| Abstract | ||
| Nine boreholes that do not exceed 20m depth were studied in Thi-Qar Governorate to determinate the sedimentary model of this area, so the boreholes were studied from lithological point of view, four beds were identified from bottom to top 1. Dense silty sand bed could belong to the Hammar Formation 2. Medium silty clay silty sand bed 3. Stiff silty clay bed 4. Marly silty clay bed, as well as, the faunal assemblages was determinate one bore hole (B.H9). Depending on the Lithological and paleontological information, three stages of sea level fluctuation were characterized, there are: 1. The maximum of transgression, the shore line covered the region of south east of Mesopotamia but did not reach Shattra and Al-Gharraf cities towards the west 2. Simple regression of the shore line, reached to Nassiriya city borders (BH.5) 3. Rapid regression of the shore line, where the marine sand is disappeared throughout the study sections. | ||
