Subfossil trunks of oak (Quercus robur L. and Q. petraea Lieb.) are fundamental
for construction of long dendrochronological standards for southern
Poland. In the last three years over 400 new oak trunks from alluvial
deposits from the basins of the rivers Vistula and Odra were analysed.
Most trunks came from the last 2500 years and the produced local
chronologies permitted for improvement of the standard chronology
POLAND2, covering the period 474 BC – 1555 AD.
Subfossil oak trunks from several sites in the river
Vistula basin (Grabie, Wolica, Podolsze and others) and from alluvia of
the river Odra in Wrocław enabled construction of a new long chronology
C_3000E, spanning the years 1795-612 BC. This chronology was absolutely
dated through teleconnection with standards for southern Germany. A row
of floating chronologies, dated with the radiocarbon method, was
established for the older periods of Holocene. They cover the following
intervals: ca. 670–400 BC, ca.
2200-1900 BC, ca. 3400-3100 BC, ca.
3800-3600 BC and ca. 6650-6150 BC. Subfossil oak
chronologies constructed by the author, together with standards based
on living trees, monuments of wooden architecture, and archaeological
timbers from Wielkopolska (448-1994 AD), Lower Silesia (780-1994 AD)
and Małopolska (910-1997 AD) practically allow for absolute dating of
oak timbers from the area of southern Poland coming from the last 4000
