cubin
Cubin is a rare mineral belonging to the perovskite group, with the chemical formula Cu3N. It was first discovered in 1997 in the Khibina alkaline massif in the Kola Peninsula, Russia. The mineral is named after its copper (Cu) and nitrogen (N) composition. Cubin is characterized by its cubic crystal structure, which is a unique feature among minerals. It typically forms as small, dark blue to black crystals or as inclusions in other minerals. The mineral is notable for its high nitrogen content, making it an interesting subject for study in the fields of mineralogy and geochemistry. Cubin's rarity and unique properties make it a valuable specimen for collectors and researchers alike. Despite its limited occurrence, cubin continues to be a topic of interest in the scientific community due to its unusual composition and crystal structure.
