Datarea radiocarbon a unor probe de lemn şi derivaţi din lemn, ca urmare a unor tratamente termice. Un punct de vedere arheometric asupra unor eşantioane de la Mǎguricea Branului

Abstract

Radiocarbon dating by AMS accelerated ion mass spectrometry method, used from 2012 at IFIN-HH-Măgurele, offered recently the scientific frame for an interdisciplinary approach, from archaeologic and archaeometric perspectives, applied to wood samples. The first AMS results, issued in 2021 on six samples from Măguricea Branului archaeological site, have suggested a chronology around the 13th century AD, the differences being explained on terms detailed in this paper. The latter four samples, collected in the next archaeological campaign, gave very different dates. The difficulties experienced with these four samples driven us to develop new lab treatment, aiming carbonization of wood. Even so, the samples from 2022 could not be dated in a helpful manner, with parameters as terminus post quem, time-width, apparent ages. The paper could be of interest to archaeologists taking wood samples for AMS dating.
