The Provenance of Regolith at the Chang'e‐5 Candidate Landing Region
Journal of Geophysical Research: Planets, 2020The upcoming lunar Chang'e‐5 mission is scheduled to land near Mons Rümker, in northern Oceanus Procellarum, and return samples with masses up to 2 kg from depths up to ~2 m.

Abstract The lunar regolith consists of the fragmental unconsolidated mantle which overlies more consolidated or crystalline rocks at the surface of the moon. The thickness of the regolith ranges from a few meters in some areas overlying mare basalt flows to tens of meters over much of the highland terrain.

Surface regolith and environment of comets
Planetary and Space Science, 1994Abstract A model for the formation of regolith at cometary surfaces is proposed which is based on the observational fact that comet nuclei release particles with sizes in the micrometre to the decimetre range. The particle emission mechanism is appropriated not only to accelerate particles to escape velocity, but also to “launch” them into orbits ...

Evidence of space weathering in regolith breccias I: Lunar regolith breccias [PDF]
Meteoritics & Planetary Science, 2005 Abstract— We have analyzed a suite of lunar regolith breccias in order to assess how well space weathering products can be preserved through the lithification process and therefore whether or not it is appropriate to search for space weathering products in asteroidal regolith breccia meteorites.

Regolith evolution and geochemical dispersion in transported and residual regolith – Bronzewing gold deposit [PDF]
Geochemistry: Exploration, Environment, Analysis, 2001 Geochemical dispersion in the regolith was investigated at the Bronzewing gold deposit in a variety of geomorphological environments. A series of economic gold deposits are concealed by 5–35 m of sediments, and a thick residual profile about 100 m thick.

Regolith research in Australia
Australian Journal of Earth Sciences, 2017Regolith science is a multidisciplinary, comparatively recent field, having evolved from several older disciplines: geology, geomorphology, soil science, and geography.

The role of clay minerals in formation of the regolith-hosted heavy rare earth element deposits
American Mineralogist, 2019Rare earth elements (REEs) have become increasingly important to our modern society due to their strategical significance and numerous high technological applications.

We derive a new constraint on the thermal and dielectric properties of the lunar regolith layer by reconciling data from the Lunar Reconnaissance Orbiter (LRO) Diviner infrared radiometer and Chang'E‐2 (CE‐2) microwave radiometer (MRM).

On 3 January 2019, the Chang'e‐4 (CE‐4) touched down on the Von Karman crater located inside the South Pole‐Aitken Basin, providing for the first time the opportunity for in situ measurements of the lunar regolith at the farside of the Moon.
