Radiometric dating of sediment records in Kuwait's marine area

Six sediment cores collected from the Northwestern Arabian/Persian Gulf have been radiometrically dated by Pb-210. Three cores were collected from stations within the Kuwait Bay, and three others were collected from stations outside the bay. Two models have been used for Pb-210 dating of sediment cores, i.e. Constant Flux: Constant Sedimentation (CF:CS) Model and the Constant Rate of Supply (CRS) Model. The average rates were found to vary significantly between 0.16 and 1.00 cm y(-1) for stations outside and within the bay respectively. The variability of the sedimentation rate was essentially physiographic characteristics and variable hydrodynamic condition. In this study, Cs-137 fallout radiotracer was also used to construct a realistic chronology. It was observed that the Cs-137 in the entire vertical profile has been continuously contributed by fluvial and atmospheric deposition.
