    Morfología Fluvial.-Vertisols (as paleosols) with its related gigants land cracks as a disaster in central Iran deserts
    Akhavan Ghalibaf, M.; Alhoseini Almodarresi, B.B.S; Universidad de Murcia
    ABSTRACT This paper discuses the genesis of land cracks and land depression as one of the clayey desert futures in Central Iran. The origin of this future has been issued after downfall of ground water pressure. The clay mineralogy showed that the swelling clays of smectite groups (like as beidellite) as vertisols can be mainspring for this limitation future in Central Iran. It concluded that pedogenesis in the paleoclimates was effective to form these smectite groups of minerals in paleosoils of Yazd, Central Iran.
