backarc basin


فارسی

1 زمین‌شناسی و معدن:: حوضه پس کمان

Island arcs are separated from adjacent conti- nents by a marine basin underlain by ocean crust, the backarc basin (Figs. 7.2, 7.3). The resulting separation behind the island arc generates a backarc basin and with sufficient extension, new oceanic crust may form (example: Sea of Japan). The garland- or drape-like alignment of the island arcs results from their separation from the continent and the formation of backarc basins. Because the Mariana Arc comprises an intra-oceanic subduction zone, the formation of the backarc basin occurred solely within oceanic crust (Fig. 7.2). A curious situation at subduction zones with backarc basins (Mariana-type subduction) is the juxtaposition of strong convergence and divergence.
