There is little doubt that densities for the Earth's outer core, inferred from seismology, require
that it is constituted of an alloy of liquid iron and light elements. However, the nature of the …

Recent seismological work has revealed new structures in the boundary layer between the
Earth's core and mantle that are altering and expanding perspectives of the role this region …

Enlarged and fully updated, this new edition takes into account the considerable
experimental and theoretical progress recently made in the field. Introduction to the Physics …

Unusual physical properties at the core-mantle boundary have been inferred from seismic
and geodetic observations in recent years. We show how both types of observations can be …

Electrical conductivity structures of the Earth's mantle estimated from the magnetotelluric and
geomagnetic deep sounding methods generally show increase of conductivity from 10− 4 …

The top of Earth's liquid outer core is nearly 2900 km beneath Earth's surface, so we will
never be able to observe it directly. This hot, dense, molten iron‐rich body is continuously in …

The electrical conductivity of Earth's mantle has recently become an interesting topic across
diverse Earth science communities. Many electrical conductivity data of mantle phases have …

Recent laboratory measurements of electrical conductivity of mantle minerals are used in
forward calculations for mantle conditions of temperature and pressure. The electrical …

Geophysical models show that electrical conductivity in Earth's mantle rises about two
orders of magnitude through the transition zone in the depth range 410 to 660 kilometers …

We have extended our geodynamo simulation 40 000 years using a more realistic
representation of the thermodynamics and convection. The anelastic approximation …
