Vapor Deposits in the Lunar Regolith [PDF]

open access: bronzeScience, 1994
Since the Apollo missions, we have emphasized the following points, which are based on theoretical calculations and on laboratory studies of the properties of evaporated silicate deposits and of lunar samples. The mass of vapor generated by impacts on the lunar surface is comparable in magnitude to the mass of impact melt glasses; the physics of impact

The stratification of regolith on celestial objects [PDF]

open access: yesIcarus, 2015
All atmosphere-less planetary bodies are covered with a dust layer, the so-called regolith, which determines the optical, mechanical and thermal properties of their surface.

Solar wind erosion of lunar regolith is suppressed by surface morphology and regolith properties. [PDF]

open access: yesCommun Earth Environ
Abstract Important aspects concerning the origin and formation of the Moon’s exosphere, its tenuous gas envelope, remain puzzling with uncertainties regarding the importance of different effects. Two competing processes — micrometeoroid impact vaporization and solar wind ion sputtering — are considered key contributors to the ejection of ...

Regolith map of France

open access: bronzeQuaternaire, 2011
Regolith formations are surficial fragmental and unconsolidated rocks whose genesis and properties result from successive periods of surface processes. They comprise: autochthonous formations resulting directly from successive periods of surface weathering in the upper 200 metres of the Earth's crust; allochthonous formations in which the ...

Objective Regolith-Landform Mapping in a Regolith Dominated Terrain to Inform Mineral Exploration [PDF]

open access: yesGeosciences, 2018
An objective method for generating statistically sound objective regolith-landform maps using widely accessible digital topographic and geophysical data without requiring specific regional knowledge is demonstrated and has application as a first pass ...

The viscosity and processing of molten lunar regolith [PDF]

open access: yesScientific Reports
Establishing a permanent, self-sufficient habitat for humans on planetary bodies is critical for successful space exploration. In-situ resource utilisation (ISRU) of locally available resources offers the possibility of an energy-efficient and cost ...

Lunar meteorite regolith breccias: An in situ study of impact melt composition using LA-ICP-MS with implications for the composition of the lunar crust [PDF]

open access: green, 2010
Dar al Gani (DaG) 400, Meteorite Hills (MET) 01210, Pecora Escarpment (PCA) 02007, and MacAlpine Hills (MAC) 88104/88105 are lunar regolith breccia meteorites that provide sampling of the lunar surface from regions of the Moon that were not visited by ...

Mineral Content Estimation of Lunar Soil of Lunar Highland and Lunar Mare Based on Diagnostic Spectral Characteristic and Partial Least Squares Method

open access: yesApplied Sciences, 2022
Extraction of mineral and rock information of lunar regolith is of far-reaching significance to the study of material composition, geological structure and historical evolution of lunar regolith.

Self-Organization Characteristics of Lunar Regolith Inferred by Yutu-2 Lunar Penetrating Radar

open access: yesRemote Sensing, 2021
Most previous studies tend to simplify the lunar regolith as a homogeneous medium. However, the lunar regolith is not completely homogeneous, because there are weak reflections from the lunar regolith layer.

Cosmogenic nuclide weathering biases: corrections and potential for denudation and weathering rate measurements [PDF]

open access: yesGeochronology, 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,
