Reconstruction of Mid-Holocene sedimentary environments in the central part of the Thessaloniki Plain (Greece), based on microfaunal identification, magnetic susceptibility and grain-size analyses

Magnetic mineralogy and its implication of contemporary coastal sediments from South China

“…Magnetic properties of marine sediments can often contribute reliable information on environmental change (Kumar et al 2005;Sangode et al 2007;Yang et al 2008;Alagarsamy 2009;Zheng et al 2010) and magnetic parameters such as magnetic susceptibility (MS) became a kind of basic data for marine sediment research (Evans and Heller 2003;Yim et al 2004;Ghilardi et al 2008;Meena et al 2011). As a fast and cost-effective parameter, MS also has been successfully used as a proxy for the detection of anthropogenic pollution caused by metallurgical dusts, fly ashes from power plants and urban airborne particulates (Bityukova et al 1999;Jordanova et al 2003;Gautam et al 2004;Lu et al 2007).…”

Μultiproxy Paleoenvironmental Reconstruction: The Piraeus Coastal Plain Case Study

“…Within Unit A, the occurrence of diverse dinoflagellate cysts and foraminifera linnings ( Figure 3) is the palynological evidence of the marine influence on the deposits (Kouli et al, 2009). In addition, Pseudoschizaea and type 207 are indicators of soil erosion and increased riverine runoff (Figure 3), which together with the high values of magnetic susceptibility (mean ~40 x10 -8 m 3 /kg) between 12 m depth and the bottom of the core, imply increased fresh water input in the depositional environment, thus supporting the closed lagoon paleoenvironmental conditions (Ghilardi et al, 2008;Liu et al, 2012). The lower values of magnetic susceptibility within Unit Ab (12-9.5 m core depth) in respect to Unit Aa, point to higher marine influence associated with open lagoon paleoenvironmental conditions.…”

“…All iron-bearing minerals are sensitive to a range of environmental processes, which makes magnetic measurements extremely useful for detecting signals associated with environmental processes (Liu et al, 2012). In particular, magnetic susceptibility measurements can be used as a rapid, simple and non-destructive proxy to indicate magnetic changes in the sediments corresponding to different depositional environments (Oldfield and Yu, 1994;Verosub and Roberts 1995;Dearing, 2000;Ghilardi et al, 2008;Yang et al, 2008;Wang et al, 2009). …”

Zarys środowisk sedymentacyjnych w dolinie Anthemousa (północna Grecja). Wstępne wyniki badań geoarcheologicznych w ramach projektu Anthemous Valley Archaeological Project

“…Zmiana linii brzegowej na obecną chwilę pozostaje nierozwiązana, niemniej nie sposób wykluczyć jej możliwych fluktuacji, w świetle badań Równiny Salonickiej, w niedalekim sąsiedztwie (Ghilardi et al 2008). Odwierty wykonane w 2016 r. dostarczyły materiału, który będzie badany pod tym właśnie kątem.…”
