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 …

The composition and state of Earth's core, located deeper than 2,900 km from the surface,
remain largely uncertain. Recent static experiments on iron and alloys performed up to inner …

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 …

Topics involved in studies of the Earth's magnetic field and its secular variation range from
the intricate observations of geomagnetism, to worldwide studies of archeomagnetism and …

This is the third paper in a four‐part sequence that examines the nature of mantle layering
using the multiple‐ScS phases and internal reflections observed within the reverberative …

Carbon is extremely abundant in the solar system (10× Si, 20× S) in Cl carbonaceous
chondrites (3.2 wt%) and it dissolves readily in liquid Fe at low pressures (4.3 wt% at 1420 …

Laboratory experiments document that liquid iron reacts chemically with silicates at high
pressures (≥ 2.4× 1010 Pascals) and temperatures. In particular,(Mg, Fe) SiO3 perovskite …

Magnesium oxide (MgO) is representative of the rocky materials comprising the mantles of
terrestrial planets, such that its properties at high temperatures and pressures reflect the …

In situ synchrotron x-ray diffraction measurements of FeO at high pressures and high
temperatures revealed that the high-pressure phase of FeO has the NiAs structure (B8). The …

Maps of the fluid flow at the core surface are important for a number of reasons: foremost
they may provide some insight into the workings of the geodynamo and may place useful …
