| Abstract | ||
| The purpose of present study is to determine the gender of the sediment constituents and attribute sedimentary particles to the lithological units of basin in order to determine the relative importance of each lithology unit in creating sediment. In this study, the first profile is made on the sediment behind the mortar stone dam in Madabad 1 sub basin, located in Ghare Ghoush Khodabandeh, and different samples are collected. Formation is performed for all samples using wet sieving method. Then, sieves of 150 micron, 300 micron and 1.18 mm are selected as standard sieves. After that, 100 grains of sediment from each sample are selected and mineralogical analysis is carried out by using Binocular as well as considering the sedimentary aspects of the area. Particularities of rocks and minerals are determined by counting them and the results are compared with lithologic units by determining the contribution of every mineral and rock fragment. Then, particularities of stone and production unit of each mineral and rock fragment as well as the share of each stone unit in sediment production is determined. According to the obtained results, the share of Qt2 units which include new alluvial, is 34.65 percent. However, the share of M1q lithologic unit, which consists of fossil limestone and bio-micritic, is 65.88 percent. After including the factor of area and calculating the relative importance, it is revealed that the Qt2 unit, with the relative importance of 56.32, in comparison with M1q unit, with the relative importance of 43.68, has greater relative importance in sediment production. | ||
