…Silicate minerals are classified into six types based on their crystal structure, and this refers to one of them, and is sometimes called an orthosilicate mineral. In the structure, independent Si-O tetrahedrons (four oxygen atoms occupy the vertices of a tetrahedron, with silicon at the center) are bonded to other SiO 4 tetrahedrons through metal cations other than Si. … *Some of the terminology that mentions "orthosilicate minerals" is listed below.

…ケイ酸塩鉱物はその結晶構造を基にして6種に分類されるが,そのうちの一つをいい,オルトケイ酸塩鉱物と呼ばれることもある。構造の中で独立したSi-Oの正四面体(4個の酸素が正四面体の頂点の位置を占め,その中心にケイ素が存在)は他のSiO4四面体とSi以外の金属陽イオンを媒介として結合している。… ※「オルトケイ酸塩鉱物」について言及している用語解説の一部を掲載しています。 出典|株式会社平凡社世界大百科事典 第2版について | 情報 |
