Imaging Lithospheric Discontinuities Beneath the Northern East African Rift Using S -to-P Receiver Functions

Receiver Function Imaging of Mantle Transition Zone Discontinuities Beneath the Tanzania Craton and Adjacent Segments of the East African Rift System

The mantle transition zone (MTZ) discontinuities beneath the Tanzania Craton and the Eastern and Western Branches of the East African Rift System are imaged by stacking over 7,100 receiver functions. The mean thickness of the MTZ beneath the Western Branch and Tanzania Craton is about 252 km, which is comparable to the global average and is inconsistent with the existence of present-day thermal...

Imaging mantle discontinuities using multiply-reflected P-to-S conversions

a r t i c l e i n f o a b s t r a c t Improving the reliability and accuracy in the determination of the depth to velocity discontinuities in the Earth's mantle is essential for a better understanding of mantle dynamics, as well as for addressing such fundamental questions as the origin of mantle plumes and fate of subducted slabs. Most existing techniques that utilize receiver function stackin...

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...
