Description

Dark black palladinite associated with at least two more minerals, that could not be identified yet. Palladinite has been confirmed by SEM-EDS & P/S-XRD methods. Electron beam analysis shows that there is a small amount of a Pd, Se metal and another yet unidentified Cu-Se-O mineral (clinochalcomenite?) intergrown with the palladinite. 

Analytical data in the analytical section. Palladinate can contain significant Cu amounts.
