Age structure of the Australian lungfish (Neoceratodus

The outcome of this speculative analysis is that, based on radiocarbon evidence, Thera could be related to any one of the five volcanoes that have left evidence in ice core and tree ring records between 1650 B. C. and 1595 B. C. With the exception of the GISP2 1623 B.C. layer, none of the others have been searched for tephra from Thera.

6/1/2016 · It is possible that cool mixed forest steppe dominance was appeared during the Upper Palaeolithic and cool mixed forest dominance was formed in the Epipalaeolithic. The radiocarbon ages cannot show the change of these horizons but it is possible that the process passed off during 13,000 cal BP (11,000 cal BC) years similarly to other data [82, 83].

The preparation of ice samples follows the procedure according to Jenk et al. (2007). First, samples are decontaminated in a cold room (-20 ∘ C) by removing the outer layer (3 mm) with a pre-cleaned stainless steel band saw (wiped 3 times with acetone, followed by multiple cuts through a frozen block of ultra-pure water, 18 M Ω cm quality), followed by rinsing the samples with ultra-pure

Radiocarbon Dating. C-14 is made by the interaction of cosmic rays with nitrogen in the upper atmosphere.
