Violent collisions between the growing Earth and other objects in the solar system generated significant amounts of iron vapor, according to a new study by LLNL scientist Richard Kraus and colleagues.

New research has identified a new restriction on the chemistry involved in the Earth’s core, explaining how it was able to crystallize millions of years ago. According to this work, the core would ...

A new technique provides fresh insight into the process by which the materials that formed Earth's core descended into the depths of our planet, leaving behind geochemical traces that have long ...

Final formation of the core itself could have occurred through diapirism, whereby the dense molten iron forced through the underlying solid mantle. Rudge and colleagues 1 present numerical models, ...

An international collaboration including researchers from Lawrence Livermore National Laboratory has discovered that the Earth’s core formed under more oxidizing condition’s than previously proposed.

Late addition of meteoric material to the Earth's mantle could explain the presence of iron-loving elements that should have entered the Earth's core at its formation. But experiments at realistic ...

Researchers investigate the effects of oxygen content on the melting of mantle rocks and the formation of early Earth magma It is widely accepted that the early Earth largely consisted of molten magma ...

Researchers have long struggled to explain how Earth’s solid inner core formed, cooled, and crystallized without undergoing extreme supercooling. But a recent study published in Nature ...

Inner core formation is not just a matter of determining when the core cooled to its freezing point, but instead involves the process of crystallization which depends on its exact chemical composition ...

Washington, DC—A new technique developed by Carnegie’s Yingwei Fei and Lin Wang provides fresh insight into the process by which the materials that formed Earth’s core descended into the depths of our ...

Russell has a PhD in the history of medicine, violence, and colonialism. His research has explored topics including ethics, science governance, and medical involvement in violent contexts. Russell has ...
