Glacial Landforms in Border Mountainous Areas Between Iran and Iraq

Manijeh Ghahroudi Tali , Ali Naeimi and Rasoul Hassani Gharnaie

Background: Iran and Iraq political border in the West of Azrbaijangharbi province in Iran and Arbil and Soleymanieh provinces in Iraq coincide with a mountain region with North to South ridge that is named Ghandil mountain. Border area, insecurity and hard to access to mountain get landforms of this area in the unknown condition. Based on Pedrami research only one part of Gandil mountain that is contain Abkhoreh, Bikos and koper next to Zab-e-kouchak river is accessible and had a research. Materials and Methods: In this study topography map (1:25000), elevation data of Aster sensor, field study and sediment sampling were the main material of research. For determining of snow-line in the past period based on Wright method, 60% of cirques defend by field, elevation data and satellite image processing determined. Roundness and sphericity analysis used sediment samples of 40 cm depth. About 50 coarse grains of each sample have been prepared for roundness and sphericity analysis and also100 g of each sample based on sieve shaker until 0.63 microns analyzed for granolometry. Results: Snowline elevation in the study area found in the elevation of 3162.8 m a.s.l., based on differential equation of cirques elevation delta in combine with isoline that is merged with location of 60% of cirques quantity. Also, part of Gandil mountain that is located in Iran boundary we face lots of big glacier valleys. The biggest glacier valley named Seikh Aysh with West-east ridge. In the location of this valley that is conjunction location of West-east valleys, Chorrin and Drosepi valley found lots of signs that are related to glacier sediments in the elevation of 1740-220 m. In the lowest part of Badinawe, Pradanan and Abkhordeh rivers found 4 alluvial terrace that describe last period climate changes. Conclusion: The signs of glacier erosion and accumulation are the main cause for determining the area of glacier coverage areas. Meanwhile, the study in Iran glaciers barrier line are showed that elevation of 3162.8 m a.s.l., is the barrier elevation for determining glacier and pre glacier areas, while the result of this study that achieved based on sedimentology analyses of samples, surveying of cirques and other glacier signs in the field observation in combine with result of regression analyses between temperature and elevating showed that barrier line for determining glacier barrier line is different.
