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 is the parent rock of graphitic phyllite?
The parent rock of graphitic phyllite is typically shale or mudstone. During the metamorphic process, these sedimentary rocks undergo changes in temperature and pressure, which lead to the formation of phyllite. The presence of graphite in graphitic phyllite often results from the alteration of organic matter within the parent rock. This metamorphic rock is characterized by its fine-grained texture and shiny, foliated surfaces.
What type of rock was the metamorphic rock schist formed from?
Probably the metamorphic rock phyllite.
What rocks have foliated structure?
"Foliated" rocks are usually metamorphic rocks like phyllite, slate, schist, and gneiss.
Is marbel a mineral?
yes it is a mineral
What is a mineral that is after phyllite and before gneiss?
Not a mineral but a rock. Schist comes asfter phyllite ut before gneiss.
Is phyllite a mineral or a rock?
Phyllite is a type of metamorphic rock, not a mineral. It is formed from the metamorphism of shale or mudstone and has a fine-grained texture with a silky sheen due to the alignment of its minerals.
Is phyllite foliated or unfoliated?
Phyllite is foliated.
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 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.
Which physical characteristic best describes the rock phyllite?
Foliate textire with microscopic mic a crystal
Is phyllite nonfoliated?
No. Phyllite is definitely foliated.
Can gneiss metamorphose into phyllite?
No. Phyllite can metamorphose into schist and then into gneiss.
What is the physical description of phyllite?
Phyllite is a fine-grained metamorphic rock characterized by its silky sheen and flat, sheet-like structure due to the alignment of its mineral grains. It typically has a glossy to dull luster and often displays a pronounced foliation resulting from the parallel alignment of minerals like mica and chlorite. Phyllite can range in color from gray to green or black, depending on the presence of specific minerals.
What is foliated structure?
In geology, a foliated structure refers to a rock or mineral that is composed of thin easily separable layers. Examples of foliated rocks are gneiss, phyllite, schist and slate.
What is the mineralogy of phyllite?
There are many different minerals that can make up the mineralogy of phyllite. These minerals include muscovite,chlorite, or quartz, sometimes phyllite will include garnet, chlorotoid, sodium-mica, or sulfide minerals.
What is Phyllite used for?
Phyllite is a metamorphic rock that is often used as a decorative stone in landscaping and construction. Its attractive appearance and durability make it a popular choice for countertops, flooring, and wall cladding. Additionally, phyllite can also be crushed and used as an aggregate in concrete production.
