Title

STUDDING GEOMORPHOLOGICAL HERITAGES OF QUATERNARY GLACIERS AND CHANGES IN MORPHOCLIMATIC AND MORPHODYNAMIC SYSTEMS IN THE KHEZRABAD BASIN-YAZD

Abstract

 In central Iran, and at its heights, especially within mountainous valleys, there are landforms that cannot be found in the current climate conditions. Most researchers find these landforms related to QUATERNARY glacial periods and ice performance. In the research, we will try to find and justify glacial landforms in the Qezrabad basin. Qezrabad basin located in the south-west of Yazd city in the west slopes of Shirkuh Mountain along 31Ao 48A´7" to 32Ao of northern latitudes and 53Ao 49A´ 42" to 54Ao of eastern longitudes. This research has been performed on the basis of field studies and direct observation of glacial landforms. But, we studied topographical and geological maps and also aerial photographs, at first. The resulted information of the maps was controlled with GPS system in the field. Results showed two major erosional processes occurred in the Qezrabad basin at the base of a glacier. First, deposition process includes moraines, tills, TILLITE, and erratic. The second process of erosion involves the abrasive action involve QezrAbad broad valley and cirques. Results show glacial traces for two periods, probably the first and the latest In the Qezrabad basin in Pleistocene. TILLITEs laid as unconformity layer on the bedrock (shale stone) indicate the first glaciation, and tills and moraine on the slope and aside of the river indicate the latest. Besides, erosions, glacial sediments, broad valley, and cirques are additional heritages to confirm glaciated the basin. Erosions have descended to the height 1560 meters. The height is the boundary of glacier setting in QUATERNARY in the Qezrabad basin. As a result, the setting of morpho-climatic and morpho-dynamic for glacier period in comparison with present so that the glacier setting has been replaced with sub-glacier setting.
