Description: | Rock platforms, looking west from near Port a' Chotain, 3.219 km. west of Rhuvaal Lighthouse, north coast of Islay, Argyllshire. The 30 m. pre-glacial rock-platform produced by marine erosion is overlain with gravels of the late-glacial raised beach. In the foreground - the grass-covered platform of the 7.62 m. Postglacial beach. To the right, on the shore, is seen a modern storm beach, of white quartzite shingle. In Late-glacial and Flandrian (Post Glacial) times isostatic recovery sometimes failed to keep pace with eustatic rise in sea level as the water melting from the glaciers returned to the oceans. Consequently, raised beaches and associated marine deposits are now found well above Ordnance Datum. |
