Formula:
(K,Na)(Mg,Fe2+,Fe3+,Cu)(Fe3+,Al)(Si,Al)4O10(OH)2
Crystal System:
Monoclinic
A 2M polytype mica, glauconite variety, containing up to 2.02 wt.% CuO and anomalously rich in Na2O (over 6 wt.%) and MgO (over 7 wt.%), by up to 1.13 wt.% FeO.
A common constituent of white sandstones (Weissliegendes) with chalcocite mineralization within the Zechstein Cu deposits of Fore-Sudetic Monocline, Poland. Likely a product of an interaction of ordinary glauconite with Mg,K-bearing brine being at once parental to the Cu mineralization.
