Loess cover on the Eastern part of Poland with the location of Tyszowce profile.

Lithology, grain size distribution (Mz), magnetic susceptibility, humus and CaCO3 content for Tyszowce loess section.

Full dose response curves for Tyszowce 1 for quartz (OSL) and polymineral fraction (IRSL), together with typical decay curves (insets). Response curves fitted best to a double saturating exponential.

A diagram presenting the Late Pleistocene loess section at Tyszowce. From the left: lithology, OSL ages, radiocarbon ages and relativeprobability plots for ages obtained for all samples versus depth.

14C ages of loess and soil. The age was calibrated using OxCal program v4.2, (Bronk Ramsey 2009; Southon et al., 2013).

Steps used in protocols which were used for determined equivalent doses. For the medium grain quartz fraction the single-aliquot regenerative-dose (SAR) protocol (Murray and Wintle, 2000) was used. For the polymineral fine grains samples a post-IR IRSL protocol (Thiel et al., 2011) was used.
