Hawleyit, Magnetit, Mooihoekit, Cubanit, Unnamed (Fe-analogue of Valleriite)
Polierte Sektion von Cubanit-Mooihoekit Erz in reflektiertem Licht. 2 schmale bläuliche Einschlüsse von [Hawleyit] überwachsen skelettartige Kristalle von [Magnetit] (grau) in massive, Sulphid-Erz vermischt mit bronze [Mooihoekit] und wenig hell-grünlichem-gelbem [Cubanit]. Die dunkelgrauen feinkristalline rissfüllende Substanz ist Ferrovalleriit; Oktyabr'skoe (Oktyabr'skoye; Oktyabr'sky) Cu-Ni deposit, Noril'sk, Putoran Plateau, Taimyr Peninsula, Taymyrskiy Autonomous Okrug, Eastern-Siberian Region, Russia
