Radiocarbon Fluctuations During the Third Millennium BC

Abstract
Precision14C analyses have been performed on samples comprising 1 to 4 annual rings from the south-central European dendrochronologic sequence of sub-fossil oak wood covering the period 1930 to 3100 bc. Apart from a major deviation in the 29th century bc, the14C fluctuations have amplitudes of ca 10‰ and a possible periodicity of 90 years. A14C peak at 2190 bc has a rise- and decay-time of 14C. The14C calibration curve derived from these data can be used for precise dating of the Early Bronze Age in the Near East.
