earthstory:devilmeadow:Found on the beach at Porthallow, Cornwall. This beach is geologically quite unique as it is on the Lizard plate boundary, so ancient mantle rocks from deep down are exposed at the surface. Not sure what this is (possibly Glaucophane or some kind of blueschist?) but it looks damn prettyNow this is a pretty rock. Based on the description I’m guessing it is “Lizardite” - actually named for this site - a type of serpentine mineral formed when mantle rocks are altered by water. -- source link
