Muscovite calcite schist in California?
Muscovite calcite schist in California is a metamorphic rock that typically forms from the alteration of sedimentary rocks like limestone or dolomite. It is characterized by the presence of muscovite mica, calcite, and schistosity (foliation). This rock type is commonly found in the metamorphic terranes of the Sierra Nevada Mountains and northern California.
What is the origin of a gneiss rock?
Gneiss is a metamorphic rock and its parent rock (protolith) could be a granite or schist.
What is the rock category of schist?
A schist is a metamorphic rock.
What is the most common mineral in schist?
The most common minerals in gneiss are quartz, potassium feldspar, and sodium feldspar. Smaller amounts of muscovite, biotite and hornblende are common. Gneiss can also form from gabbro or shale.
What are the parent rocks of the metamorphic rock?
Parent rocks of metamorphic rocks can include sedimentary rocks, igneous rocks, and other metamorphic rocks. Some common parent rocks are shale, granite, and basalt. The mineral composition and texture of the parent rock influence the characteristics of the resulting metamorphic rock.
Muscovite calcite schist in California?

It is characterized by the presence of muscovite mica, calcite, and schistosity (foliation). This rock type is commonly found in the metamorphic terranes of the Sierra Nevada Mountains and northern California.
What is a metamorphic rock made from schist?
Gneiss is a metamorphic rock formed when intense heat and/or pressure is applied to it's parent rock schist.
Mineralisation of schist belt?
Biotite, muscovite, chlorite, talc, garnet, and kyanite are common in schist.
What is the origin of a gneiss rock?
Gneiss is a metamorphic rock and its parent rock (protolith) could be a granite or schist.
Is schist the same as mica schist?
No, schist is a metamorphic rock type characterized by strong foliation, while mica schist is a specific type of schist that contains a high proportion of mica minerals like muscovite or biotite. Mica schist has a distinct shiny appearance due to the abundance of mica minerals.
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.
Most common form of Mica occurring in Gneiss granite and schist?
muscovite
Where is muscovite found?
Muscovite is found wherever igneous and metamorphic rocks are found and is mined in New England, North Carolina, South Dakota, Colorado, Utah, Massachusetts, Virginia, New Mexico, India and Brazil. A Muscovite is also a native of Moscow
Which mineral is responsible for the strong foliation in a schist?
The mineral responsible for the strong foliation in schist is usually mica (such as biotite or muscovite). These minerals have a planar structure that aligns during the metamorphic process, creating the foliation planes in the rock.
What rocks make schist?
Schist comes from shale. It is laminated , flaky, and found in parallel layers. The minerals in this rocks that have crystallized from the parent rock are visible.
What kind of rock is schist rock?
Schist is a metamorphic rock.
What is the rock category of schist?
A schist is a metamorphic rock.
