Abstract

Soil genesis and classification studies were carried out in three selected regions of Fars, Bushehr, and Khuzestan provinces, in southern Iran. CARBONATE EVOLUTION was the main pedogenic process; however, the degree of calcic horizon development was different in various regions. In spite of ustic moisture regime in soils of Kheir Abad plain, in Khuzestan province, which have mainly originated from recent deposits, profile development is limited only to the formation of cambic horizon and thin calcic horizon. On the other hand, soils of Darab plain in Fars province, with aridic border to ustic moisture regime, show the most developed calcic and cambic horizons and also mollic epipedon. Profile development in Darab plain is probably due to greater landscape stability and also presence of ground water and denser vegetative covers. Soils of Dashte Palang region in Bushehr province with aridic moisture regime, and scarce vegetative covers, show the intermediate stages of calcic horizon formation. Mineralogical analysis indicated little difference in type of CLAY MINERALS between different areas and different members of top sequence. However, the amounts of CLAY MINERALS are different due to weathering condition, which is affected by internal drainage. Transformation processes could be the origin for the formation of smectite and palygorskite CLAY MINERALS in Dashte Palang and Kheir Abad, while in Darab plain due to more favorable drainage conditions, neoformation seems to be dominant.
