A mineral that contains barium as its main chemical component. It occurs as special hydroxide minerals, salt minerals such as carbonates and sulfates, and silicate minerals. Minerals other than silicates are formed by hydrothermal action and hot spring action. As a hydroxide mineral, it is contained in romanechite BaMn 2+ Mn 4+ 8 O 16 (OH) 4. In addition, witherite BaCO 3 as a carbonate and barite BaSO 4 as a sulfate are known, and are important raw materials for barium. Source: Heibonsha World Encyclopedia, 2nd Edition Information |
バリウムを主要化学成分として含有する鉱物。特殊な水酸化鉱物,炭酸塩,硫酸塩などの塩類鉱物およびケイ酸塩鉱物として産出する。ケイ酸塩鉱物以外は熱水作用,温泉作用などにより生成する。水酸化鉱物としては,硬マンガン鉱romanechite BaMn2+Mn4+8O16(OH)4に含有される。さらに炭酸塩としての毒重石witherite BaCO3,硫酸塩としての重晶石barite BaSO4などが知られ,バリウムの原料鉱物として重要である。
