WebEclogite GR 30c is a massive medium-grained rock, consisting of garnet, omphacite, glaucophane, epidote, phengite, apatite, quartz, and rutile. Garnet poikiloblasts occur as euhedral crystals, rich in inclusions such as titanite, epidote, apatite, and quartz. The foliation is defined by glaucophane and epidote.
