noun
uraninite
A uranium-rich mineral, also known as pitchblende when massive. Technical term used in geology and mineralogy.
閃ウラン鉱は重要なウラン鉱石である。
Uraninite is an important uranium ore.
Full katakana variant; less common but used in some technical contexts.
Compound of 閃 (sen, 'flash' or 'glitter', referring to its luster) + ウラン (uran, 'uranium') + 鉱 (kō, 'ore'). The exact derivation is uncertain, but the name likely reflects the mineral's shiny appearance and uranium content.
