What is Mica? How is Mica Formed? What is it is Used For ...

26-04-2020· How is Mica Formed? Micas do originate as a result of diverse processes and several conditions. There are various processes of formation that includes deposition by fluids derived from magmatic activities, consolidating magmas, deposition of fluid circulating by both contact and regional metamorphism, and also by alternate process. They are even caused by weathering of feldspar and minerals.

Mica - Wikipedia

The mica group of sheet silicate (phyllosilicate) minerals includes several closely related materials having nearly perfect basal cleavage.All are monoclinic, with a tendency towards pseudohexagonal crystals, and are similar in chemical composition.The nearly perfect cleavage, which is the most prominent characteristic of mica, is explained by the hexagonal sheet-like arrangement of its atoms.

Mica Minerals are Major Rock Forming Minerals

Mica Minerals are Major Rock Forming Minerals. Mica minerals are major rock forming minerals found in gneiss, schist and granite. The mica group includes muscovite mica and biotite mica. They usually form in layers of sediment on ocean floors. Weathering of continental rocks breaks large and small chunks of rock off the larger older rocks.

Phlogopite - Wikipedia

Phlogopite is a yellow, greenish, or reddish-brown member of the mica family of phyllosilicates.It is also known as magnesium mica.. Phlogopite is the magnesium endmember of the biotite solid solution series, with the chemical formula KMg 3 AlSi 3 O 10 (F,OH) 2.Iron substitutes for magnesium in variable amounts leading to the more common biotite with higher iron content.
