Description :
Numerous examples all along the Mediterranean coastline show that beach-rock frequently originates inside soft fossil holocene marine deposits and is exposed only when the coast recedes. The present beach often hides it during the summer, thus making it possible for a veil of sand to cement itself unconformably on the slabs of beach-rock. The phenomenon of receding coastlines being general in the Mediterranean, it is quite natural that beach-rock forms in this ancient sedimentary stock, especially since the cementation process requires immobilization of the constitutive materials. Thus, as the coastline recedes, new slabs built up behind pre-existing ones.
