Crusting and induration surface layer of originally fine-grained loose material.
Synonyms and Related Terms
Duricrust is the cemented surface layer of loose dust on the top of regolith forming hardened, indurated layer (Mutch et al. 1977).
Desert crust is located directly on the top of solid bedrock and not on the regolith and might contain biogenic components (on Earth).
Top down model: at night frost is deposited on the surface, which melts during the daytime and migrates downward assisted by capillary action, dissolving salts that are present. Water evaporates...
