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 …

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 …

Earth as an Evolving Planetary System, Fourth Edition discusses key topics dealing with the
evolution and interaction through time of Earth's crust, mantle, core, atmosphere …

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 …

Earth's core is likely the largest reservoir of carbon (C) in the planet, but its C abundance has
been poorly constrained because measurements of carbon's preference for core versus …

Pebbles of millimeter sizes are abundant in protoplanetary discs around young stars.
Chondrules inside primitive meteorites—formed by melting of dust aggregate pebbles or in …

Geophysical and geochemical evidence suggests that Earth's core is predominantly made of
iron (or iron-nickel alloy) with several percent of light elements. However, Earth's solid inner …

Geophysical and cosmochemical constraints suggest the inner-core is mainly composed of
iron with a few percent of light elements. However, despite extensive studies over many …

Oxygen and iron are the most abundant elements on Earth, and their compounds are key
planet-forming components. While oxygen is pervasive in the mantle, its presence in the …

Melting of carbonated eclogite or peridotite in the mantle influences the Earth's deep volatile
cycles and bears on the long-term evolution of the atmosphere. Existing data on the melting …
