Under lower mantle conditions, it is thought that the arrangement of electrons in carbonate minerals changes under the pressure stress in such a way that iron may be significantly redistributed.

Upper mantle carbonates are magnesium-rich and iron-poor. Under lower mantle conditions, it is thought that the arrangement of electrons in carbonate minerals changes under the pressure stress in ...

In the mid-19th Century, as the Industrial Revolution roared along in Britain, uncounted millions of cast-iron fireplace mantels in myriad styles rolled off production lines. There were floral desi… ...

The +0.1‰ elevated 56Fe/54Fe ratio of terrestrial basalts relative to chondrites was proposed to be a fingerprint of core-mantle segregation. However, the extent of iron isotopic fractionation ...

An accidental find shows how iron from Earth's core might be seeping into its mantle layer above, which could also help understand the internal structure of the planet Mercury.

Our readers’ submissions this month include a good Rookwood Pottery vase in their popular “vellum” glaze, a cast iron mantle clock that still keeps perfect time after a century of use, and a ...

Previous research had shown that upper mantle carbonates are magnesium-rich and iron-poor. Under lower mantle conditions, it is thought that the arrangement of electrons in carbonate minerals ...
