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. For physical and optical identification, it has most of the characteristic properties of biotite.

Phlogopite: Mineral information, data and localities. Named in 1841 by Johann Friedrich August Breithaupt from the Greek φλογωποζ "phlogopos" for "resembling fire", in allusion to the red tint of the original specimens. Mica Group. Biotite-Phlogopite Series. The hydroxyl analogue of Fluorophlogopite and the magnesium analogue of Hendricksite.

From the Greek flogopos - "resembling fire." Comments: Exceptionally well-crystallized wine-colored pseudo-hexagonal crystal of phlogopite on white calcite.

La flogopite o phlogopite, abbreviato col nome di PHL [1], è un minerale appartenente al gruppo delle miche. Lamine a contorno esagonale talora di dimensioni enormi (fino a 2 metri) di colore bruno chiaro o giallastro spesso in pacchetti o aggregate in masse fogliacee.

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".
