About Daphnite
Formula:
(Fe,Mg)5Al(Si,Al)4O10(OH)8
A Mg-bearing variety of chamosite. The variety bavalite is very similar.
Originally reported from Penzance - Ludgvan Area, Mount's Bay District, Cornwall, England, UK.
Used by Hey (1954) in his then widely used, formal classification of chlorites, for ones with Mg/(Mg+Fe) = 0-0.25 and Si = 5-5.6 atoms per 8 tetrahedral sites, but nowadays considered a variety of chamosite.
