Abstract

This study investigated the calcareous nannofossil assemblages in detail from the early Miocene aged Lice Formation outcropping in the Kahramanmaraş basin. The biostratigraphy of calcareous nannofossils was outlined and paleoenvironmental features determined. In 81 samples taken from three measured sections in the region, 17 calcareous nannofossil genus and 48 nannofossil species were identified. These calcareous nannofossil genus and species identified the Lice Formation as being in the CNM4 nannofossil biozone. The abundance and diversity of early Miocene calcareous nannofossil species varied in the measured sections, with the samples generally moderate-poor, apart from a few samples. The relative abundance of individuals of Cyclicargolithus floridanus, Coccolithus pelagicus, Reticulofenestra hagii and Sphenolithus moriformis species, with paleoecological importance identified in the study region, indicate that in early Miocene times, the basin in which the Lice Formation deposited was meso-eutrophic with excess nutrient input, temperate and generally stable shallow marine conditions.

东地中海土耳其卡赫拉曼马拉什盆地早中新世虱子地层的钙质化石组合变化与古环境解读
本研究详细调查了卡赫拉曼马拉什盆地早中新世时期出露的虱子地层中的钙质化石群。研究人员概述了钙质化石的生物地层学,并确定了古环境特征。在该地区三个测量断面采集的 81 个样本中,确定了 17 个钙质化石属和 48 个化石种。这些钙质化石属种确定了虱子地层属于 CNM4 纳化石生物区。早中新世钙质化石物种的丰度和多样性在测量断面上各不相同,除少数样本外,一般为中度贫乏。在研究区域发现的具有重要古生态学意义的 Cyclicargolithus floridanus、Coccolithus pelagicus、Reticulofenestra hagii 和 Sphenolithus moriformis 物种的个体相对丰度表明,在早中新世时期,虱子地层沉积的盆地是中富营养化的,营养物质输入过多,温带和浅海条件基本稳定。
