System:Triclinic
Member of:Atacamite Group
Name:For the relation to the other atacamite minerals.
Polymorph of:Atacamite, Botallackite, Clinoatacamite


Visually indistinguishable from clinoatacamite and, to a lesser extent, paratacamite.

Note that a small part of the lot that contained anatacamite was also sold in 2008 as paratacamite (Tony Nikischer information).
