High resolution image of uppermost mantle beneath NE Iran continental collision zone

open access: yes, 2012
We invert 3775 relative P wave arrival times using the ACH damped least square method of Aki et al. (1977) to study upper mantle structure beneath the NE Iran continental collision zone.

Crustal and uppermost mantle shear-wave velocity structure beneath the Northeastern Iranian Plateau using an analysis of receiver function and surface‑wave tomography [PDF]

open access: yes
In this study, we investigate the crustal velocity structure and Moho discontinuity depth beneath the NE Iran continental collision zone through joint inversion of P receiver function and Rayleigh wave group velocity dispersion curves.

The deep structure of the Iranian Plateau [PDF]

open access: yes, 2015
High resolution structures of the lithosphere–asthenosphere system beneath a seismic profile in Iran are obtained by the simultaneous inversion of data from receiver functions and fundamental mode Rayleigh wave group velocity and validated by modeling ...
