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.
What else can I help you with?
Why Muscovite is lighter then biotite?
Chemical composition determines density. In this case, I think it's safe to implicate iron content.
What minerals does slate have in it?
Slate is mainly composed of the minerals quartz and muscovite or illite
What is the crystal system of schist?
Schist typically belongs to the metamorphic category of minerals and does not have a specific crystal system since it is a foliated rock composed mainly of micaceous minerals. However, the individual minerals within schist, such as muscovite and biotite, usually belong to the monoclinic or hexagonal crystal systems. The foliation in schist is a result of the alignment of these plate-like minerals under directed pressure and temperature conditions during metamorphism.
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 type of crystal habit does muscovite display?
Muscovite generally displays a micaceous crystal habit, of thin flexible sheets.
How are the minerals biotite mica and the Muscovite mica different?
Biotite mica contains iron and/or magnesium, but muscovite mica does not.
What two minerals share the common name mica?
Biotite and Muscovite.
What are the kinds of silicate minerals?
Quartz, Feldspar, Muscovite, Biotite are among most common silicate minerals.
What is the geologic mean of platy mineral?
Platy minerals are micas(muscovite and biotite) and chlorite
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 group is mica in?
Mica is a group of sheet silicate minerals (e.x of micas : Biotite, muscovite)
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 are the soft silicate flakes found in many rocks?
The soft silicate flakes found in many rocks are likely to be mica minerals, such as muscovite or biotite. These minerals have a layered structure that allows them to break into thin flakes or sheets easily. Mica minerals are common in igneous, metamorphic, and sedimentary rocks.
What is the mica mineral symbol?
Muscovite (clear) and Biotite (black) are the commonest mica forms. Fuchsite (green) is an unusual mica containing chromium. Please see the related link below for a listing of the mica group of minerals.
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.
What minerals have only one direction of cleavage?
Some minerals that have only one direction of cleavage include mica (like muscovite), halite (salt), and graphite. Cleavage is the tendency of minerals to break along preferred planes due to their atomic structure.
What mineral has one perfect cleavage muscovite and biotite?
Mica or silicate
