Description :
Beach rocks are beach materials lithified above high tide level. The beach material will be cemented under the prevailing conditions of Mediterranean climate there. Before being cemented beach materials must have been wetted, and this process is linked to rare oceanographic-climatic conditions, such as wind-tides lifting up the sea level and extending the swash zone landward. Under even these conditions beach rocks are destroyed by backswash and breakers, too. Formation and destruction of beach rock occur at the same time. Periods of months, years or 10 years are required for beach rock formation, whereas beach rocks may be destroyed in periods of 10-10 years. The authors working on beach rock up to now agree beach rock to be an excellent indicator of sea level fluctuations, especially of Holocene fluctuations.
