Compositional heterogeneity near the base of the mantle transition zone beneath Hawaii

Seismic discontinuities near 410 and 660 km depth have often been used to map lateral variations in mantle temperature. Here, the authors apply array analysis to SS reflections off these discontinuities under Hawaii and find evidence of lateral variations in mantle composition at 660 km, but not at...

Sumario:Seismic discontinuities near 410 and 660 km depth have often been used to map lateral variations in mantle temperature. Here, the authors apply array analysis to SS reflections off these discontinuities under Hawaii and find evidence of lateral variations in mantle composition at 660 km, but not at 410 km.
