Glaucophane lawsonite epidote
A metamorphic rock of roughly basaltic composition, defined by the presence of glaucophane with lawsonite or epidote. Other minerals that may be present include jadeite, albite, chlorite, garnet, and muscovite (phengitic white mica). Typically fine-grained, dark colored. Category for rocks commonly referred to as blueschist.
Fabric is weakly developed in this rock in many cases, so the fabric categories 'foliated metamorphic rock, 'schist' or 'granofels' may apply.
