Zinkosite

A valid IMA mineral species - grandfathered - questionable
This page is currently not sponsored. Click here to sponsor this page.
Formula:
ZnSO4
Specific Gravity:
4.33
Crystal System:
Orthorhombic
Probably an artificial product, and its occurence in nature (at least at its "type locality") is doubtful (Calvo and Viñals, 2008).
