Recent Research

My research activity consists on imaging seismically the deep Earth interior, from the lithosphere to the lower mantle, and relate observed seismic heterogeneities to what we know about mineral physics, geodynamics and geochemistry. I currently focus on mantle seismic discontinuities, especially at 410 and 660 km depth in the mantle transition zone. My seismological tools are reflected (PcP and SS-precursors) and converted (P-S and S-P receiver functions) body-waves.

SS-precursors

P-to-s receiver functions

For a general explanation of what is a P-to-s (Pds) receiver function, follow this link (Charles J. Ammon webpage). The links below give an overview of my main results. You may also like to read my contribution to the MantlePlume website (2007) or have an extensive view of my Pds data set (2008).


Seismic evidence for a global low velocity layer within the Earth's upper mantle (Nature Geoscience, 2010).


The mantle transition zone as seen by global Pds phases: no clear evidence for a thin transition zone beneath hotspots (J. Geophys. Res., 2008). (pdf)
