Novodneprite (Novodneprit)

Additional Functions

Collectors Summary

Crystal System tetragonal, I42m

Additional information / Summary

Novodneprit ist eng verwachsen mit Anyuiit was die Strukturstudien von Einzelkristallen unmöglich macht.

Novodneprit ist für das Auge unsichtbar. Bei Mineralgrößen um 7 µm ist das Mineral nur unter dem Elektronenmikroskop erkennbar.
