veemudelite
Veemudelite is a rare mineral discovered in 2019, found in the Khibina alkaline complex in Kola Peninsula, Russia. It is named after Veemude, a village near the discovery site, and "delite" refers to its delafossite structure. Veemudelite is a copper-iron oxide with the chemical formula Cu2FeO3. It crystallizes in the trigonal system and typically forms as dark brown to black, prismatic crystals. The mineral is notable for its unique structure and composition, which make it a subject of interest for mineralogists and geologists studying the complex geochemical processes in alkaline igneous rocks. Veemudelite's discovery has contributed to the understanding of mineral diversity and the geological history of the Khibina complex.
