Interaction of Cocos and Rivera plates with the upper-mantle transition zone underneath central Mexico
Mantle processes Phase transitions North America
2014/4/10
Receiver functions (RFs) from 224 permanent and temporary stations in central and southern Mexico were used to characterize the upper-mantle transition zone in that region. Discontinuities at 410 and ...
Generation of talc in the mantle wedge and its role in subduction dynamics in central Mexico
Subduction talc serpentine receiver function mantle wedge P-to-S velocity ratio
