Weichselian glaciations in the middle Notec River region, northwest Poland
… on correlation of stratigraphical position, clast lithology, fabrics and grain size composition of till units. The lithostratigraphy covers two glacial advances of presumed Weichselian (Vistulian) age. The ice flow pattern during these glacial events was reconstructed using directional …

The Dynamics of the Late Neogene Antarctic Ice Sheets in the Central Ross Sea using a Multianalytical Approach
… data was compared to neodymium isotope and clast lithology datasets from collaborators. Site U1522 shows three distinct provenance shifts from the late Miocene to the Pleistocene, two of which are coincident with Ross Sea Unconformities three and two. Late Miocene samples have abundant …

Late Pleistocene Stratigraphy And Events In The Asbestos-valcourt Region, Southeastern Quebec
… provenance. Till geochemistry as well as till clast lithology and fabrics indicate that drift unit A was deposited by a glacier that was advancing westward from Appalachian outflow centers. However, the presence of some northwest-derived clasts in till of drift unit A provides evidence for an …
