Evidence for magmatic carbon bias in 14C dating of the Taupo and other major eruptions

Evidence for magmatic carbon bias in 14C dating of the Taupo and other major eruptions

Correlations between prehistoric eruptions and other phenomena depend on accurate dating of the eruption. Here the authors show that magmatic CO2 in groundwater can bias radiocarbon ages for eruptions and that plateaux of carbon isotopic values in tree ring sequences biased by magmatic CO2 foreshado...
