#ThinSectionThursday Perhaps my favourite rock 😍 Sample U5A17 from my PhD fieldwork collected from Unit 5 of the Eastern Layered Intrusion in Rum a long time ago. Blue and green crystals of olivine enclosed in buff-coloured clinopyroxene, and striped plagioclase. Cross-polars illumination. Field of view 2mm across. #Microscopy #IsleOfRum #Geology #Igenous
