Mineral compositions from numerous volcanic rocks that sample the mantle keel beneath Western Australia’s Kimberley Craton reveal the temperature and mineralogy that explain its long-lived stability.
Minerals formed in short-lived hydrothermal systems set off by a meteor impact in France preserved information about noble gases in the ancient atmosphere.
A new study investigates the dynamics of the complex continental collision that formed the European Alps and reveals how structural alignments change with depth.
A new method for examining the tiny vibrations of Earth caused by ocean swells could help reveal details of deep-Earth structure.
Computational models of the composition and volumes of magmas during continental rifting evolution provide clues on the heterogeneities of the deep melting mantle.
Ocean Drilling Program cores and helium isotopes put better constraints on the ocean circulation in the north Pacific.
A new book presents major advances in our understanding of core-mantle interaction and co-evolution, and showcases technological developments improving our insights into deep Earth processes.
A mysterious seismic feature at the bottom of Earth’s mantle is more widespread than previously thought.
Abyssal peridotites show through their isotopic composition a complex history. From differences we can infer the existence of ultra depleted mantle and an uneven contribution to ridge magmatism.
A new study demonstrates that robust anelastic attenuation measurements can be made across ocean bottom seismic arrays at different locations using surface wave array analysis.
