Abstract
The sample from Hole 444A in the Shikoku Basin which yielded a radiometric age of 14.7+-2.1my, confirms the estimated age of the sill and supports the thesis of post-spreading, off- ridge volcanism in this part of the basin. The sample from Hole 446A in the Daito Basin which yielded a radiometric age of 48.2+-1.0my, dates from the late early Eocene to early M. Eocene. This age is consistent with the paleontological ages of sediments above and beneath the sill. -from Authors
