Lithology and Thickness
Axial Volcanics Fm:
LITHOLOGY = Basalts extruded along the axes of the rifts display symmetric magnetic anomalies, out to possibly anomaly 2A ( 4 Ma) (Hall, 1970, cited in Barberi and Varet, 1977), and the ages of the basalts progressively increase away from the rift axes.
CALIBRATION = 60% up in the Recent-Pliocene.
