Description
This upload contains the 40Ar/39Ar geochronology age determination of sample MV1203-D37-01 from Omura Guyot in Walvis Ridge and was calculated using the ArArCALC freeware. No meaningful age was determined with this experiment. The age determination was carried out on a sample of trachybasalt (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 (sanidine) with an age of 28.201 ± 0.082 Ma. This sample was collected by Anthony Koppers (akoppers@ceoas.oregonstate.edu). Sample Description: Standard. Sample Treatment: Fine-grained avesicular basalt. Fresh GM, moderately cpx-phyric, sparsely ol-plag phyric..
