  • CROSS CALIBRATION OF K-AR STANDARD MINERALS USING AN UNSPIKED AR MEASUREMENT TECHNIQUE 
    Charbit S.; Guillou H.; Turpin L. (1998)
    We have developed an analytical procedure to intercalibrate the 40Ar content of 40Ar/39Ar and 40K/40Ar standard minerals. This procedure is based on an unspiked volumetric standardisation method developed for K-Ar dating. ...
  • NEW K-AR AGES FOR BASALTS FROM FRANZ JOSEF LAND 
    Grachev A.F.; Arakelyantz M.M.; Lebedev V.A.; Musatov E.E.; Stolbov N.M. (2001)
    New K-Ar age determinations on basalt samples from three drillholes and outcrops on Franz Josef Land suggest that flood volcanism throughout the archipelago fits in a very narrow age interval (116 +- 5 Ma). For 95% of the ...
