Abstract

An investigation of upper mantle structure in the Pacific reveals a systematic difference in depth of the low-velocity layer and shear-wave velocities between continent and ocean. In orogenic regions such as Japan the low-velocity layer is just below the Mohorovicic discontinuity; toward the ocean it is overlain by normal mantle material and in the purely oceanic region it is absent. The so-called low-velocity layer believed to begin at about 60 km depth below the ocean is present in the oceanic region, but shear-wave velocity in it may be a little higher than indicated in earlier works.
