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 is the freezing point of biotite?
Biotites comprise a range of different black mica minerals with different chemical composition and physical properties.
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.
Is biotite magnetic?
no,biotite is not attracted to magetic forces (its not attracted to magnet)
What are the properties of granite?
K-feldspar, Na-feldspar and Quartz Muscovite biotite.
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.
How can you distinguish between two members of the mica family?
To distinguish between two members of the mica family, you can examine their physical properties such as color, luster, and cleavage. For example, muscovite is typically colorless to light brown and has a pearly luster, while biotite is darker, often black or brown, with a glassy luster. Additionally, you can assess their cleavage, as both exhibit perfect basal cleavage but may differ in the angle of cleavage planes. Finally, checking their hardness on the Mohs scale can also help differentiate them, with muscovite being softer than biotite.
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.
What two minerals share the common name mica?
Biotite and Muscovite.
What mineral has one perfect cleavage muscovite and biotite?
Mica or silicate
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 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.
