Introduction [2] The Tonga-Lau region is a compact microcosm of plate tectonics, containing zones of lithospheric subduction, island arc building, and oceanic crustal formation ().The Pacific Plate subducts beneath the Indo-Australian plate at the Tonga Trench, and melt is believed to rise from the subducting slab to form the volcanic Tonga Ridge. Answer and Explanation: No, ocean trenches do not occur at divergent plate boundaries. 2. This book provides the first comprehensive overview of a complete subduction orogen, the Andes. To date the results provide the densest and most highly resolved geophysical image of an active subduction orogen. The greatest ocean depth measured is in the Challenger Deep of the Mariana Trench, at a depth of 11,034 m (36,201 ft) below sea level. It is centered at approximately 19° S. latitude and 173° E. longitude. Use the map legend to figure out what the colors represent. This book brings together seventeen papers that are dedicated to the investigation of the tectonic processes that take place during arc-continent collision. The Tonga Trench is formed at an oceanic vs. oceanic plate boundary, where the denser oceanic plate is subducted under the other oceanic plate. Plate boundaries. Accretionary complexes are typically made up of a mix of turbidites of terrestrial material, basalts from the ocean floor, and pelagic and hemipelagic sediments. So, we can see that Trenches are generally parallel to a volcanic island arc. The Tonga trench is the crustal boundary between which two tectonic plates? Found insideThis unique book presents an overview of isostasy for graduate students and researchers in geoscience. Shading indicates areas deeper than 7000 m. Map was created from a 200-m Sea Beam 2000 grid (Boomerang 8 and Westward 12). I find that this region is associated with distinct groups of earthquakes whose mechanisms document tearing of the Pacific Plate lithosphere, back-arc extension in the northern Lau Basin, strike-slip faulting along the Fiji Fracture Zone, and bending and underthrusting of the Pacific Plate at the Tonga trench.
