Comparison between the RPI record obtained at Sütto and the GLOPIS (Laj et al., 2004) and the PISO stack (cut-out PISO 1.5 Ma; Channell et al., 2009). Correlation intervals for indirect dating. Above depths of 6 m, the RPI signal at Sütto is ambiguous. Nevertheless, based on the reasonable assumption of strongly increased accumulation rates, a possible correlation of the upper part of the section near 4 m to the time span between 22 and 24 ka is proposed.
