Bahariyaite
A valid IMA mineral species
This page is currently not sponsored. Click here to sponsor this page.
Formula:
KMnO4
Crystal System:
Orthorhombic
Type Locality:
Supposed natural potassium permanganate, i.e., potassium manganate(VII). First example of the +7 oxidation state of manganese reported in nature.
First found on the western edge of the Bahariya Oasis, Western Desert, Egypt.
As of April 2023 this still has not been published. It remains a highly doubtful natural occurrence and is quite possibly anthropogenic in origin.
