Rock 366 : Day 212 : Caerbwdy Sandstone

Rock3660818

Day 212 : The Lower Cambrian Caerbwdy Sandstone Formation. Like the underlying Caerfai Shales of Day 202, for a marine rock they are unusually red, probably indicating something weird about the geochemistry of the Early Cambrian Iaepetus Ocean.  From Caerfai Bay, Pembrokeshire, Wales.
