The archaeological site of Sovjan is situated on the edge of the Korçë Basin, southeastern Albania. Its remarkably long and well investigated stratigraphic sequence, spanning from the Neolithic till the Iron Age, makes it an important type- and reference-site for the whole region. At different periods of prehistory it was located on the shores of the former Lake Maliq that once filled the Korçë Basin, but was definitely drained in the 1940′s. These permanent wetland conditions on the site allowed for a high degree of preservation of organic material, especially wood. Based on the current knowledge, level 8 of Sovjan contains the best-preserved wooden material of all the Early Bronze Age sites in the Balkans. Through the combination of dendrochronology and Bayesian modelling, i.e. wiggle-matching, a floating 269-years long tree-ring chronology was constructed, with an absolute end-date range falling between 2158 and 2142 cal BC (2σ). It was possible to establish that the dwellings and the trackway associated with the last occupation phase of level 8 are contemporaneous. Additionally, with the help of the new dendrochronological data and based on previously published charcoal dates, the absolute chronology of the subsequent level 7 is being narrowed-down to a range from the mid-22nd to mid-20th c. cal BC (2σ). The Early Bronze Age layers of the archaeological site of Sovjan, which are particularly pertinent for the 3rd millennium chronology of the southwestern Balkans, can now be dated with high precision for the first time and hence offer a major chronological reference point in the region.

Sovjan(阿尔巴尼亚)的青铜时代早期树木年代学:第24至22 c的第一个树年轮序列。公元前西南巴尔干半岛

Sovjan的考古遗址位于阿尔巴尼亚东南部的Korçë盆地边缘。从新石器时代到铁器时代,它的地层序列非常漫长且经过充分研究,使其成为整个地区的重要类型和参考地点。在史前的不同时期,它坐落在曾经充满科科尔盆地的前马里克湖沿岸,但在1940年代确实被排干了。现场的这些永久性湿地条件可以高度保护有机材料,尤其是木材。根据目前的知识,Sovjan的第8级包含了巴尔干所有早期青铜时代遗址保存最完好的木制材料。通过结合树状年代学和贝叶斯建模(即摆动匹配),2158和2142 cal BC(2σ)。可以确定与8级最后占领阶段相关的住宅和轨道是同时的。此外,借助新的树木年代学数据并基于先前公布的木炭日期,随后的7级绝对年代被缩小到22℃到20℃的范围。校准BC(2σ)。Sovjan考古现场的青铜时代早期层特别与西南巴尔干地区的第三千年年代相关,现在可以首次高精度地定年,因此可以提供该地区的主要年代参考点。
