Abstract

Eight gravity cores from the active eastern continental margins of the Arabian Sea were dated using 210Pb(xs), 137Cs and 14C. The short-term (≤ 100 years) sedimentation rates range from 0.06 to 0.66 cm/year where as the long-term (≥ 1000 years) ones using AMS 14C on planktonic foraminifera varied from 0.004 to 0.13 cm/year. For long-term chronology (≤ 50000 years) AMS dating of well-cleaned planktonic foraminifera is most suited.
