What type of minerals are biotite and muscovite?
Generally referred to as micaceous minerals, biotite and muscovite are silicate minerals having perfect basal cleavage. They both contain most of the same elements, just in different quantities. However, biotite is soluble in sulfuric acid and has iron and magnesium in it, where muscovite does not. They can be found in all types of rock.
How does silica from molten material affect the color of igneous rock?
The majority of minerals associated with igneous rocks are silicates. It is the proportion of certain silicate minerals that affects the color of igneous rocks. Igneous rocks that are high in orthoclase feldspar, quartz, and muscovite mica will be lighter in color than igneous rocks that are higher in olivine, pyroxene, amphibole, and biotite mica.
What are the elements found in slate?
Slate is mainly composed of quartz and muscovite or illite, often along with biotite, chlorite, hematite, and pyrite and, less frequently, apatite, graphite, kaolin, magnetite, tourmaline, or zircon as well as feldspar.
What type of crystal habit does muscovite display?
Muscovite generally displays a micaceous crystal habit, of thin flexible sheets.
Which mineral is commonly found in the three matamorphic rocks slate schist and gneiss?
granite
How are the minerals biotite mica and the Muscovite mica different?
Biotite mica contains iron and/or magnesium, but muscovite mica does not.
What element is present in biotite mica that is not present in muscovite mica?
Iron is present in biotite mica but not in muscovite mica.
What physical properties distinguish biotite from muscovite?
Biotite is typically darker in color compared to muscovite, and it has higher iron and magnesium content, which gives it a higher specific gravity. Biotite also exhibits stronger pleochroism compared to muscovite, meaning it shows more noticeable color variations when viewed from different angles. Additionally, biotite has a higher tendency to cleave into thin, flexible sheets compared to muscovite.

What mineral has one perfect cleavage muscovite and biotite?
Mica or silicate
What two minerals share the common name mica?
Biotite and Muscovite.
Is muscotive mica more mafic and less dense than biotite mica?
Muscovite mica is generally less mafic and less dense than biotite mica. Muscovite is a potassium aluminum silicate, while biotite contains iron and magnesium, giving it a more mafic composition. As a result, biotite is denser than muscovite, which typically has a lower specific gravity due to its higher aluminum and silicon content.
What are the properties of granite?
K-feldspar, Na-feldspar and Quartz Muscovite biotite.
What is the geologic mean of platy mineral?
Platy minerals are micas(muscovite and biotite) and chlorite
Mineralisation of schist belt?
Biotite, muscovite, chlorite, talc, garnet, and kyanite are common in schist.
What group is mica in?
Mica is a group of sheet silicate minerals (e.x of micas : Biotite, muscovite)
Is biotite a mineral or non-mineral?
Biotite is definitely a mineral. It's in the same family as muscovite, another mineral in the mica family.
