Beachrocks in particular have&amp;nbsp;received various arguments concerning their use as reliable sea level indicators and&amp;nbsp;their formation environment. This work focuses on the coasts of East Attica in order to&amp;nbsp;trace the palaeoshorelines of the Upper Holocene through the study of beachrocks. The&amp;nbsp;coastal zone was surveyed in detail by snorkelling and diving, in order to locate, map&amp;nbsp;and sample beachrocks. The samples were studied under a SEM, which showed that the&amp;nbsp;beachrocks are mainly composed of quartz grains, a few calcites and feldspars, while&amp;nbsp;the carbonate cement is characterized with the presence of MgO at percentages between&amp;nbsp;5 and 7.8%. Based on correlations with published drillings in the study area, the studied&amp;nbsp;beachrocks should not be older than 2000 years BP.&lt;/div&gt;</style></abstract></record></records></xml>
