Evidence of space weathering in regolith breccias I: Lunar regolith breccias [PDF]

open access: possibleMeteoritics & 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 research in Australia

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

Sedimentary associations and regolith

2010
Sediments and sedimentary rocks as hosts to giant metallic deposits have already been invoked in several earlier chapters like oceanic sediments (Chapter 5); sediments in island arcs and Andeantype continental margins (Chapters 5 and 6, respectively), sedimentary rocks in the volcanosedimentary orogens (Chapter 9) and in early Precambrian greenstone ...

Evaluations of lunar regolith simulants

Planetary and Space Science, 2016
Apollo lunar regolith samples are not available in quantity for engineering studies with In-Situ Resource Utilization (ISRU). Therefore, with expectation of a return to the Moon, dozens of regolith (soil) simulants have been developed, to some extent a result of inefficient distribution of NASA-sanctioned simulants.

Dome Pressurization and Regolith Porosity

Earth and Space 2014, 2015
Long term settlement of lunar or Mars caves or subsurface features on planetary bodies where large pit openings exist provide an opportunity to substantially increase livable volume areas and allow inhabitants freedom from confines of living in modules or enclosed in a cave environment.

Thermophysical Analysis of Regolith on (101955) Bennu: The Coarse Regolith Conundrum

Thermophysical analyses of planetary bodies such as the Moon, Mars, and numerous asteroids have allowed for remote estimates of regolith physical properties, such as particle size and packing density, as well as the relative spatial abundance of boulders.  Here we define “regolith” as a particulate assemblage where most ...

On the depth of the lunar regolith

The Moon, 1970
The aim of this paper is to point out that if the sinuous rilles on the Moon represent trenches in the mare ground in which they meander, the existence of a great number of individual boulders on their slopes - as discovered on the high-resolution photographs taken by US Lunar Orbiters 4 and 5 in 1967 - suggests that the solid substrate of the lunar ...

WATER IN THE MARTIAN REGOLITH

1978
The state of water in the Martian regolith is addressed. The water-ice phase composition, adsorption-desorption and evaporation phenomena, and brine compositions of six antarctic soils that are considered to be good terrestrial analogues of the Martian surface materials are examined.
