A classification of volcanic zones into six different categories is proposed based on the plate tectonic viewpoint (Table 1). They are volcanoes of oceanic ridge axis, island arcs and continental margins, marginal seas, rift valleys, seamounts and intra-oceanic islands, and plateau basalts. Studies are critically reviewed, putting emphasis on compositional characteristics of the volcanic rocks and mode of origin of the magma for each volcanic zones.
