Effects of Quaternary glaciers on the Binalood Heights and their impact on the development of Neyshabur plain civilization

In this study, morphological indices, climatic and climatic evidence were used to identify icebergs. The permanent snow line was determined by Wright method and showed that at present the average annual temperature is 0 degrees Celsius at 2543 m and there are 65 circuses in the area confirming that circuses are one of the sources of nutrition. They have been very rich in forming ice sheets in the region. Climatic evidence shows that not only was the Quaternary temperature about 13 degrees colder in the study area, but its precipitation was almost twice as high as the present. The city of Neysahabur is a plain surrounded by highlands on the one hand, and the presence of glaciers in the highlands of the region has not been affected by the recent expansion of Neyshabur banization in the region. Geomorphic effects such as permanent snowstorms, Thiel, Moren, glacier tours and circuses indicate that development and civilization in the study area were affected by glacier factors.
