About Cuprodongchuanite
Formula:
Pb4CuZn2(PO4)4(OH)2
Crystal System:
Triclinic
Member of:
Name:
Named for being the copper analogue of dongchuanite.
Type Locality:
Isostructural with:
The Cu analogue of dongchuanite. Unique combination of elements (at the upload time).
Both dongchuanite and cuprodongchuanite occurs in similar parageneses in the Dongchuan district, China. Cuprodongchuanite is the most common of these two minerals, and the green color can be diagnostic. Nevertheless, these two minerals form a continuous series, and may in many cases be difficult to distinguish without a chemical analysis. Therefore, all photos not specifying how the mineral was identified has been put in the dongchuanite group gallery.
