Member of:Quintinite Group > Hydrotalcite Supergroup
Name:Named in 1997 by George Y. Chao and Robert A. Gault for Charles [1917-2003] and Marcelle [September 19, 1918 - 2003] Weber, amateur mineralogists of Guilford, Connecticut, USA, who contributed extensively to the knowledge of Mt. Saint-Hilaire, and who also found the mineral.


Found as the polytypes Charmarite-2H and Charmarite-3T.

Classification of Charmarite

IMA status:Approved 1998
Explanation of status:As of 1998, polytypes are no longer regarded by IMA as separate species, so Charmarite regains its species status.
