The Oldest Known Eocene Loess in the Western United States: Evidence From a Fluvial‐Eolian Transition Zone

Journal of Geophysical Research: Earth Surface, Volume 131, Issue 8, August 2026.
Abstract The timing, stratigraphic development, and mechanisms of late Paleogene loess deposition remain poorly understood, yet they are critical to understanding how tectonics, fluvial reworking, and eolian transport interacted during a key interval of western North American landscape evolution.

Geomorphology of the mouth of the Arosa estuary (Coruña-Pontevedra, Spain)

Journal of Maps, 2017
This paper presents a geomorphological analysis of the littoral zone of the Arosa-Pontevedra estuary mouth and identifies geomorphological units and categorizes them into morphogenetic systems.

Fault Migration and Basin Evolution During Complex Rifting: Examples From the Western North Gulf of Evia, Greece

Basin Research, Volume 38, Issue 4, July–August 2026.
The Western Basin of the North Gulf of Evia rift is a complex, normal fault‐controlled basin. In this study we develop the first pre‐Holocene syn‐kinematic age model here and apply it to better understand rift evolution, basin control, and timing of fault migration in the active rift.

Mid‐infrared spectroscopy applied to a multi‐level cave system (Montmaurin, SW France): An innovative method for assessing sediment provenance

Sedimentology, Volume 73, Issue 5, Page 1722-1749, August 2026.
ABSTRACT Deciphering sediment provenance is essential to understand depositional patterns and dynamics. This question is particularly important in archaeological contexts to constrain the sedimentological history of unearthed material—an information critically needed, for example, to estimate the age of the deposits—or to apprehend sediment movement ...

Bed‐scale quantitative discrimination of hyperpycnites from intrabasinal turbidites—Results from a channelised slope system in the Upper Carboniferous Westward Ho! Formation, United Kingdom

Sedimentology, Volume 73, Issue 5, Page 1750-1798, August 2026.
ABSTRACT Features considered indicative of hyperpycnites and intrabasinal turbidites overlap. Outcrop study presented here suggests that the Westward Ho! Formation forms an 800 m high deepwater‐slope system dominated by hyperpycnites. Taking this unit, and other successions where hyperpycnites have been described, as having been deposited solely from ...

Extreme Events Reshape Flood Hazards Through Sediment‐Induced Channel Change in Southern Taiwan

Geophysical Research Letters, Volume 53, Issue 14, 28 July 2026.
Abstract Extreme precipitation events can cause long‐lasting changes to river systems, altering flood hazards beyond the initial disaster. We investigate how Typhoon Morakot (2009) impacted flood inundation patterns across four river catchments in southern Taiwan.

Synchronous Advance of the Alpine Glaciation Across the Northern and Southern Tibetan Plateau During the Mid‐Pleistocene Transition

Geophysical Research Letters, Volume 53, Issue 14, 28 July 2026.
Abstract Chronological studies of glacial sediments from the Shishapangma and Yarlung Tsangpo River valley indicate that Quaternary glaciation on the southern Tibetan Plateau commenced at ∼0.75–0.83 Ma. However, the oldest glacial deposits in the northern plateau are dated to only ∼0.46 Ma, markedly later than the Middle Pleistocene glacial ...

Gentle Slopes and Fluvial Terraces around Mt. Shokanbetsudake, Hokkaido

Annals of The Tohoku Geographycal Asocciation, 1987
This paper discusses the paleoenvironment of eastern slopes of Mt. Shokanbetsudake, Hokkaido, on the basis of evidences of gentle slopes and fluvial terraces.The fluvial terraces are classified into five surfaces (terrace I to V in descending order) and the gentle slopes into two surfaces (gentle slope I and II). In most case, gentle slope I and gentle

Palaeochannels of the upper central Murray and lower Goulburn rivers, southeastern Australia

Journal of Maps
Palaeochannel systems are characteristic of alluvial plains across large parts of the Australian continent, but their evolution and modes of formation are still only partly understood.
