Metastable mantle phase transformations and deep earthquakes in subducting oceanic lithosphere

SH Kirby, S Stein, EA Okal, DC Rubie - Reviews of geophysics, 1996 - Wiley Online Library

Effects of relative plate motion on the deep structure and penetration depth of slabs below the Izu-Bonin and Mariana island arcs

R van der Hilst, T Seno - Earth and Planetary Science Letters, 1993 - Elsevier
An increasing number of seismological studies indicate that slabs of subducted lithosphere
penetrate the Earth's lower mantle below some island arcs but are deflected, or, rather, laid …

Geologic implication of the whole mantle P-wave tomography.

深尾良夫, 丸山茂徳, 大林政行, 井上公 - 地質学雑誌, 1994 - jlc.jst.go.jp
