28 Investigating Upper Mantle Discontinuities Beneath Subduction Zones

چکیده
Subduction zones can be regarded as natural laboratories because of the wide variety of processes involved. Macquarie Island is an exposed portion of the Macquarie Ridge, and is located where the Australian plate meets the Pacific plate. To its north is the Tonga trench, where the old Pacific floor subducts at a rapid rate below the Indo-Australia plate, producing a deep slab of former oceanic lithosphere.

Frequency-dependent shear wave splitting beneath the Japan and Izu-Bonin subduction zones
Despite its importance for ourunderstandingof physical processes associatedwith subduction, the geometry of mantle flow in subduction zones remains poorly understood, particularly in the mantle wedge above subducting slabs. Constraints onmantle flowanddeformation canbeobtainedbymeasurements of shearwave splitting, a valuable tool used to characterize the geometry and strength of seismic anisotr...
متن کاملSeismic images of crust and upper mantle beneath Tibet: evidence for Eurasian plate subduction.
Seismic data from central Tibet have been combined to image the subsurface structure and understand the evolution of the collision of India and Eurasia. The 410- and 660-kilometer mantle discontinuities are sharply defined, implying a lack of a subducting slab beneath the plateau. The discontinuities appear slightly deeper beneath northern Tibet, implying that the average temperature of the man...
متن کاملImaging the seismic structure of the crust and upper mantle beneath the Great Plains, Rio Grande Rift, and Colorado Plateau using receiver functions
[1] The seismic structure of the crust and upper mantle of the southwestern United States is examined using receiver functions calculated from teleseismic arrivals recorded in the Colorado Plateau–Rio Grande Rift–Great Plains Seismic Transect (LA RISTRA) experiment. We apply receiver function estimation and filtering methods developed by Wilson and Aster (2005) to produce receiver functions wit...
متن کاملAnisotropy and Flow in Pacific Subduction Zone Back-arcs
We have obtained constraints on the strength and orientation of anisotropy in the mantle beneath the Tonga, southern Kuril, Japan, and Izu-Bonin subduction zones using shear-wave splitting in S phases from local earthquakes and in teleseismic core phases such as SKS. The observed splitting in all four subduction zones is consistent with a model in which the lower transition zone (520–660 km) an...
متن کاملHigh-resolution models of subduction zones: Implications for mineral dehydration reactions and the transport of water into the deep mantle
[1] Arc volcanism is intimately linked to mineral dehydration reactions in the subducting oceanic mantle, crust, and sediments. The location of slab dehydration reactions depends strongly on the temperature and pressure conditions at the top of the subducting plate and hence on the detailed thermal structure of subduction zones. A particularly important physical property of subduction zone ther...
