Wave erosion has exposed a cross section through bedded scoria units of the Cape Mavrorachidi scoria cone on the SW side of Thera Island. Behind the cone to the left are exposures of light-colored rhyodacitic tuffs of the Akrotiri Peninsula. A 451,000 ± 27,000 BP (before present) Argon-Argon date was obtained from a lava flow from the Cape Mavrorachidi cone.
