Both are platy, silicate, mica group minerals with perfect cleavage in one direction.
Biotite mica is dark, muscovite mica is light in color.
Biotite is dark, muscovite is light
Biotite and Muscovite.
They are most likely muscovite or biotite mica.
Many types of mica are known: biotite, lepidolite, muscovite, phlogopite, zinnwaldite, clintonite, illite, phengite.
Biotites comprise a range of different black mica minerals with different chemical composition and physical properties.
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.
K-feldspar, Na-feldspar and Quartz Muscovite biotite.
Biotite mica contains iron and/or magnesium, but muscovite mica does not.
micas such as muscovite, biotite
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.
Mica or silicate
Iron.
Biotite and Muscovite.
Biotite is definitely a mineral. It's in the same family as muscovite, another mineral in the mica family.
Biotite mica contains iron and/or magnesium, but muscovite mica does not.
Platy minerals are micas(muscovite and biotite) and chlorite
Mica Is Not A Renewable Resource Because Think About When Muscovite Mica And Biotite Mica Go Extinct. Muscovite Mica And Biotite Mica Are Both Types To Make Mica, And If That Goes Extinct Then Mica Will Be Extinct Too.
Biotite, muscovite, chlorite, talc, garnet, and kyanite are common in schist.
