Oceanic islands

  • Marjorie Wilson

Abstract

In Parts 2 and 3 it was established that some 90% of present-day volcanic activity is concentrated within or adjacent to zones of plate divergence or convergence. Nevertheless, within the ocean basins numbers of seamounts and volcanic islands occur at locations far from adjacent plate boundaries, and these are examples of intra(within)-plate volcanism.
