The Study of Origin and Some Characteristics of Pre-existing Rocks in Al-Qaim, West of Iraq

Al-Qaim area has been chosen as typical area for western and southwestern parts of the Euphrates River to investigate their soil physical properties and classification. This is due to great soil and bed rock similarities. Two types of soil samples were performed one of them is surfacial and the other 0.3m deep. Several boreholes and vertical pits were used throughout this study.
The study reveals that there were two types of soils; the residual (Sandy loam) and transported soil (Loamy sand). It is also revealed difference in their field density. These types of soils are loose and are regarded agriculturally has bad physical properties. The results show that the residual soil varied in thickness between (0.0-2.4) m whereas, the transported soil reached 3.5m. particularly in wadi cliffs.
