#DogWalkingGeology from yesterday.... Spud has found some garnet-tastic Moine metabasic tuffs(?) or maybe an intrusion. Each knobbly bit is a large garnet crystal, but alas they are never show external crystal faces, and are always stuffed with gazillions of quartz inclusions. Still, lovely to see! #Metamorphic#Garnet#Mull#Moine#Proterozoic 😊
#quartz inclusions in garnets in metamorphic rocks record structural information that has been obliterated in the rest of the rock. The processes that create snowball #garnet are illuminated by the quartz inclusions! #MinCup23
