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

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 ...

Geology and Chronology of the Lunar Taruntius Crater: Implications for the Retention Age of Lunar Ray Patterns and Lifetime of Lunar Explosive Volcanism

Earth and Space Science, Volume 13, Issue 7, July 2026.
Abstract The Taruntius crater, situated between Maria Fecunditatis, Crisium, and Tranquillitatis, is characterized by a prominent bright ray system and a floor‐fractured morphology and has long been interpreted as a relatively young Eratosthenian or Copernican crater.

Loess Studies in Aotearoa New Zealand

New Zealand Journal of Geology and Geophysics, Volume 69, Issue 2, June 2026.
Loess in Aotearoa New Zealand (ANZ) has been studied since its first documented recognition (on Banks Peninsula) in 1878 by Julius von Haast. A decade later, John Hardcastle revealed that southern ANZ loess was both glacial in origin and contained signals of past climates.

Late‐Stage Debris Flows Eroded Aeolis Mons in Gediz Vallis, Gale Crater, Mars

Journal of Geophysical Research: Planets, Volume 131, Issue 6, June 2026.
Abstract How the ancient climate of Mars transitioned to its current cold, hyperarid state is recorded by the sedimentary rocks preserved on its surface. Gale crater, the Curiosity rover landing site, is one such location, where the central mountain, Aeolis Mons, preserves an extensive sedimentary record. Curiosity has demonstrated that the Aeolis Mons

Modeling the Anthropogenic Effects on Watershed Evolution Trajectory: An Example From the Chestatee River in Northern Georgia, USA

Journal of Geophysical Research: Earth Surface, Volume 131, Issue 6, June 2026.
Abstract Human activities shape erosion dynamics and landscape evolution, making effective modeling approaches essential for understanding these impacts. This study utilizes landscape evolution models with a streamlined parameterization process to evaluate the anthropogenic effects on the erosional trajectory of the Chestatee River watershed in ...
