A valid IMA mineral species

About MinohliteHide

This section is currently hidden. Click the show button to view.

Formula:

(Cu,Zn)7(SO4)2(OH)10 · 8H2O

Cu:Zn is somewhat variable.

Name:

Named after Minoh City, where it was discovered.

Chemically and structurally related to schulenbergite.
Minohlite and schulenbergite may be intimately intergrown (Orlandi, 2013).
If minohlite is heated >50°C, it turns into schulenbergite (Orlandi, 2013).
