Abstract

Abstract Results of geological and pollen investigations of the lake-bog sediments from the section Wietrzychowice W5, located nearby the Neolithic Funnel Beaker Culture (FBC) megaliths, are presented. The pollen data reveal that sedimentation at Wietrzychowice has begun at the beginning of the Holocene (Preboreal). Pollen analysis was used to determine stratigraphy with regard to sediment characteristics. The pollen spectrum was divided into 8 LPAZes (1-7Xa, 7Xb) which were also, where possible, stratigraphically classified. Radiocarbon dating of 6 730 ± 90 BP (5 730–5 480 BC, MKL-702) at depth of 1.20 m confirmed the pollen analysis age estimation. Five settlement episodes were found in organic sediments in the upper part of the W5 core. The first was presumably during the Preboreal, the second in the early Atlantic, the third in the late Atlantic (probably Neolithic FBC), the fourth in the early Middle Ages and the last one in the late Middle Ages. The pollen analysis was useful to point irregularities in sediment succession. Such a situation made palaeoenvironmental interpretation difficult, but further research is still needed to enable an accurate reconstruction.

波兰中部Kujawy东南部wietrzychoice地区花粉记录揭示的全新世湖泊-沼泽沉积物序列扰动

摘要介绍了位于新石器时代漏斗烧杯文化(FBC)巨石附近的wietrzychoice W5剖面湖泊-沼泽沉积物的地质和花粉调查结果。花粉资料显示，wietrzychoice的沉积作用始于全新世(前寒武纪)初期。用花粉分析确定沉积物特征的地层学。花粉谱分为8个lpaz (1-7Xa, 7Xb)，并在可能的情况下进行了地层划分。1.20 m深度6 730±90 BP (5 730 ~ 5 480 BC, MKL-702)放射性碳定年证实了花粉分析的年龄估计。W5岩心上部有机沉积物有5个沉降期。第一次大概是在前北方时期，第二次是在大西洋早期，第三次是在大西洋晚期(可能是新石器时代)，第四次是在中世纪早期，最后一次是在中世纪晚期。花粉分析有助于指出沉积物演替中的不规则性。这种情况使古环境解释变得困难，但仍需要进一步的研究来实现准确的重建。

期刊介绍： Studia Quaternaria is designed to publish scientific works concerning the Quaternary, on local, regional and global scale. Studia Quaternaria is interested in all fields of research dealing with stratigraphy and reconstruction of the past environments, including palaeogeography, palaeoecology, palaeoclimatology, palaeohydrology etc. The journal is also open to studies of natural environmental processes, and to recognition of mechanisms involved in the dynamics of our environment. The clue is that the Quaternary is still ongoing and vivid, and understanding of its past and present development support each other.
