Description
This upload contains the 40Ar/39Ar geochronology age determination of sample D4-5 (KH-17-J01-D4-5) from Ontong Java Plateau in Pacific Ocean (Ontong Java Plateau) and was calculated using the ArArCALC freeware. The preferred age of 111.16 ± 0.05 Ma is the age plateau and is interpreted as the eruption age of the sample. Eruption age plateau The age determination was carried out on a sample of basalt (plagioclase) in an incremental heating experiment and using the bulk laser heating extraction method. The analyses were run on a ARGUS-VI mass spectrometer and the ages were calculated relative to flux monitor FCT-NM (1E5-21) (sanidine) with an age of 28.201 ± 0.082 Ma. This sample was collected by Takashi Sano (sano@kahaku.go.jp). Sample Description: Standard full leach + 5 min 5% HF.
