摘要

根据对 Kürtün山谷(土耳其北部萨姆松地区)下部一个古石油沉积剖面的矿物学、地球化学和古生物学分析,提供了第四纪晚期的古气候和古环境代用数据。根据 OSL 和放射性碳年代测定法确定了该断面的地质年代。古土壤沉积物断面的基底由 Kürtün 溪的古地台填充物组成,年代为 108 ± 9 ka,相当于末次冰期(MIS5c)。在这个温暖潮湿的时期之后,末次冰期开始了。海平面下降,库尔图恩溪河床加深。冲积阶地沉积物被冲积物覆盖,形成了古土壤序列。古oil 层的最底层带有 68 ± 9 ka 年前(MIS4)干旱气候的痕迹。该地段的中间部分与 MIS2(28959 千卡/公元前)相吻合,其特点是潮湿,同时伴有干旱,并出现了混凝土结核。古oil-沉积剖面的末端是 MIS1(公元前 8381 年)的记录,与更温暖、更潮湿的条件相对应。这项研究强调了库尔图恩河谷下游古石油-混凝土形成对解释 MIS5c 至 MIS1 气候变化的重要性。研究结果与东地中海地区的研究结果一致。建议进行高分辨率多代研究,以更好地了解第四纪晚期当地气候与全球气候现象之间的联系。

Late quaternary palaeoclimates in the lower Kürtün valley (Samsun, Northern Türkiye) through multi-proxy analysis of palaeosoil sediments

Palaeoclimatic and palaeoenvironmental proxy data are presented for the Late Quaternary based on mineralogical, geochemical and palynological analysis of a palaeosoil-sediment section in the lower Kürtün Valley (Samsun region, Northern Türkiye). The geochronology along the section is established based on OSL and radiocarbon dating. The base of the palaeosoil-sediment section consists of a palaeo-terrace fill of the Kürtün Creek dated to 108 ± 9 ka, corresponding to the last interglacial period (MIS5c). After this warm and humid period, the last ice age began. Sea level dropped and the Kürtün Stream deepened its bed. Fluvial terrace deposits were covered with colluvial materials and a palaeosoil sequence formed. The bottommost part of the palaeosoil formation carries the fingerprints of a dry climate of 68 ± 9 ka ago (MIS4). The middle part of the section coincides with MIS2 (28,959 cal BP) and is characterized by humid conditions with arid pulses accompanied by the occurrences of calcrete nodules. The palaeosoil-sediment section ends with the records of MIS1 (8381 cal BP), corresponding to warmer and more humid conditions. This study emphasizes the importance of palaeosoil-calcrete formation in the lower Kürtün Valley for explaining climate changes from MIS5c to MIS1. The results are compatible with studies conducted in the Eastern Mediterranean. High-resolution multi-proxy studies are recommended to better understand the connection between local climates and global climate phenomena in the Late Quaternary.

期刊介绍: The journal is open to papers dealing with the interpretation of ancient and modern biotopes and carbonate depositional environments by means of facies analysis in its broadest sense. Once the central part of research in hydrocarbon exploration, facies analysis more and more integrates modern and ancient biogeological processes of a changing earth. Special emphasis is laid on paleobiology and -ecology, basin evolution, sedimentology including diagenesis and geochemistry, as well as studies emphasising the impact of life on earth history. The main part of the target group will be people in academia.
