Description
Summary:Analysis of summed probability density functions (PDFs) of radiocarbon and luminescence dates from discontinuous profiles of river deposits against the background of climate changes recordedin the NGRIP core.A b s t r a c t. The study presents the results of a comprehensive analysis of radiocarbon and luminescence dates from samples taken from a fluvial environment for selected regions south of the LGM line, presented against a high-resolution INTIMATE stratigraphy. It is shown that discontinuous records of fluvial environmental responses in such an analysis reveal significantly more details than studies conducted at individual sites.A strong correlation is observed between peaks in the PDF curves of radiocarbon dates and interstadial periods, while accumulations of luminescence dates are correlated with stadial periods.
