Annex 6 - Ar/Ar Dating - BRA23-14A-355u gls.full

This file contains the raw data collected and calculations used during the 40Ar/39Ar dating of the glass fragments hand-picked from the 355-400 μm fraction (after crushing) of the Geraisite tektite fragment BRA23-14A (selected to avoid any bubble or inclusions). Details about the methodology can be found in the \"40Ar/39Ar Dating\" section of the Supplemental Material of the paper: Crósta, A.P., Silva, G.G., Ferrière, L., Nonnotte, P., Libowitzky, E., Jourdan, F.
