Variation of Lithosphere-Asthenosphere boundary beneath Iran by using S Receiver function
The current geological and tectonic setting of Iran is due to the ongoing convergence between the Arabian and Eurasian Plates, which resulted in the formation of the Iranian plateau, mountain building, extensive deformation and seismicity. The Iranian plateau is characterized by various domains including the continental collision and the oceanic plate seduction. Based on S receiver functions ar...
متن کاملNorth American lithospheric discontinuity structure imaged by Ps and Sp receiver functions
[1] Sp and Ps converted seismic waves at 93 permanent seismic stations are used to image upper mantle velocity discontinuities across the contiguous United States and portions of southeast Canada and northwest Mexico. Receiver functions are calculated with frequency‐ domain deconvolution and migrated with 1D models that account for variations in crustal structure and mantle velocities between s...
متن کاملContrasting lithospheric signatures across the western United States revealed by Sp receiver functions
a r t i c l e i n f o a b s t r a c t Keywords: receiver functions lithosphere lithosphere–asthenosphere boundary mid-lithospheric discontinuity To explore how lithospheric structure varies between tectonic and magmatic terranes of the western United States, we use observations of shear-to-compressional wave conversions across lithospheric velocity interfaces. With a newly developed automatic m...
متن کاملNew seismic imaging of some tectonic zones in the Iranian Plateau
The Iranian Plateau is characterized by diverse tectonic domains, including the continental collisions (e.g. the Zagros and Alborz Mountains) and oceanic plate subduction (e.g. Makransubduction zone). To derive a detailed image of the crust–mantle (Moho) and lithosphere–asthenosphere (LAB) boundaries in some tectonically units of the Iranian Plateau, we used a large number of S receiver functio...
متن کاملThe boundary between the Indian and Asian tectonic plates below Tibet.
The fate of the colliding Indian and Asian tectonic plates below the Tibetan high plateau may be visualized by, in addition to seismic tomography, mapping the deep seismic discontinuities, like the crust-mantle boundary (Moho), the lithosphere-asthenosphere boundary (LAB), or the discontinuities at 410 and 660 km depth. We herein present observations of seismic discontinuities with the P and S ...
