摘要：The paper presents the results of new studies of Quaternary deposits filling the Kleszczów Graben in the Szczerców outcrop, Bełchatów Lignite Opencast Mine. Sedimentary successions were profiled in the fieldwork. Moreover, the borehole data were studied. Laboratory studies included: grain size analyses, analyses of shape and morphology of quartz grain (morphoscopy), analyses of anisotropy of magnetic susceptibility (AMS), palynological, malacological and ostracodological studies, as well as geochronometric (C14) and geochemical (δ18O/δ16O) measurements. The studies were carried out in 2009–2013 and resulted in discovering of some sedimentary formations as well as arranging geological cross-sections and synthetic lithostratigraphic profile. The following sedimantary formations have been distinguished: Folwark, Kuców, Czyżów, Ławki, Rogowiec, Aleksandrów, Piaski and Widawka, arranged into two structural units: the lower one – deformed, and the upper one – undeformed.
