Constraining the core's composition is essential for understanding Earth accretion, core
formation and the sustainment of Earth's magnetic field. Earth's outer and inner core exhibit …

Earth's inner core (IC) is less dense than pure iron, indicating the existence of light elements
within it. Silicon, sulfur, carbon, oxygen and hydrogen have been suggested to be the …

We review some issues relevant to volatile element chemistry during accretion of the Earth
with an emphasis on historical development of ideas during the past century and on issues …

The Earth's core is composed mainly of iron. Since the liquid core coexists with solid at the
inner core boundary (ICB), the melting point of iron at 330 GPa offers a key constraint on …

Seismic studies have found fine-scale anomalies at the core–mantle boundary (CMB), such
as ultralow velocity zones (ULVZs), and the core rigidity zone,. ULVZs have been attributed …

The diamond anvil cell (DAC) technique combined with laser heating is one of the major
methods for studying materials at high pressure and high temperature conditions. In this …

As the main constituent of planetary cores, pure iron phase diagram under high pressure
and temperature is of fundamental importance in geophysics and planetary science …

Mercury's metallic core is expected to have formed under highly reducing conditions,
resulting in the presence of significant quantities of silicon alloyed to iron. Here we present …

The melting line of cobalt has been investigated both experimentally, using synchrotron X-
ray diffraction coupled with laser-heated diamond anvil cells, and theoretically, using ab …

Melting experiments were performed on the Fe‐C‐H system to 127 GPa in a laser‐heated
diamond anvil cell. On the basis of in situ and ex situ sample characterizations, we found …
