| Abstract | ||
| This study was conducted on some soils of agricultural projects in the middle of Mesopotamian plain representing two physiographic units, river and irrigation canal levees. The aim was to study the nature of mineralogical composition of the studied soil pedons.Nine sites representing the dominant soil series were selected as follows : Ishaqi, Kassawiy, Saqlawiya, Baghdad, Field of the College of Agriculture (Abu-Ghraib), Radhwania, Suwaira, Latifiyah, Great Mussaib. The pedons were described and samples from each horizon were taken for mineralogical analysis. The results of heavy minerals indicated that the opaque minerals did not show specific pattren of distribution within all studied pedons mainly due to the effect of geomorphological processes specially deposition process.The Amphibole minerals were the dominant in the pedons of Suwaira, Latifiyah and Mussaib. The results of light minerals indicated that Quartz mineral was dominant in all pedons due to it’s resistance to weathering and could be inherited from parent material. The results of X - ray indicated that the Smectite minerals group was dominant in all pedons due to the presence of environmental conditions for their formation as well as they were inherited from parent material. | ||
