コエサイト超高圧環境を物語る二酸化ケイ素の多形

コエサイト二酸化ケイ素超高圧変成作用石英
Eclogite from Norway with a garnet (red) and omphacite (greyish-green) groundmass. The sky-blue crystals are kyanite. Minor white quartz is present, presumably from the recrystallization of coesite. A few gold-white phengite patches can be seen at the top. A 23 millimetres (0.91 in) coin added for scale.
