Multichannel seismic images from the East Pacific Rise 17 o 10'-17 o 40'S are used to study the geometry of seismic layer 2A in the near axis region. Assuming layer 2A corresponds with the extrusive crust, these data are used to study the relationship between volcanism and tectonism in the accumulation of the extrusive layer and to assess the contribution of extrusives to ridge-crest...
