A New Origin Story for Mars’s Burns Formation

by Morgan Rehnberg 3 May 20233 May 2023

The Red Planet’s Grasberg and Burns formations have different compositions today, but they may have started out the same way.

Transmission electron microscope images of diverse synthetic hematite grains were used to explain key domain state and anisotropy signals in first-order reversal curve (FORC) diagrams.

Is Earth’s Core Rusting?

by Jiuhua Chen and Shanece S. Esdaille 25 April 20223 January 2023

If subduction carries hydrous minerals deep into Earth’s mantle, they may “rust” the iron outer core, forming vast sinks of oxygen that can later be returned to the atmosphere.
