3-d s-velocity structure of upper mantle and moho depth variations in the makran subduction zone
the makran subduction zone in southeastern iran and southern pakistan is where the oceanic crust of the arabian plate (oman sea) is subducting beneath eurasia. compared to other subduction zones in the world, the makran subduction zone has some unusual features, including different seismicity patterns in its eastern and western parts. also, the quaternary volcanoes in the eastern part of makran...
متن کاملMineralogy and Composition of the Upper Mantle
Seismic velocities are calculated for two petrological models of the upper mantle, an olivine-rich assemblage, pyrolite, and a garnet-clinopyroxene rich, olivine bearing, assemblage, piclogite. These are compared with recent seismic profiles for various tectonic provinces. The .shield data is most consistent with a cold olivine and orthopyroxene-rich LID (the seismic lithosphere) extending to 1...
متن کاملBeneath Yellowstone: Evaluating Plume and Nonplume Models Using Teleseismic Images of the Upper Mantle
The Yellowstone hotspot commonly is thought to result from a stationary mantle plume rooted in the lower mantle over which North America moves. Yet Yellowstone’s initiation and its association with the “backward” propagating Newberry hotspot across eastern Oregon pose difficult questions to those explaining Yellowstone as a simple consequence of a deep-seated plume. Teleseismic investigations a...
