fracture zone that ofisets the Mid-Atlantic Ridge at 24°N, 45°W was traced westward over a distance of 840 kilometers. The radius of curvature of the fracture zone changes at about 47°45'W; this suggests that the fracture zone was generated by rotation of crustal plates about at least two sequential poles.
