About AtopiteHide

Formula:
(Ca,Na)2Sb2(O,F,OH)7
Name:
From the Greek ατοπος for "unusual," in allusion to its rarity.
Stibiconite Group. It is probably identical with "roméite," but contains sodium in substitution for calcium and contains fluorine, unlike roméite in its older definition. Palache et al. (1951) considered it a Na-bearing variety of roméite. Compare fluorcalcioroméite.

Originally reported from Långban, Filipstad, Värmland, Sweden.
