Basalts associated with the formation of the Macquarie Ridge have been radiometrically dated at between 9.7 Ma and 11.5 Ma, giving a Middle Miocene age in approximate agreement with the age indicated by fossils in intercalated sedimentary rocks but younger than suggested by the nearby sea-floor spreading anomaly pattern.
