“The entire unconsolidated or secondarily recemented cover that overlies more coherent bedrock, that has been formed by weathering, erosion, transport and/or deposition of the older material.” The regolith thus includes weathered bedrock, saprolite, soils, fragmental volcanic material, impact ejecta, glacial deposits, colluvium, alluvium, evaporitic sediments, and aeolian deposits (see Eggleton 2001).



Regolith is the highly variable, usually unconsolidated but sometimes recemented, granular layer at the surface of planetary bodies, overlying bedrock (Clarke 2008). This layer of debris is also termed “soil-like deposit” (on Mars) to distinguish it from terrestrial soils which are mechanically similar but contain organic materials (Moore et al. 1999). McKay et al. (1991) define “lunar soil” as the finer-grained (subcentimeter) fraction of the unconsolidated material (regolith) at the lunar...
