SON BUZUL MAKSİMUM (LGM)-GEÇ HOLOSEN EREGLI HAVZASININ PALEOÇEVRESEL EVRİMİ: JEOLOJİK İNDİKATÖRLER YARDIMIYLA İLK SONUÇLAR
Öz
Ereğli’nin
doğusunda, Adabağ bataklığı ile Zanopa alüvyon yelpaze ve Adabağ Geç Pleistosen
geçidi arasında yer alan KAR isimli profil 420 cm derinliğe erişen bir karot olup,
yaz 2016-2018 yılları arasında örneklenmiştir. Bu karotlar yörede yapılan diğer
iki yaşlandırılmayan seriler ile ilişkilendirilmiştir: Adabağ bataklığının doğu
kısmında BAĞ yer alır ve KAR kesiti ise Zanopa alüvyon yelpazesinin kuzeyinde
Kargacık köyüne yakın bir yerdir. KAR (bu çalışmanın konusu) kayıtları Konya
ovasında Mezolitik ve Neolitik dönem insan yaşamının çevresi üzerine bilgiler
vermektedir. Bu çevresel evrimin rekonstrüksiyonu sediman içeresinde bulunan
tane boyu, karbonat, organik madde ve mineral bileşenlerine dayanmaktadır. Bu
çalışma sonucu, elde edilen karotlar üzerinde jeolojik çalışmaları yardımıyla Niğde
Ömer Halisdemir Üniversitesinde tamamlanması amaçlanmıştır. Bu veriler son 25
bin yıldan beri son buzul maksimum (LGM) İç Anadolu’da meydana gelen iklim ve
çevresel değişikliklerini ortaya çıkarmaya yarayacaktır. Kayıtlar sırasıyla:
(1) tane boyu dağılımı analizi, istatiksel değerlendirme sonuçları ile (2)
mineral içeriği (kil türleri, diğer mineraller) XRD analizleri sonucu; (3) ince
kesit çalışmaları sonucu mikro yapının ortaya çıkarılması; (4) sedimanların
jeokimyasal içerikleri şeklindedir.

FROM POST-LGM TO HOLOCENE EVOLUTION OF ENVIRONMENTS IN THE EREĞLI BASIN: FIRST RESULTS FROM GEOLOGICAL INDICATORS
Öz
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.
