“…Of the 346 samples, 344 contained <10% mud by volume and were classified on the dual basis of their dominant grain size, using the Udden–Wentworth scale (Udden, ; Wentworth, ), and sorting, as captured by the logarithmical method of Folk & Ward (). To accomplish this textural classification, this study followed Schmitt & Gischler () and initially split the samples on the basis of their dominant grain size (Fig. A) with the result that 54 were revealed to be dominated by very coarse sand (−1 to 0 phi), 140 by coarse sand (0 to 1 phi), 115 by medium sand (1 to 2 phi) and 31 by fine sand (2 to 3 phi).…”

“…Whereas the PRT scheme here was developed by combining two well-established methods for classifying sediments on the basis of grain size and sorting (i.e. Wentworth, 1922 andFolk &Ward, 1957), natural groupings in the prevalence of allochems were used to define DRT classes, as per Gischler & Lomando (2005) and Schmitt & Gischler (2017). Hence, whereas the PRT scheme could be broadly applied, that for DRTs is specific to the present study.…”

“…To guarantee reliable quantitative grain size measurements, a more detailed analysis of the fine material <63 μm was performed by using a laser-optical particle analyser (HORIBA Laser Particle Analyser-950), which runs with 2 g fine material (<63 μm) suspended in 0.4 N Na4P2O7 and demineralized water. The textural classification of the sediment samples follows a modified Dunham (1962) scheme for unconsolidated carbonate sediments (Schmitt and Gischler 2017). Grain size values were calculated for each sample using the textural raw data (Suppl.…”

“…Skeletal debris of Halimeda, coralline red algae, molluscs, foraminifers, corals and echinoderms are the major surface sediment components besides minor constituents of organic and non-skeletal particles (Gischler 1994;Gischler and Lomando 1999;Gischler and Zingeler 2002). Statistical analyses of various reefal carbonate sedimentation sites verified significant differences in marginal reef and lagoon sediment composition (Gischler and Lomando 1999;Schmitt and Gischler 2017). The average composition of the intercalated event beds likely differs in a similar way from those of the varved background sedimentation sections of sinkhole bottom deposits.…”
