摘      要：Clastic sedimentary features of beachrocks and unconsolidated deposits of parent beaches were investigated along the northern Aegean coastline(Greece) to assess their suitability in palaeo-environmental *** paired datasets were collected in the Thermaikos,Toroneos,Siggitikos and lerissos gulfs of the Chalkidiki Peninsula,the adjoining Kavala Gulf and Thassos Island,comprising beachrock cores and companion beach subsurface *** size analyses based on univariate and bivariate statistics suggest that,during the time period of beachrock formation,depositional conditions differed distinctly from those of the modern parent *** results imply difference of maturity level of beach evolution from the time of cementation(coarser materials-early stage of beach formation) to modern situation(finer materials-reworked and ’mature’ beach sediments).Furthermore,the findings indicate increasing coastal protection due to beachrock exposure in the modern swash *** conclusion,it is suggested that textural analysis of beachrocks in comparison with unconsolidated sediments of the parent beach might provide information regarding differences of coastal depositional regimes and future research could focus on specific-layer analysis and comparison.
