The eclogites have a restricted bulk chemical composition corresponding to gabbroic-basaltic rocks and consist primarily of two mineral phases: a grass-green clinopyroxene called omphacite, and a red or red-brown garnet. Due to the restricted range of eclogite compositions, the only parageneses are omphacite + garnet with kyanite or with orthorhombic pyroxene.
