Description :
The radiocarbon dating of a beach-rock from the Ligurian coast (Italy) has given an apparent 14 C age of 3330 95 yr B.P. In spite of the uncertainty on the actual age, the beach-rock seems to have been developing even after the Post-glacial climatic optimum. Nine horary pH measurements have been done donc during 26 hours in 4 solution pits developed on the emerged beach-rock. High variations are observed. These observations are the same for each pit and this corroborates the importance of biochemical processes like photosynthesis and respiration on the pH control in the solution pits.
