title: Fission track age of magnetic anomaly 10: a new point on the sea-floor spreading curve.
abstract: A portion of basaltic glass retrieved from an abyssal hill in the northeast Pacific has been dated by the fission track method. The sample location corresponds to magnetic anomaly 10 believed to have resulted from sea-floor spreading. The age of this sample is 35 +/- 5 million years, which is in agreement with the previously proposed age of 31 to 32 million years based on linear extrapolation of measured recent spreading rates. This observation upholds the suggestions of other authors on the time variation of sea-floor spreading for the last 30 million years in various parts of the world ocean basin.
