Un till de déformation du Pléistocene inférieur à la basé de la Formation du Lannemezan (Piémont des Pyrénées Atlantiques, France)

, 1992
A deeply weathered diamicton, more than 1,40 m thick and with numerous slickensides has been uncovered at the lower part of the «Formation de Lannemezan» (alluvial cone of Belair).

Sedimentology and geomorphology of tufa barrages on rock coast shore platforms

Sedimentology, Volume 72, Issue 7, Page 2173-2200, December 2025.
ABSTRACT Despite tufa deposits being widely distributed and increasingly recognised globally on rock coasts, their distribution in the tidal frame and geomorphology is poorly understood. The distribution, sedimentology and geomorphology of tufa barrages on supratidal rock coasts are assessed and their controls established.

The eastern extent of the Barents-Kara ice Sheet during the Last Glacial Maximum based on seismic-reflection data from the eastern Kara Sea

, 2008
We present sub-bottom profiling (sparker and Parasound) results from the eastern Kara Sea, on the Eurasian Arctic margin, which enable the identification of the Last Glacial Maximum (LGM) ice extent.

Inner Asian Agropastoralism Within the Mongol Empire: Multi‐Proxy Investigations at Sel'Ungur Cave, Kyrgyzstan

Geoarchaeology, Volume 40, Issue 6, November/December 2025.
ABSTRACT Agropastoralism has been a widespread subsistence strategy in Central Asia from prehistory to the present. While significant research has aimed at understanding past agropastoral communities in the region, reconstructing a generalized economic model remains challenging due to the complex topographic and ecological conditions, as well as its ...

Diamicton in Besiekierz (Central Poland) : how to avoid misinterpretation of superposition in Quaternary geology

, 2013
Diamicton in Biesiekierz (central Poland), whose age and origin has long provoked debate, is located above unquestionable Eemian biogenic deposits documented by palynological and Cladocera analyses.

Glacial-marine or subglacial origin of diamicton units from the southwest and North Iceland shelf: Implications for the glacial history of Iceland

The extent and timing of ice advances onto the north and southwest Iceland shelf is reconstructed by identifying the depositional environment of four diamicton units present in two marine cores from shelf troughs. We analyze a combination of properties,

Influence of catchment lithology on debris‐flow fan morphology, sedimentology and evolution—Field evidence from the White Mountains, southern California, USA

Earth Surface Processes and Landforms, Volume 50, Issue 13, October 2025.
Morphology of the (a) Sacramento Canyon fan (with a catchment dominated by batholitic bedrock) and (b) Gunter Creek fan (with a catchment dominated by sedimentary bedrock) at the foot of the White Mountains, California, highlighting the differences between fans fed by contrasting lithologies.

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,

Sedimentology of placer gravels near Mt. Nansen, Central Yukon Territory

, 1993
Bibliography: p. 172-180.Unconsolidated sediments in the Mount Nansen area can be subdivided into eight elastic facies: I) clay-rich diamicton; 2) massive/stratified silt/clay; 3) massive/disorganized pebbly sand/sand; 4) stratified pebbly sand/sand; 5 ...
