The diamictons of Río Blanco basin, Cordon del Plata, Mendoza

, 2020
Both the sediments and the geomorphic setting of the diamictons along Rio Blanco on the piedmont east of the Cordon del Plata indicate that they could not have been deposited there by a glacier tongue, as I and several earlier observers have suggesred Rather, they must have been deposits of long-runout debris flows, as argued by Polanski.

Middle to Late Pleistocene valley‐slope cambering: The interglacial basin at Wing, Rutland, England

Journal of Quaternary Science, Volume 40, Issue 7, Page 1230-1239, October 2025.
ABSTRACT A depression in the Jurassic bedrock at Wing, Rutland (eastern England), is infilled by deposits spanning the Late Wolstonian (=Late Saalian) to Early Devensian (=Early Weichselian) substages, including the most complete Ipswichian Stage (=Eemian Stage; ~Marine Isotope Stage 5e) sequence known in Britain. This sequence forms an enclosed pocket,

Ice‐Rafted Detritus of the Southeast Grand Banks Slope, Newfoundland, Throughout Heinrich Layers 1 to 5a: 2. Magnetic Properties

Geochemistry, Geophysics, Geosystems, Volume 26, Issue 10, October 2025.
Abstract Ocean‐wide “Heinrich event” layers marked by weakly magnetic dolomitic ice‐rafted detritus (IRD) from the Hudson Bay region are a prominent signature of Laurentide Ice Sheet surges. Contrary to intuition, the Heinrich layers of the Ruddiman Belt IRD exhibit maxima of magnetic susceptibility. Building on IRD petrology and abundance in sediments
