(Table 1) Age determinations of basement rocks of DSDP Leg 31

DOI

The origin and development of the Phillipine Sea have been central issues in tectonic studies of a marginal sea: the deep-sea drilling project (DSDP), Leg 31, was primarily intended to resolve the question. Unfortunately, at only two of the Leg 31 sites (292 and 296) were microfossils indicating the age of the basement recovered, so the age of the ocean basin, had to be deduced by dating the drilled basement rocks.

AGE (Ka BP) is the total age.
