Abstract

Atwater and Macdonald have suggested that oblique spreading occurs at mid-ocean ridges which spread slowly (half rate less than 3 cm/yr), while the spreading is perpendicular at faster-spreading ridges. This paper explores this relation using the ratio of the power dissipated at ridges to that on transform faults to find the angle of oblique spreading (θ). The dependence of the energy dissipation rate on spreading rate is included in simple models of a ridge and transform. These arguments suggest that θ is related to the half spreading rate approximately by sin θ ∼ V-1.
