Overview 40Ar/39Ar data of the West Pacific Seamount Province |
| In this table we review new 40Ar/39Ar age results together with all previously published ages for the West Pacific Seamount Province or WPSP. Conventional K-Ar ages have been omitted from this compilation since these ages may be inaccurate due to pervasive seawater alteration. |
