Vanadate mineral - vanadate mineral

Japanese: バナジン酸塩鉱物 - バナジンさんえんこうぶつ(英語表記)vanadate mineral
Vanadate mineral - vanadate mineral
A general term for minerals with the basic chemical composition of vanadate V 2 O 5n H 2 O. They are closely related to phosphate minerals and arsenate minerals, and phosphorus and arsenic may replace some of the vanadium atoms in the crystal structure. Many of them have vivid colors such as yellow, orange, yellow-green, and brown. A representative example is vanadinite Pb 5 (VO 4 ) 3 Cl. Important resources of vanadium and uranium include carnotite K 2 (UO 2 ) 2 (VO 4 ) 2 ・3H 2 O and tyuyamunite Ca(UO 2 ) 2 (VO 4 ) 2 ・5-8H 2 O, which are the main minerals in sandstone-type uranium deposits on the Colorado Plateau in the United States.
