Glacial Sediments. Templetown Beach, Cooley.3D Model
Coords: 53.9816 -6.1439
A Coastal cliff composed of sediments exposed above the present day beach due to ‘Isostatic Rebound’. As ice sheets melted at the end of the last glaciation land has risen with respect to sea level.
The huge weight of ice that pressed the crust down into the mantle during the glaciation was removed as the ice melted allowing the land to ‘rebound’ and uplift along the coast. Sediments that make up the cliff have been exposed due to coastal erosion.
We see the evidence for uplift in the form of sediment layers in the cliff and the presence of ‘Raised Beaches’ at the top of the cliff. A flat cliff top forms a horizontal line extending along this part of the coast and inland for some distance and represents an ancient beach now raised c10m above current sea level.
