30 Marine tidal notch is a geomorphological formation which develops around mean sea level in the limestone shorelines due to
biological erosion and/or wave action (PIRAZZOLI 1986). It generally has a half-ellipsoidal shape and its height corresponds to
intertidal zone. This formation that develops during sea level stability is a precise sea level marker, and its presence above or below
modern sea level indicates more or less rapid tectonic uplift or subsidence.
