Abstract

Abstract This study presents the sedimentological and pollen analysis, and radiocarbon dating of the palaeochannel fill deposits situated on the wide alluvial ridge on which 131 archaeological sites were discovered. The analyzed territory covers the right bank of the San river valley (in the area of the Leszno profile) with an area of 72.5 km2. Increase of fine-grain sand sediments, and the presence of redeposited fragments of clayey silts (soil aggregates) correlates well with the increase man’s activity in the 2nd and the 1st half of the 1 st millennia BC (the decline of the Mierzanowice culture, the Trzciniec culture, the Tarnobrzeg Lusatian culture) as well as in the 1st millennium AD (the Przeworsk culture and the early Medieval settlement) and with transformation of plant communities recorded in the palynological sequence. The layer of sediments at the depth of 85–69 cm with the highest proportion of the finest clay fraction may indicate the reduction of cultivation or abandonment of arable land (the pre-Roman (La Tène) period).

波兰东南部桑多米日盆地圣河牛轭湖沉积物史前人类住区的时间变化

摘要本文对位于宽冲积脊上的古河道填充物进行了沉积学、花粉学分析和放射性碳定年，并在此发现了131处考古遗址。所分析的区域覆盖了San river河谷的右岸(在Leszno剖面区域)，面积为72.5 km2。细粒砂沉积物的增加和粘土粉砂(土壤团聚体)再沉积碎片的存在与公元前1千年下半叶和上半叶人类活动的增加(Mierzanowice文化、Trzciniec文化、Tarnobrzeg Lusatian文化的衰落)以及公元1千年(Przeworsk文化和中世纪早期定居)以及孢粉序列中记录的植物群落的转变密切相关。在85 ~ 69 cm深度的沉积物层中，最细粘土组分的比例最高，这可能表明前罗马(La t)时期耕地的减少或放弃。

期刊介绍： Geochronometria is aimed at integrating scientists developing different methods of absolute chronology and using them in different fields of earth and other natural sciences and archaeology. The methods in use are e.g. radiocarbon, stable isotopes, isotopes of natural decay series, optically stimulated luminescence, thermoluminescence, EPR/ESR, dendrochronology, varve chronology. The journal publishes papers that are devoted to developing the dating methods as well as studies concentrating on their applications in geology, palaeoclimatology, palaeobiology, palaeohydrology, geocgraphy and archaeology etc.
