Rift-to-Ridge: Mid-Atlantic Ridge Segments Imprinted During Rifting

by Emilie Hooft 19 October 202317 October 2023

A new seismic study shows that magmatism along the eastern North American rift margin was segmented, and that rift discontinuities influence formation of fracture zones along the Mid-Atlantic Ridge.

Uncovering Mantle Heterogeneities Beneath Drifting Continents

by Fabio A. Capitanio 11 September 20236 September 2023

Computational models of the composition and volumes of magmas during continental rifting evolution provide clues on the heterogeneities of the deep melting mantle.

Third Time’s the Charm for Iceland’s Fagradalsfjall

Katherine Kornei, Science Writer by Katherine Kornei 19 July 202331 July 2023

The volcanic region, which erupted in both 2021 and 2022 after more than 7 centuries of dormancy, is at it again.

This snapshot of a new global mantle convection model depicts Earth 180 million years ago, with broad mantle upwellings (in copper) equal to or greater than 1 kelvin meter per year, reconstructed continental blocks (gray polygons), and kimberlite eruptions (magenta columns).

Deciphering the History of a Rock’s Crystallization

by Nikolai Bagdassarov 26 June 202322 June 2023

By combining a phase field function approach with bulk thermodynamics of mineral phases, the thermal history of a rock can now be deciphered from its distribution of mineral phases.

Earth Is Noisy. Why Should Its Data Be Silent?

by Leif Karlstrom, Ben Holtzman, Anna Barth, Josh Crozier and Arthur Paté 9 June 20236 June 2024

Combining visual and sonic representations of data can make science more accessible and help reveal subtle details. The recent decade-long eruption of Hawaii’s Kīlauea Volcano offers a prime example.
