What is the hardness of biotite mica?
Biotite mica has a Mohs hardness of 2.5-3.0.
Is biotite magnetic?
no,biotite is not attracted to magetic forces (its not attracted to magnet)
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 two minerals share the common name mica?
Biotite and Muscovite.
What minral is also know as black mica?
Mineral.spell check helps. not fools gold.Granite is a black mica, quartzite if dark is also a black mica also specifically biotite. chemical formula K(Mg,Fe)3(Al,Fe)Si3O10(OH)2
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 is the chemical formula for mica var?
If you think to biotite the chemical formula is:K(Mg,Fe)3AlSi3O10(F.OH)2
What is the hardness of biotite mica?
Biotite mica has a Mohs hardness of 2.5-3.0.
What mineral is known as black mica?
Black mica is also known as biotite. It is a common phyllosilicate mineral that is part of the mica group. Biotite is typically black or dark brown in color and is composed of potassium, iron, magnesium, aluminum, silicon, and hydrogen.
Where is biotite mico mined?
Biotite mica is mined in various countries including India, South Africa, Brazil, and the United States. India is one of the leading producers of biotite mica in the world.
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.
Is biotite magnetic?
no,biotite is not attracted to magetic forces (its not attracted to magnet)
Why is biotite not able to be seen?
Biotite is a form of mica, and can be seen without difficulty in the right kind of rocks.
What is a biotite?
A biotite is a variety of dark brown mica, a mixed aluinosilicate and fluoride of potassium, magnesium and iron.
What group is mica in?
Mica is a group of sheet silicate minerals (e.x of micas : Biotite, muscovite)
Is mica a renewable resource?
Mica itself is a mineral resource, and minerals are generally considered non-renewable as they are finite and cannot be replaced on a human timescale. The extraction of mica can also have negative environmental impacts if not managed sustainably.
