Ophiolites originate from oceanic crust and mantle material generated by seafloor spreading at oceanic ridges or marginal sea basins. Their presence over volcanic arcs or continental crusts requires a mechanism that can explain the emplacement of such dense ophiolitic material unto lighter material such as volcanic arcs or continental masses. Such mechanism operates in general in a convergent margin setting where the ophiolites ride over long and flat-lying thrust faults (nappes). In very minor and usually contestable circumstances, ophiolite presence along shear zones may also suggest a significant role by strike-slip movements This paper recounts several ophiolite emplacement mechanisms developed in recent years and modeled from various examples the world over. Particular attention is given to Philippine examples.
