Recently, an olive branch constitute buried nether stone fragments at Santorini was used to appointment the erruption to betwixt 1627 as well as 1600 BCE, to a greater extent than than a century before than the 1500 BCE appointment suggested yesteryear archaeologists.The dating was based on the supposition that the outermost band of forest was formed only before the branch was buried hold upwards yesteryear the eruption.
To assess whether an olive tree’s outermost band is produced only prior to the tree’s decease as well as tin thus hold upwards used for reliable dating, Elizabetta Boaretto as well as colleagues analyzed the radiocarbon concentrations inwards xx samples taken from a modern olive tree body as well as eleven samples taken from a living branch cutting inwards 2013.
They constitute that inwards both cases private samples, all of which were taken from the layer of forest nearest the bark, could vary inwards appointment yesteryear equally much equally forty to l years.
The findings challenge the interpretation of the results obtained from dating the olive branch constitute at Santorini, which may hold upwards pregnant non entirely for the archaeological history of the Aegean, Arab Republic of Egypt as well as the Levant but equally good for whatsoever futurity studies based on archaeologically preserved olive wood.
