An ancient soil or soil horizon that formed on the surface during the geologic past.
Ancient soil preserved in the stratigraphic record.
Paleosol - An ancient soil horizon.
"Old Soil." Buried soil horizons indicative of past soil conditions different from that presently prevailing.
An ancient, buried soil whose composition may reflect a climate significantly different from the climate now prevalent in the area where the soil is found.
a buried soil; a "soil of the past".
A buried soil horizon of the geologic past. See Sellwood and Price (1994).
an ancient soil layer preserved by deposition of younger overlying layers
Soil horizon from the geologic past.
ancient or buried soil, often used as a stratigraphic marker for interglaciation.
Very old, buried soil.
Old, buried soil that may furnish some evidence of the nature of past climates because climate is the most important factor in soil formation.
soil exhibiting features that are the result of some past conditions and processes.
In soil science, paleosols (spelt palaeosols in Great Britain and Australia) can have two meanings. The first meaning, is simply that of a former soil preserved by burial underneath either sediments (alluvium or loess) or volcanic deposits (Volcanic ash), which in case of older deposits, have lithified into rock. In Quaternary geology, sedimentology, paleoclimatology, and geology in general, it is the typical and accepted practice to use the term "paleosol" to designate such "fossil" soils found buried within either sedimentary or volcanic deposits exposed in all continents as illustrated by Rettallack (2001), Kraus (1999), and innumerable other published papers and books.
