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 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.
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.
What is the difference between schist and phyllite?
Texture and metamorphic grade. Schist has visible crystals, while phyllite has crystals too small to be seen with the eye or barely seen. This is a result of schist having higher grade metamorphism.
What are the types of rock metamorphism?
Types of metamorphism are Contact Metamorphism Regional Metamorphism Cataclastic Metamorphism Hydrothermal Metamorphism Burial Metamorphism Shock Metamorphism (Impact Metamorphism)
