Description
This upload contains the 40Ar/39Ar geochronology age determination of sample 192-1185A-10R-3W 40/55 (192-1185A-10R-3W 40/55) from Ontong Java Plateau in Western Pacific Ocean (Ontong Java Plateau) and was calculated using the ArArCALC freeware. The preferred age of 111.41 ± 0.22 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 (5A6-21) (sanidine) with an age of 28.201 ± 0.082 Ma. This sample was collected by Peter Davidson (davidspe@oregonstate.edu). Sample Description: Full standard leach + 5min 5% HF.
