A sea stack on the west coast of Orkney showcases Devonian sedimentary strata and implies terrific storm waves in its geomorphology.
Any readers have any idea what this strange rock is? It’s got wild patterns! These samples were in the garden of a local rockhound in Lerwick; I have zero idea what the mineralogy is; I was just stunned by the “scale-like” pattern of gray and pink. I’d be eager to hear your ideas what this might be. Thanks very much in advance!
