Abstract

Measurements of the crest of the spreading ridge in the young ocean basins of the Afar region and Gulf of Aden and in the mature Indian, Atlantic, and Pacific Oceans show that the depth of the ridge crest is correlated (r = 0.99) with the logarithm of the age of the ocean basin. Ridge crests in a very young basin (Afar) are at sea level, at about 1.5 km in young basins (Gulf of Aden), and at about 2.6 km in mature basins (Indian, Atlantic, Pacific). A new curve that relates crestal depth and age of the ocean basin is coupled with the existing depth/age curve for oceanic crust in a comprehensive scheme which can be used for relating depth and age of oceanic crust.
