Title

GLACIAL EVIDENCE IN SAFA SHAHR'S BASIN IN FARS PROVINCE

Pages

  109-130

Abstract

 The evaluation of glaciology documents of Iran, according to Bobek Deresh, Hagedorn, Schowitzer, Kuhle and others shows that the main point of their analytical interpretations is mostly based on the recognition of permanent snow line and recent glacially-dominated regions. Particularly in the central areas of Iran, despite the recent snow line, which amounts to higher than 5000 meters, and lack of elevations above this limit, there is a speculation over the existence of permanent glaciers, even during the cold period. This point, however, never means that the evidence resulting from the glacier behavior has not been found in the above mentioned areas.Therefore, in order to test the hypothesis of this research, based on the possible creation of geomorphic forms caused by the action of QUATERNARY glaciers in central Iran, the SAFA SHAHR'S BASIN, with an average altitude of 2447 meters above sea level, has been selected. In fact, prior to this research few researchers assumed that Safa Shahr region may have experienced the morphology of forming ice and glacier movement. Based on this research, the evaluation of regional paleoclima by Write Method and preparation of past isotherm and isoheyt maps and their comparisons with their recent conditions show that SAFA SHAHR'S BASIN in its climatical background not only received twice precipitation as much as the recent amount, but also has had a temperature about 8º C lower than the present one.Consequently, during the last cold phase of QUATERNARY, all necessary conditions had been available to prepare adequate snow and ice so that formation could take place by the ice movements in this region. Wide evidence of glacial geomorphic features, such as 94 CIRQUEs, with different dimensions, U shape valleys, lateral moraine and wavy surfaces, along with sedimentary analyses have approved both the results of paleoclima analysis and the use of Write Method. As a result, it has been proved that SAFA SHAHR'S BASIN in anaglacial areas has been widely affected by ice and glaciers.
