What else can I help you with?
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
What is the most widely distributed metamorphic rock?
The most widely distributed metamorphic rock is schist. Schist forms from the metamorphism of rocks such as shale or slate, and it is characterized by its foliated texture composed of platy minerals like mica. Schist is found in many regions worldwide, occurring in areas where regional metamorphism has taken place.
Is shist porous?
Yes, schist is typically porous due to its layered composition of minerals. The porosity of schist can vary depending on the specific mineral content and the degree of metamorphism it has undergone.
What is mica shisht made of?
Mica schist is a metamorphic rock primarily composed of mica, quartz, and feldspar. It forms through the metamorphism of shale or clay-rich rocks under high temperature and pressure conditions. Mica schist typically has a foliated texture due to the alignment of mica crystals during metamorphism.
How old is schist rock?
Schist rock is a type of metamorphic rock that forms deep within the Earth's crust. The age of schist rock can vary widely, as it depends on when the rock was formed through the process of metamorphism. In general, schist rock can range in age from hundreds of millions to billions of years old.

What does schist begin as?
Schist typically begins as a metamorphic rock called shale, which is composed of clay and other fine-grained sedimentary minerals. Through the process of metamorphism, intense heat and pressure cause the minerals in the shale to recrystallize, forming the distinct foliated structure and mineral composition that characterize 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 is the most widely distributed metamorphic rock?
The most widely distributed metamorphic rock is schist. Schist forms from the metamorphism of rocks such as shale or slate, and it is characterized by its foliated texture composed of platy minerals like mica. Schist is found in many regions worldwide, occurring in areas where regional metamorphism has taken place.
What type of metamorphism contact or regional would result in a schist explain your choice?
Regional metamorphism would result in the formation of schist. Schist is a metamorphic rock that forms under high pressure and temperature conditions over a large area, which is characteristic of regional metamorphism. This process causes the original minerals in the rock to recrystallize into new minerals, giving schist its foliated texture.
Which characteristic of rocks tends to increase as the rocks are metamorphosed?
Foliation, or the alignment of mineral grains in a preferred direction, tends to increase as rocks experience metamorphism. This results in a layered appearance in metamorphic rocks, such as schist and gneiss.
Is shist porous?
Yes, schist is typically porous due to its layered composition of minerals. The porosity of schist can vary depending on the specific mineral content and the degree of metamorphism it has undergone.
What is the difference between schist and marble?
Schist is a metamorphic rock with medium to coarse grain size that typically forms from the metamorphism of shale or mudstone. Marble is a metamorphic rock primarily composed of calcite or dolomite minerals that forms from the metamorphism of limestone. Schist has a foliated texture, while marble has a non-foliated texture.
What lists the rocks in order of increasing grain size and increasing grade of metamorphism?
The list that orders rocks in increasing grain size and increasing grade of metamorphism is: shale (fine-grained) - slate (fine-grained) - phyllite (medium-grained) - schist (medium to coarse-grained) - gneiss (coarse-grained).
What type of metamorphism would result in a schist?
Regional metamorphism would result in the formation of schist. This type of metamorphism occurs under high pressure and temperature conditions over large areas, such as during the collision of tectonic plates. Schist forms from the recrystallization of existing rocks like shale or slate, resulting in distinct foliation and often containing minerals like mica or quartz.
How does metamorphism affect basalt?
Metamorphism can cause basalt to undergo changes in mineral composition and texture, forming new minerals like chlorite, epidote, or amphibole. The original basalt can recrystallize into a denser, harder rock known as greenstone due to metamorphic heat and pressure. The degree of metamorphism can vary, with low-grade metamorphism likely resulting in minor changes, while high-grade metamorphism can drastically alter the basalt's appearance.
Describe the metamorphism of shale and the rock sequence involved in that metamorphism?
Shale undergoes low-grade metamorphism to form slate, then phyllite, schist, and finally gneiss as metamorphic grade increases. This sequence is a result of increasing temperature and pressure conditions during metamorphism, leading to the formation of different minerals and textures in the rock. The progression from shale to gneiss represents a range of metamorphic grades and the increasing intensity of metamorphic processes.
