FIGURE 5.2 (A) Continent-continent collision. (B) Continent-ocean collision with buckling-up of the
continent and subduction of the ocean floor. (C) Obduction of the ocean floor over the continent
with later isostatic rise to form mountains. (D) Thrusting of sediments onto the continental plate
with foreland folding at the front. (E) Thrusting of sediment under the continent, where they may
melt and form granite. (F) Crustal thickening from plate collision, possibly accompanied by grav-
ity of sliding rocks near the surface. (From Oilier and Pain 2000.)
