Description :
This study demonstrates that depth of carbonate accumulation in an arid environment is not a linear function of precipitation but is initiated by biogenic processes. Surficial soils and paleosols at the study site revealed that at first a biogenic calcite deposition process occurs by fungi and bacteria mainly around roots and burrows, and is then accompanied by physicochemical deposition as a result of changes in soil permeability.
