About Brunsvigite
Formula:
(Fe2+,Mg,Al)6(Si,Al)4O10(OH)8
Name:
Named in 1901 by Johannes Fromme for Brunsvig region in Germany where the mineral was found.
A variety of Chamosite
Used by Hey (1954) in his widely used, formal classification of chlorites, for ones with Mg/(Mg+Fe) = 0.25-0.5 and Si = 5.6-6.2 atoms per 8 tetrahedral sites, but now considered a variety of chamosite.
Originally described from Gabbro Quarry (Bärenstein Quarry), Bad Harzburg, Harz Mts, Lower Saxony, Germany.
