A Semi Automated Technique to Regolith-Landform mapping in West Africa. [PDF]

ASEG Extended Abstracts, 2007
Large regional airborne surveys have been flown over much of Nigeria, Niger and Ghana the data collected (mag spec and gamma radiometrics) in conjunction with Landsat ETM7+ and Shuttle Radar Topography Mission (SRTM) data sets are being used to create Regolith- Landform maps.

Automated regolith landform mapping using airborne geophysics and remote sensing data, Burkina Faso, West Africa

Remote Sensing of Environment, 2018
Abstract We have studied the regolith landform distribution in the area of Gaoua, western Burkina Faso, using an integration of geophysical and remote sensing data. Concentration maps of K, Th, U, as well as their ratios, were computed from airborne gamma-ray spectrometry data to assess the geochemical composition of the regolith.

Geochemical Pathways Defined by Predictive Regolith-Landform Models Using TanDEM-X Data in the Tanami Region, Australia

Earth Science, Systems and Society
The Granites-Tanami Orogen (GTO) is a significant auriferous province located in the poorly exposed southwestern part of the North Australian Craton. This paper looks at the data sources that are suited to studying regolith-landform in areas such as the ...

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 ...
