A representative alkali amphibole mineral. Its chemical composition is Na2(Mg,Fe2+)3Al2Si8O22 ( OH ) 2 . Mg and Fe can be mixed freely. Amphibole with a high Fe content is called ferroglaucophane. Al can be continuously substituted for Fe3 + , but amphibole with intermediate composition is called crossite (also called blue amphibole), and amphibole with a high Fe3 + content is called riebeckite (also called sodalite).

アルカリ角セン石の代表的な鉱物。化学組成はNa2(Mg,Fe2+)3Al2Si8O22(OH)2で表される。MgとFeは任意に混ざりあう。Feの多いものは鉄ランセン石ferroglaucophaneと呼ばれる。Alは連続的にFe3+と置換することができるが,中間的な組成の角セン石はクロス(角)セン石crossite(青セン石ともいう),Fe3+が多い場合はリーベック(角)セン石riebeckite(曹セン石ともいう)と区別して呼ばれる。
