Name:
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. Also, generally the micas on the Phlogopite end (magnesium end) of the Biotite-Phlogopite Series, including Phlogopite, Fluorophlogopite, Eastonite, and Hendricksite.

A wide-spread member of the mica group occurring especially in crystalline, dolomitic marbles associated with spinel, diopside and members of the chondrodite group. Redefined as the OH end-member by the IMA Mica Subcommittee in 1998.
