Abstract

Seismic profiles from three crossings of the Mid-Atlantic ridge show that total sediment accumulation is small. In the north and middle parts of the ridge the sediments occur mainly in pockets and are unstratified. The basement surface on which they rest is uniformly rough from the crest of the ridge out to the lower flanks and farther outward below the basin sediments. In the south the sediment layer tends toward uniform thickness, and the ridge sediments are mainly pelagic. Study of the profiles, photographs, and sediment cores indicates that total accumulation in the oceans is small compared to that inferred from the accepted Cenozoic rates of deposition, but that relative amounts of carbonate and red clay conform to the accepted ratio of their respective rates.
