CORRELATION OF THE LATE CENOZOIC ENDOGENIC EVENTS AND CLIMATIC VARIATIONS IN CENTRAL ASIA

Yarmolyuk V.V.; Kuzmin M.I. (2006)

Trend of climatic changes in geological history of the Earth was determined by gradual decrease in the global surface temperature. Substantial deviations from this trend depended on the prevalent type of volcanism: ...
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 ...
