The Oak Chronology (948-1314 AD) for the Zary Area (Sw Poland)

The study presents the results of investigations aimed at construction of a site chronology for oak wood from the surroundings of Zary (SW Poland). The 366-year chronology ZY_2006, covering the period 948-1314 AD was determined on the basis of 189 individual ring patterns representing samples of archaeological wooden objects lifted at the excavation works led in the Old Town of Zary in the years 2004-2005. The chronology produced exhibits high similarity to the standards for the neighbouring regions: Wielkopolska and Lower Silesia. The statistical parameters of the chronology are very high and, thanks to the signature years determined, it should be an excellent tool for dating samples of mediaeval timbers from the whole region of Ziemia Lubuska, including some with relatively short dendrochronological sequences.
