High Resolution Imaging of Seismic Velocity Discontinuities:

$Synthetic experiments with migration seismic processing of receiver functions. (a) Model containing regional 220 km discontinuity, a flat 410 km discontinuity with a small gap, and an undulating 660 km discontinuity. Synthetic seismograms are generated using the same source and receiver geometries as in the Snake River Plain PASSCAL experiment. (b) Common midpoint stack of synthetic receiver functions. Focusing and diffraction artifacts are obvious. (c) Backprojection migration of synthetic receiver functions. The starting model is recovered well, including the gap in the 410 km discontinuity and the large undulation on the 660 km discontinuity.$
