Morphometry and spatio‐temporal evolution of salt karren

open access: yesEarth Surface Processes and Landforms, Volume 50, Issue 8, 30 June 2025.
Analysis of salt karren (pits, flutes, bevels and pedestals) using high‐resolution, multi‐temporal 3D models generated by SfM photogrammetry Morphometric characterisation and comparison with karren in other lithologies Complex evolutionary patterns of flutes and bevels and rapid vertical growth of pedestals Abstract Morphometric data on karren ...

Uranium and Lithium Isotope Ratios of River Solutes Clarify the Role of Bedrock Properties in Landscape Denudation

open access: yesGeophysical Research Letters, Volume 52, Issue 12, 28 June 2025.
Abstract Rock weathering impacts global nutrient cycles but factoring intrinsic properties of bedrock into weathering models remains a challenge. Here we show that two common tracers of silicate weathering—uranium (U) activity ratios and lithium (Li) isotope ratios of river solutes—inform lithology‐specific modes of landscape denudation.

Integrated Seismic Refraction, Reflection, and Rayleigh Wave Imaging at Kilbourne Hole, New Mexico: Implications for Lunar Subsurface Exploration

open access: yesJournal of Geophysical Research: Planets, Volume 130, Issue 6, June 2025.
Abstract Maars are volcanoes with a central crater surrounded by an ejecta ring formed through surface explosive processes from underlying magma interacting with fluids. The study of terrestrial maar volcanoes, as analogs to explosive volcanic vents on the Moon and other planets, can improve our understanding of planetary volcanism and evolution.

Geomorphological Evidence of Near‐Surface Ice at Candidate Landing Sites in Northern Amazonis Planitia, Mars

open access: yesJournal of Geophysical Research: Planets, Volume 130, Issue 5, May 2025.
Abstract This work presents geomorphological analyses of an area at the boundary between Arcadia Planitia and northern Amazonis Planitia, situated in the northern mid‐latitudes of Mars. Recent studies have indicated the presence of substantial volumes of near‐surface excess ice in Arcadia Planitia, making this region a promising candidate for future ...

Infiltration Dynamics on Early Mars: Geomorphic, Climatic, and Water Storage Implications

open access: yesGeophysical Research Letters, Volume 52, Issue 8, 28 April 2025.
Abstract On early Mars, the integration of surface, groundwater, and climate systems into an integrated hydrological system remains poorly understood. The partitioning of precipitation, between surface and groundwater via infiltration, controls the Martian aquifer recharge rates and, subsequently, surface erosion processes.

Distribution and palaeoenvironmental significance of mountain blockstreams in the southern hemisphere

open access: yesJournal of Quaternary Science, Volume 40, Issue 3, Page 537-557, April 2025.
ABSTRACT Openwork mountain block deposits (blockfields, blockstreams) have received much research interest globally given their visual appeal as prominent cold‐region landforms. However, studies have shown that these landforms in both glaciated and non‐glaciated environments are probably of considerable age (pre‐Quaternary), yet the environmental ...

Construction, destruction and fan‐river coupling dynamics during two consecutive debris flow events in an arid fluvial system

open access: yesEarth Surface Processes and Landforms, Volume 50, Issue 4, 30 March 2025.
Debris flows into tributary‐junction alluvial fans contributing to both their formation and destruction. In northern Chile, we estimated the geomorphic changes caused by two consecutive debris flow events and analysed differences in debris flow sedimentology between them.

The Geoarchaeology of Agricultural Terraces in Europe: Construction, Resilience and Implications for Sediment Delivery

open access: yesGeoarchaeology, Volume 40, Issue 2, March/April 2025.
ABSTRACT Although the primary purpose of agricultural terracing can be assumed to be food production, it has been suggested that a secondary purpose was the control of soil erosion. In this paper, we explore this thesis with multi‐proxy data from the TerrACE project, which studied 20 sites in a latitudinal transect across Europe.
