Imaggeo on Mondays: Cooking crystals in the Earth cauldron

This picture shows a 30 micrometer thick rock section of a gabbro from the Rum Layered Intrusion (Scotland). Large clinopyroxene crystals are enclosed in a foliated fine grained groundmass of plagioclase and olivine. The clinopyroxene core crystallized at an early stage, at 1160°C.
