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 …

The Urey ratio describes the contribution of internal heat production to planetary‐scale
energy balance, and knowing this thermal budget for Earth is essential to understand its …

Earth's global magnetic field arises from vigorous convection within the liquid outer core.
Palaeomagnetic evidence reveals that the geodynamo has operated for at least 3.4 billion …

The terrestrial planets are depleted in volatile elements with respect to chondritic meteorites,
their possible building blocks. However, the timing, extent and origin of volatile depletion is …

The abundance of K in the silicate Earth provides control on the composition of the Earth's
interior, the dominant mode of mantle convection, the thermal evolution of the planet, and …

We measure the electrical resistivity of hcp iron up to∼ 170 GPa and∼ 3000 K using a four-
probe van der Pauw method coupled with homogeneous flattop laser heating in a DAC, and …

Meteorites record processes that occurred before and during the formation of the Solar
System in the form of nucleosynthetic anomalies: isotopic compositions that differ from the …

Stable potassium isotopes are one of the emerging non-traditional isotope systems enabled
in recent years by the advance of Multi-Collector Inductively-Coupled-Plasma Mass …

We present the results of new partitioning experiments between metal and silicate melts for
a series of elements normally regarded as refractory lithophile and moderately siderophile …

Data returned from the gamma‐ray spectrometer onboard the Mercury Surface, Space
Environment, Geochemistry, and Ranging (MESSENGER) spacecraft have been interpreted …
