Fig. 7From: Shoreline evolution and modern beach sand composition along a coastal stretch of the Tyrrhenian Sea, southern ItalyDiagram showing the relative abundance of single crystals versus composite rock fragments (both phaneritic rock fragments and aphanitic lithics) in shoreface and backshore samples. The shoreface samples are ordered by depth (from the − 5 m isobath to the − 20 m isobath), whereas the backshore samples are grouped from north to south along the studied coastal stretch (from Capo Suvero to Gizzeria Lido). The sample numbers/names are shown on the x-axis; the contents (expressed in %) of single crystals (SC) and rock fragments (RF) are shown on the y-axisBack to article page
