Summary/Abstract: The article presents the results of measurements of the longer axes orientation in the morainic tills at 11 sites and 12 outcrops in zones I–IV of the glacigenic forms in the area between Piotrków Trybunalski, Radomsko and Przedbórz. Zone III located in the western part of the said area corresponds to the well-recognised Widawka lobe in the Łódź region. Zones I, II and IV in the eastern part of the study area associated with the hypothetic Pilica-Luciąża lobe (S part of the Rawka lobe) and both coming from the Warta ice-sheet. Measurements of fabric clasts in zone III proved that the ice sheet has arrived from NNW and NW (330º–340º). In zones I, II, and IV transgression came from the NNE and NE (357º–52º). The lobe reached the Kamieńsk–Rzejowice–Przedbórz line. In the Łódź hump, the meridian belt between Kamieńsk and Łódź fabric tills are of various orientation interpreted as a confluence of the two lobes.
