Abstract


Analysis of summed probability density functions (PDFs) of radiocarbon and luminescence dates from discontinuous profiles of river deposits against the background of climate changes recorded
in 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.
