Distinguishing characteristics of Diamictons at the Margin of the Matanuska Glacier, Alaska [PDF]
Annals of Glaciology, 1981 The origins of diamictons deposited at the Matanuska Glacier are identified in stratigraphic sequences mainly by the presence or absence of a pebble fabric, internal structure, and variation in gravel-size clast distribution. These properties correlate with major differences in depositional mechanisms and source material.

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,

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
