摘要：

Three Antarctic cores were analyzed for 32Si and diagnostic isotopes of the uranium decay series for sediment accumulation rate determination. The 32Si method gives rates of about 470 mm/103 yr over the last 1000 years and 230Thexcess method gives sedimentation rates of slightly less than 6 mm/103 yr on the 105 yr scale. The 32Si results and the 230Th rates agree with earlier results for the Antarctic region. © 1969.
