Description
This upload contains the 40Ar/39Ar geochronology age determination of sample RR1310-D14-01 from Rurutu Hotspot in Tuvalu (Rurutu Hotspot, Tuvalu) and was calculated using the ArArCALC freeware. The preferred age of 43.67 ± 0.28 Ma is the age plateau and is interpreted as the eruption age of the sample. A short but reliable plateau with an atmospheric intercept and a low MSWD. The age determination was carried out on a sample of basalt (groundmass) 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 (2A40-14) (sanidine) with an age of 28.201 ± 0.082 Ma. This sample was collected by Kevin Konrad (Konradke@oregonstate.edu). Sample Description: 1x leach. Sample Treatment: Use this link to download the ArArCALC 40Ar/39Ar age calculation files (in the XLS, XML, PDF, AGE and META formats) and any other digital object related to the RR1310 sample from the EarthRef.org Digital Archive.. Location Description: Nukufetau, Pacific Plate, Pacific Ocean.
