    Hot mantle transition zone beneath Iceland and the adjacent Mid-Atlantic Ridge inferred from P-to-S conversions at the 410- and 660-km discontinuities 
    Shen, Yang; Solomon, Sean C.; Bjarnason, Ingi Þorleifur; Purdy, G. M. (American Geophysical Union (AGU), 1996-12-01)
    P‐to‐S conversions from the two primary discontinuities near 410 and 660 km depth (P410s and P660s phases) are evident in particle motions and receiver functions of teleseismic body waves recorded by broadband seismic stations in Iceland. The average ...

    Seismic evidence for a lower-mantle origin of the Iceland plume 
    Shen, Yang; Solomon, Sean C.; Bjarnason, Ingi Þorleifur; Wolfe, Cecily J. (Springer Nature, 1998-09)
    Iceland, one of the most thoroughly investigated hotspots1,2,3, is generally accepted to be the manifestation of an upwelling mantle plume4. Yet whether the plume originates from the lower mantle or from a convective instability at a thermal boundary ...

    Seismic evidence for a tilted mantle plume and north–south mantle flow beneath Iceland 
    Shen, Yang; Solomon, Sean C.; Bjarnason, Ingi Þorleifur; Nolet, Guust; Morgan, W.Jason; Allen, Richard M.; Vogfjörð, Kristín; Jakobsdóttir, Steinunn; Stefánsson, Ragnar; Julian, B.R.; Foulger, G.R. (Elsevier BV, 2002-04)
    Shear waves converted from compressional waves at mantle discontinuities near 410- and 660-km depth recorded by two broadband seismic experiments in Iceland reveal that the center of an area of anomalously thin mantle transition zone lies at least 100 ...
