A Burial History of the Sedimentary Succession Preserved in Aeolis Mons, as Recorded by Fracture Networks at Maria Gordon Notch, Gale Crater, Mars

Journal of Geophysical Research: Planets, Volume 130, Issue 7, July 2025.
Abstract Fractures in sedimentary rocks preserved within Gale crater record the deformational and burial history of the sediment infill. Fracture geometries and morphology can be used to time other geologic events, such as: compaction, diagenesis, fluid migration, geochemistry, and broader tectonic stresses within a basin.

Raised beach deposits and the distribution of structural lineaments on Macquarie Island [PDF]

, 1984
The distribution of previously-unmapped raised beaches on Macquarie Island makes it difficult to accept earlier interpretations of landform evolution.

Characterizing Fractured Zones in Urban Karst Geology Using Leaky Surface Waves From Distributed Acoustic Sensing

Journal of Geophysical Research: Solid Earth, Volume 130, Issue 7, July 2025.
Abstract Urban karst geology poses significant geohazard risks, most notably sinkholes and surface depression stemming from soluble and fractured bedrock that is prone to dissolution and collapse. However, mapping and characterizing these hazards using traditional geophysical surveys in cities is challenging due to dense infrastructure and high levels ...

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

Geophysical 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

Journal 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

Journal 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 ...

Soil surveys: A window to the subsurface [PDF]

, 2005
Soils and underlying parent materials form a continuous system we must understand and manage in total. Numerous concerns (e.g., water quality, on-site waste disposal, landfill placement, and nutrient or pesticide movement) require an integrated knowledge
