Yria (western Naxos island, Greece): Sea level changes in Upper Holocene and palaeogeographical reconstruction

Abstract

The Saint Georgios coastal zone, located at the W coast of Naxos, the largest island of the Central Aegean Sea, was investigated in order to determine the palaeo-geography, sea level changes and their effect to the palaeo-environment of western Naxos island and to human activity. Detailed geomorphological mapping, study of micropaleontological and sedimentological characteristics and dating analyses of the Late Holocene of St. Georgios coastal zone were conducted. To obtain information about the Holocene stratigraphy under the recent alluvial cover, three boreholes followed the detailed geomorphological mapping. Microfaunal analysis took place and five samples of plants, shells, peat and charred material were also collected from several layers of the sedimentary sequence and were dated using AMS and conventional radiocarbon techniques providing temporal control of the sediments. The sea-land interactions during Upper Holocene, in relation to the eustatic sea level oscillations, as well as the geomorphologic observations and analysis on deposited sediments, aims to reveal the palaeo-geographic evolution of the landscape and its impact on the archaeological sites. Sea level rise along with sea-land interactions to the landscape evolution and the transgression of sea in 6144 BP have been verified.

Μultiproxy Paleoenvironmental Reconstruction: The Piraeus Coastal Plain Case Study

“…and few Hydrobiidae, revealing a typical lagoonal environment (Nicolaidou et al, 1988;Kevrekidis et al, 1996).Similar assemblages feature meso-ologohaline conditions in several Aegean coastal plains (e.g., Triantaphyllou et al, 2003;Evelpidou et al, 2010;Goiran et al, 2011;Syrides, 2008) and define inner lagoon environment (e.g., Carboni et al, 2010;Koukousioura et al, 2012). The interval from 12 to 11 m core depth (Unit Ab) is featured by the high abundance of A. tepida (generally higher than 70%), accompanied by the presence of Elphidium gunteri and Aubignyna perlucida (up to 20%), a typical species of estuarine and shallow marine environments (e.g., Carboni et al, 2010;Evelpidou et al, 2010). Overall similar foraminiferal assemblages have been characterized as open lagoon environments (e.g., Carboni et al, 2010;Koukousioura et al, 2012).…”

This topic is also well-studied in the Greek islands , and particular attention has been paid to studying sea-level oscillations (Evelpidou et al, 2010;Evelpidou, Vassilopoulos, & Pirazzoli, 2011;Psomiadis, 2011;). However, examination of the mid-to-recent Holocene shoreline evolution of the island of Euboea, the second largest island of Greece ( Figure 1) with an area of ca.…”
