摘要：

The Kane fracture zone has been traced as a distinct topographic trough from the Mid-Atlantic Ridge near 24°N to the 80-m.y. B.P. isochron (magnetic anomaly 34) on either side of the ridge axis for a total of approximately 2800 km. Major changes in trend of the fracture zone occur at approximately 72 m.y. B.P. (anomaly 31 time) and approximately 53-63 m.y. B.P. (anomaly 21-25 time) which are the result of major reorientations in spreading directions in the central Atlantic Ocean. © 1979.
