   The action of being pushed or drawn beneath another object.

   The process of one tectonic plate moving beneath another and sinking into the mantle at a convergent plate boundary.

   • Therefore, both a mantle plume and also the subductions of the oceanic plates may have mutually contributed to create the magmatic zone.
   • Evidence for a subduction polarity flip is clear in the Irish Caledonides, where the S-dipping slab beneath the Lough Nafooey arc (Dewey & Ryan 1990; Clift & Ryan 1994) became a N-dipping subduction zone after the Grampian Orogeny.
   • Earthquakes on the subduction interface itself are low-angle thrusts in the depth range 15–45 km, generally reaching a maximum depth of 20 km in the west and 45 km in the centre of the arc, near Crete.

      A surjection between diffeological spaces such that the target is identified as the pushforward of the source.

      • Accordingly, a diffeological principal S¹-bundle over a diffeological space X is a subduction π : P → X and a smooth map τ satisfying the same conditions; see [30] for a thorough discussion.
