Abstract

The study area is located in the southern part of the Central Anatolia Neogene Basin (north of Karapınar Town and Acı Göl, Konya). The İnsuyu Limestone Unit, which has a total thickness of 100-400 m, is composed of claystone, sandstone, conglomerate and chert. There are also andezite and pyroclastic interclations within İnsuyu limestone. The claystone layers of this unit are white to pink in color and contain abundant Ostracoda and a few fresh water Gastropoda. In this study, 160 samples from 8 stratigraphic sections were collected but only samples having limestone lithology contained ostracods.Atotal of 16 ostracods taxa (11 previously known and five belonging to open nomenclature) are systematically described as Cyprideis pannonica, C. torosa, Ilyocypris gibba, I. bradyi Candona neglecta, C. candida, C. altoides, C. decimai, Pseudocandona compressa, Heterocypris salina Zonocypris membranea, Ilyocypris sp. Candona sp.1 Candona sp.2, Pseudocandona sp. and Cypridopsis sp. Based on this Ostracoda fauna, the age of this unit is assigned as Pliocene-Early Pleistocene. This fauna indicates a few brackish but dominantly fresh water conditions in a lacustrine environment.

Özet

Çalışma alanı “Orta Anadolu Neojen Baseni” nin güney kesiminde yer almaktadır (Karapınar Kasabası kuzeyi ve Acı göl, Konya). İnsuyu Kireçtaşı birimi 100-400 m toplam kalınlığa sahip olup, kiltaşı, kumtaşı, konglomera ve çört tabakalrından oluşmaktadır. İnsuyu Kireçtaşı biriminde andezitler ve piroklastik seviyeleri de vardır. Kiltaşları beyaz ve pembe renklerde olup bol miktarda ostrakod ve daha az oranda tatlı su gastrapod fosilleri içermektedir. Bu çalışmada, 8 stratigrafik kesit ölçülmüş ve bu kesitlerden 160 örnek toplanmıştır. Ancak sadece kireçtaşları ostrakod fosili içermektedir. Sonuç olarak, toplam 16 ostrakod taksonu (11 bilinen ve 5 isimlendirmeye açık) ayırtlanmıştır. Bunlar: Cyprideis pannonica, C. torosa, Ilyocypris gibba, I. bradyi, Candona neglecta, C. candida, C. altoides, C. decimai, Pseudocandona compressa, Heterocypris salina, Zonocypris membranea, Ilyocypris sp.Candona sp.1 Candona sp.2, Pseudocandona sp. and Cypridopsis sp. taksonlarıdır. Ostrakod topluluğuna göre birimin yaşı Pliyosen-Erken Pleyistosen olarak belirlenmiştir. Bu fauna topluluğu tatlı su (laküstrin) ortamına özgüdür.
