Unnamed (Cu-Zn Chloride Hydroxide)

This page is currently not sponsored. Click here to sponsor this page.
Formula:
CuZnCl(OH)3
Crystal System:
Monoclinic
Member of:
Atacamite Group
Isostructural with:
Botallackite
Anthropogenic substance found on copper mining artifact from Rowley mine, Maricopa County, Arizona, USA. The most Zn-rich representative of the atacamite group so far. The presence of the phase is in an opposition to the previous report of botallackite being resistant to Zn substitution.

The phase differs from botallackite in complete replacement of Cu by Zn in the M1 site.
