Continent-sized anomalous zones with low seismic velocity at the base of Earth's mantle
Seismic images of Earth's interior reveal two massive anomalous zones at the base of the
mantle, above the core, where seismic waves travel slowly. The mantle materials that …

Globally distributed subducted materials along the Earth's core-mantle boundary: Implications for ultralow velocity zones
Ultralow velocity zones (ULVZs) are the most anomalous structures within the Earth's
interior; however, given the wide range of associated characteristics (thickness and …

The high conductivity of iron and thermal evolution of the Earth's core
We measured the electrical resistivity of iron and iron-silicon alloy to 100 GPa. The resistivity
of iron was also calculated to core pressures. Combined with the first geophysical model …
