ResumoThe Southeast Sulu Sea is a small oceanic basin that opened in Middle Miocene time in a back-arc setting along the Sundaland margin during subduction of the Celebes Sea plate beneath the Sulu arc. This back-arc extension post-dates compressive tectonism present in this back arc area in early Middle Miocene time. Progressive and still incomplete closing of this basin, initiated in Late Miocene time, is the result of collision of exotic terranes with the Sundaland margin. This collision also induced flipping of the Sulu subduction zone. The Neogene geodynamic evolution of the Sulu Sea provides a modern example of how young oceanic crust can be incorporated within an orogenic belt.
