Global observations of reflectors in the mid-mantle with implications for mantle structure and dynamics

Waszek, Lauren; Schmerr, Nicholas C; Ballmer, Maxim D


Seismic tomography indicates that flow is commonly deflected in the mid-mantle. However, without a candidate mineral phase change, causative mechanisms remain controversial. Deflection of flow has been linked to radial changes in viscosity and/or composition, but a lack of global observations precludes comprehensive tests by seismically detectable features. Here we perform a systematic global-scale interrogation of mid-mantle seismic reflectors with lateral size 500–2000 km and depths...[Show more]
