Description
This upload contains the 40Ar/39Ar geochronology age determination of sample D7-8 (KH-17-J01-D7-8) from Ontong Java Plateau in Pacific Ocean (Ontong Java Plateau) and was calculated using the ArArCALC freeware. The preferred age of 114.59 ± 0.15 Ma is the combined age plateau and is interpreted as the eruption age of the sample. Combined eruption age plateau from the two samples from D7 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 (1E10-21) (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. Sample Treatment: The two samples from D7 combined.
