Claraite

This page is currently not sponsored. Click here to sponsor this page.
Formula:
(Cu,Zn)3(CO3)(OH)4 · 4H2O
Name:
For the type locality, the Clara mine.
Note: the originally published formula is erroneous - claraite contains essential As and S (U. Kolitsch, 2007-2015, to be published; Kolitsch, 2012; Putz et al., 2012).


Classification of Claraite

Approved
5.DA.30

5 : CARBONATES (NITRATES)
D : Carbonates with additional anions, with H2O
A : With medium-sized cations
16b.4.3.1

4 : AmBn(XO3)pZqxH2O & with (m+n):p = 3:1
11.6.6

11 : Carbonates
6 : Carbonates of Zn and Cd
