Abstract

The present-day climate of central Iranian Plateau is under the influence of arid and hyper-arid conditions. However, geomorphological evidence suggest that major environmental changes occurred during the last Quaternary. This research studies aerial photographs, geomorphological and sedimentological records of Ardakan Kavir (playa) in central Iran. A major inactive aeolian dune system (locally called kuhrig), has also been studied to determine the accumulation period of the system. Geomorphological evidence such as glacial deposits in Shirkuh mountains (Yazd - Ardakan catchment area), remarkable palaeoshorelines around Ardakan Kavir and relic aeolian sand ramps (kuhrigs) suggest a significant environmental changes in the area, although lack of a chronological record for geomorphological features prevents a comparative study. Geomorphological and sedimentary records from Ardakan Kavir indicate that a prominent lake occurred in the past, more likely sometime during the post-glacial period. The climatic trend was probably from a cold and relatively dry conditions during the late Pleistocene to a warm condition with a positively balanced moisture available during parts of the Holocene.
