Oboniobite is a rare niobium oxide mineral discovered in alkaline pegmatites or carbonatite-related rocks, contributing to the growing list of Nb-bearing accessory phases in these environments. It forms black to dark brownish metallic grains with a submetallic to adamantine luster. The mineral is of scientific interest for characterizing the crystal chemistry of niobium oxides in alkaline and carbonatitic systems.
