Zinkosite

This page is currently not sponsored. Click here to sponsor this page.
Formula:
ZnSO4
System:
Orthorhombic
Probably an artificial product, and its occurence in nature (at least at its "type locality") is doubtful (Calvo and Viñals, 2008).

Classification of Zinkosite

Questionable/Doubtful
7.AB.10

7 : SULFATES (selenates, tellurates, chromates, molybdates, wolframates)
A : Sulfates (selenates, etc.) without additional anions, without H2O
B : With medium-sized cations
25.5.1

25 : Sulphates
5 : Sulphates of Zn and Hg
