Quaternary Evolutionary Stages of Selinitsa Cave (SW Peloponnese, Greece) Reveal Sea-Level Changes Based on 3D Scanning, Geomorphological, Biological, and Sedimentological Indicators

Significant evolutionary stages of Selinitsa Cave (SW Peloponnese, Greece) were revealed by 3D mapping, as well geomorphological study the cave and nearby landscape. Four marine terraces identified in area coastal at 6, 10.7, 16.6, 30–32 m above sea level (asl), with terrace 16.6 representing Marine Isotope Stage (MIS) 5. The widest karstified space clusters between 15.73 18.05 peak lying 16.4 asl, corresponding to where phreatic/epiphreatic zone was stable for a sufficient period time. A tidal notch asl entrance is correlated m. Both features correspond sea-level stand which intense karstification occurred. bears horizontal arrangement Lithophaga borings vertex. Sedimentological investigation fine-grained deposit paleohydrologic regime cave. It characterized “slack-water” facies, indicating very low water flow speeds, whereas thickness points hydrological conditions prolonged periods. sediment height 18.8 indicates flooding higher than level. overlying Plattenkalk flysch most probably major source detritus, predominance authigenic dolomite (>98% modal carbonate fraction) hyposaline environment related mixing percolating fresh water. approach this shows significance bio-geo-Relative Sea Level (RSL) indicators, sedimentology deciphering paleogeographic evolution karstic systems subsequently defining paleoclimate areas Greece eastern Mediterranean during Late Quaternary.
