Özet: Among 2016-2018, three cores were retrieved from marshy areas in the Ereğli plain at one locations positioned in the outer rim of the Upper Pleistocene alluvial fan of the Zanopa river (Konya Province). The first one (KAR) are from the Adabağ marsh which has developed in the shadow of a tombolo sand bar pertaining to the LGM Konya Paleolake system. This bar is dated LGM or Late Glacial. This one cores delivered complementary sequences representing two distinct part of the marsh today: (a) ADA is from a dry part of the marsh close to the sand bar; (b) BAG is from a still wet part of the marsh close to the border of the Zanopa alluvial fan. The third core (subject of this study: KAR) was taken from a peaty area expanding over the northern part of the alluvial fan, which is nowadays dry and on destruction. The communication aims at presenting initial results of geological analyses performed on these cores at Niğde Ömer Halisdemir University. These will contribute to reconstructing the climatic and environmental evolution in Ereğli area since 25 ka (LGM). Proxies presented in the communication are: (1) grain size distribution analyses, with statistic treatments of the results; (2) mineral (silt, clay) composition using XRD analyses; (3) sediment structure using thin sections; (4) geochemical content of the sediments.
