Phlogopite: The Brown Mica, Rich in Magnesium

Phlogopite is a common member of the mica mineral group. It has a chemical composition of KMg 3 (AlSi 3 O 10 ) (F,OH) 2. Crystals of phlogopite are often brown, but can be yellow, green or reddish brown. It is sometimes called "the brown mica". When a phlogopite crystal is split into very thin sheets, the sheets are transparent, lustrous ...

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.
