Cosmogenic nuclide weathering biases: corrections and potential for denudation and weathering rate measurements [PDF]
Geochronology, 2022 Cosmogenic radionuclides (CRNs) are the standard tool to derive centennial-to-millennial timescale denudation rates; however, it has been demonstrated that chemical weathering in some settings can bias CRNs as a proxy for landscape denudation. Currently,

Adsorption of rare earth elements in regolith-hosted clay deposits
Nature Communications, 2020 Global resources of heavy Rare Earth Elements (REE) are dominantly sourced from Chinese regolith-hosted ion-adsorption deposits in which the REE are inferred to be weakly adsorbed onto clay minerals.

Perchlorate and Agriculture on Mars
Soil Systems, 2021 Perchlorate (ClO4−) is globally enriched in Martian regolith at levels commonly toxic to plants. Consequently, perchlorate in Martian regolith presents an obstacle to developing agriculture on Mars.

Anais da Academia Brasileira de Ciências, 2022 Boulders are an important material in debris flow and their source is coupled with spheroidal weathering profiles that produce corestones. The goal of this work was to establish the geochemical transformations that produced corestones and distinguished ...

Gas-Driven Regolith-Sampling Strategy for Exploring Micro-Gravity Asteroids
IEEE Access, 2020 Small celestial bodies contain abundant scientific information to understand the origin and evolution of the solar system. The acquisition and analysis of regolith sample is the most direct and effective way to explore the geological construction of ...

The importance of Phobos simulants: a review on our current knowledge
Frontiers in Astronomy and Space Sciences, 2023 Phobos, a satellite of Mars, was successfully studied by flyby, orbiter, and landing missions to the Red Planet, but several questions remain about its origin, composition, and relationship to Mars.

Fine-regolith production on asteroids controlled by rock porosity
Nature, 2021 Spacecraft missions have observed regolith blankets of unconsolidated subcentimetre particles on stony asteroids1–3. Telescopic data have suggested the presence of regolith blankets also on carbonaceous asteroids, including (101955) Bennu4 and (162173 ...
