Description:
40Ar/39Ar geochronological studies were performed on basalts taken from the bottom of Hole 462A. An age of 129.7 ± 4.6 Ma was obtained for two temperature fractions (800 and 1000°C) of Sample 462A-109-1, 106-108 cm. That age is between the age of the oceanic basement, as deduced from the magnetic anomaly data, and the age of interlayered sediment, as deduced from the sparse fossil content.
