About Manganophyllite
Formula:
K(Fe,Mg,Mn)3AlSi3O10(OH)2
Colour:
Dark brownish
Crystal System:
Hexagonal
First Recorded Locality:
A Mn-rich variety of biotite.
A study of Knurr and Bailey (1986) showed that manganophyllite contains divalent Mn, unlike alurgite (Mn-bearing muscovite) which contains trivalent Mn.
Originally described from Harstigen Mine, Pajsberg, Filipstad, Värmland, Sweden.
