism.
Which kind of metamorphism occurs next to an intrusion of molten magma?
Contact metamorphism occurs next to an intrusion of molten magma. This type of metamorphism happens when hot magma comes into contact with existing rock, causing the rock to undergo changes in mineralogy and texture due to the heat and pressure.
What type of metamorphism would result in a schist?
Most schists are derived from phyllite, a lower grade metamorphic rock.
What would distinguish marble from Schist?
Marble is a nonfoliated metamorphic rock made of carbonate minerals, particularly calcite. It is formed by the metamorphism or limestone. Gneiss is a foliated metamorphic rock made of silicate minerals such as quartz and feldspars, and micas. It forms from the metamorphism of granite or schist.
