An overview of Mass Accumulation Rates in key Polish loess–palaeosol sequences derived from luminescence chronologies

Loess–palaeosol sequences (LPS) represent one of the most important continental archives of late Quaternary environmental change in Europe. Establishing reliable chronologies is essential for reconstructing dust dynamics and for correlating regional loess stratigraphies. In this study, we present the first systematically derived mass accumulation rate (MAR) dataset for six key Polish LPS, based on high‐resolution Optically Stimulated Luminescence dating of the 45–63 μm quartz fraction. Bayesian age–depth models were constructed using the Bacon software. The results demonstrate pronounced temporal and spatial variability in loess accumulation across southern Poland. All profiles show maximum MARs during MIS 2, with exceptionally high values exceeding 1000 g m −2 a −1 at Trzebnica, Tyszowce and Strzyżów sites. In contrast, Zaprężyn site exhibits lower MARs with only localized peaks. The results highlight the utility of luminescence‐derived MARs for investigating regional aeolian dynamics, while also emphasizing the methodological limitations imposed by chronological uncertainties and sampling resolution.
