Abstract

A comparative study in arid and semiarid areas of Israel, supported by micromorphological analysis, has shown that the nari develops within the host chalky material or calcareous sandy material and not in the soil material. Three phases have been distinguished in the formation of the nari: a subterraneous phase involving a discontinuous layer of blocky fragments disintegrated in situ from the top part of the upper layer; a surface phase, in which the morphological differentiation of a nari profile shows a surface with a laminar crust produced by lichens which trap airborne dust particles; and an alteration phase characterized by the formation in the upper part of the hard layer of a mosaic like layer. -from Authors
