Schist is a metamorphic rock that tends to have larger mineral grains and a more layered structure compared to phyllite. Phyllite is also a metamorphic rock, but it has smaller mineral grains and a more silky sheen due to the alignment of mica minerals.

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 mineral is common in schist and gneiss but not common is slate and phyllite?
The mineral common in schist and gneiss but not common in slate and phyllite is garnet. Garnet typically forms in higher-grade metamorphic rocks such as schist and gneiss due to the increased temperature and pressure conditions necessary for its formation.
What foliated metamorphic rock is texturally intermediate between slate and schist?
Phyllite is a foliated metamorphic rock that is texturally intermediate between slate and schist. It exhibits a greater degree of metamorphism than slate but not as much as schist, resulting in a medium-grain texture with a glossy sheen.
Can you describe the 4 rocks formed by metamorphic grade which are Slate Phyllite Schist and Gneiss?
Slate is a low-grade metamorphic rock characterized by fine-grained foliated structure. Phyllite is intermediate-grade metamorphic rock with a greater degree of crystallization and foliation than slate. Schist is a medium-grade metamorphic rock with visible mineral grains and strong foliation. Gneiss is a high-grade metamorphic rock with distinct banding of light and dark minerals and high crystallization.
What do heat and pressure change shale to?
Heat and pressure change shale into metamorphic rock, specifically slate when exposed to low to moderate levels of heat and pressure, and then further into phyllite, schist, and gneiss as the intensity of heat and pressure increases.
What is after phyllite and before gneiss?
schist
Can gneiss metamorphose into phyllite?
No. Phyllite can metamorphose into schist and then into gneiss.
Rock that can change into schist?
Phyllite.
What is a mineral that is after phyllite and before gneiss?
Not a mineral but a rock. Schist comes asfter phyllite ut before gneiss.
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 mineral is common in schist and gneiss but not common is slate and phyllite?
The mineral common in schist and gneiss but not common in slate and phyllite is garnet. Garnet typically forms in higher-grade metamorphic rocks such as schist and gneiss due to the increased temperature and pressure conditions necessary for its formation.
What are ways to get schist?
Schist is a foliated metamorphic rock. It is formed when mudstone, shale, slate, or phyllite are subjected to higher temperature and pressure.
What foliated metamorphic rock is texturally intermediate between slate and schist?
Phyllite is a foliated metamorphic rock that is texturally intermediate between slate and schist. It exhibits a greater degree of metamorphism than slate but not as much as schist, resulting in a medium-grain texture with a glossy sheen.
What type of rock was the metamorphic rock schist formed from?
Probably the metamorphic rock phyllite.
10 examples of metamorphic rocks?
- Amphibolite - Eclogite - Gneiss - Greenstone - Hornfels - Marble - Migmatite - Phyllite - Quartzite (Metaquartzite) - Schist - Slate - Soapstone
What is name of the rocks?
Not sure what you mean but a few types of Metamorphic rocks are: Marble Slate Phyllite and Schist.
What metamorphic rocks are found in Pennsylvania?
Pennsylvania is home to quartzite, slate, marble, phyllite, gneiss, and schist
