摘要

摘要在波兰中部Koło盆地的Koßmin遗址发现了晚魏氏时代的松（Pinus sylvestris L.）的亚化石树干（Dzieduszyńska et al.，2014a）。另一部分带树干的有机沉积物是在研究项目的框架内挖掘出来的。共对来自科罗兹明的224个样本进行了树木年代分析；它们通常代表40至70年树龄的幼树。根据最收敛的序列，产生了长达210年的2KOL_A1年表。使用摆动匹配方法，其年代为约13065–12855 cal BP。对埋藏在有机沉积物中的树干进行树木年代测定，其中大多数发生在原位，表明树木死亡连续发生，超过100年。这可能是由于不利的气候条件以及强风等极端事件造成的。

A Tree-Ring chronology from Allerød–YD transition from Koźmin (Central Poland)

Abstract Subfossil trunks of pine (Pinus sylvestris L.) from the Late Weichselian were discovered in the site Koźmin in the Koło Basin, central Poland (Dzieduszyńska et al., 2014a). Another part of organic sediments with trunks was excavated in the frame of the research project. Altogether 224 samples from Koźmin were analysed dendrochronologically; they represented generally young trees, 40 to 70 years old. Based on the most convergent sequences, the chronology 2KOL_A1 was produced, 210 years in length. With the wiggle-matching method, it was dated to ca. 13065–12855 cal BP. Dendrochronological dating of trunks buried in organic sediments, most of which occurred in situ, revealed that tree deaths occurred successively, over more than 100 years. That could have been due to unfavourable climatic conditions, as well as extreme events, e.g. strong winds.

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.
