…It is an important rock-forming mineral, a general term for a group of minerals that belong to the orthorhombic crystal system and have the chemical composition R 2 SiO 4 (where R is Mg, Fe, Mn, Ca, etc.). The end members are named forsterite (Mg 2 SiO 4 ), fayalite (Fe 2 SiO 4 ), tephroite (Mn 2 SiO 4 ) , and monticellite (CaMgSiO 4 ) . Almost all natural forsterite has a portion (5-40%) of the Mg replaced by Fe, and these are often simply called olivine (forsterite-fayalite solid solution series). … *Some of the terminology explanations that mention "monticellite" are listed below.

…重要な造岩鉱物の一つであり,斜方晶系に属し,化学組成はR2SiO4(ここでRはMg,Fe,Mn,Caなど)で表される一群の鉱物の総称である。端成分はフォルステライトforsterite(苦土カンラン石)Mg2SiO4,フェアライトfayalite(鉄カンラン石)Fe2SiO4,テフロアイトtephroite(テフロ石)Mn2SiO4とモンチセライトmonticellite CaMgSiO4と名付けられている。天然産のもののほとんどすべてはフォルステライトのMgのうちの一部分(5~40%)がFeによって置換されたものであり,それらのものを単にカンラン石(フォルステライト‐フェアライトの固溶体系列)と呼ぶことが多い。… ※「monticellite」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 |
