Abstract

4.12 cm marine core sediment was sub sampled to every 2cm interval with a total of 212 samples. Half part of each undisturbed whole length of the dried core sample(s) was used for studies of environmental magnetic properties such as magnetic susceptibility. The remaining part of the samples were dried at 60 0C, grinded and sieved through 230 mesh size and studied for organic carbon, calcium and magnesium carbonates by titration methods. Magnetic susceptibility measurements were carried out by using Kappa Bridge available in Germany. The obtained results have been interpreted based on the sediment core values of other physical parameters such as rate of sedimentation, age and organic carbon. Increased rate of sedimentation (0.006 to 0.013 cm/year) enhanced the magnetic susceptibility value reflecting its range 0.732x10-3 to 1.426x10-3. Obtained positive correlations relating to rate of sedimentation with calcium and magnesium carbonates and magnetic susceptibility indicating about enrichment of the present sediments with carbonate shells in which biologically derived metals are more.
