This paper provides the state-of-the-art discussion of major aspects of the composition and
evolution of the Earth's core. A comparison of experimentally-derived density of Fe with …

This review systematically presents all finds of geogenic, impact-induced, and
extraterrestrial iron silicide minerals known at the end of 2021. The respective morphological …

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 Earth's core is comprised mostly of iron and nickel, but it also contains several weight
percent of one or more unknown light elements, which may include silicon. Therefore it is …

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 …

We performed laser-heated diamond anvil cell experiments on bulk compositions in the
systems MgO–SiO 2–H 2 O (MSH) and MgO–Al 2 O 3–SiO 2–H 2 O (MASH) that constrain …

Earth's core is an iron‐rich alloy containing several weight percent of light element (s),
possibly including silicon. Therefore, the high pressure‐temperature equations of state of …

The melting curve of Ni has been determined to 125 GPa using laser-heated diamond anvil
cell (LH-DAC) experiments in which two melting criteria were used: firstly, the appearance of …

The Earth was formed by the accretion of both differentiated and undifferentiated parent
bodies, and the large density difference between metallic and ionic components gave rise to …

While hydrogen could be an important light alloying element in planetary iron cores, phase
relations in the Fe‐FeH system remain largely unknown at high pressures and temperatures …
