About Daphnite
Formula:
(Fe,Mg)5Al(Si,Al)4O10(OH)8
A variety of Chamosite
A magnesian variety of chamosite.
Originally reported from Penzance - Ludgvan Area, Mount's Bay District, Cornwall, England, UK.
Used by Hey (1954) in his 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 now considered a variety of chamosite.
