Fanguangite is a rare niobium titanate oxide mineral first described from granitic pegmatites in China, belonging to the columbite-tantalite family. It forms black to dark brown prismatic crystals with a submetallic luster and is typically found in rare-element pegmatites enriched in niobium. The mineral is scientifically important for understanding Nb-Ti oxide crystal chemistry in evolved pegmatitic systems.
