New Mechanism for “Giant” Greigite Growth in Deep-Sea Sediments

by Agnes Kontny 2 December 202229 November 2022

Understanding greigite formation pathways in sediments is a prerequisite for assessing the marine iron-sulfur-carbon cycle and yield reliable near-syn-sedimentary paleomagnetic records.

Tracing Oxidizing Slab Fluids in Cold Volcanic Arcs

by Susanne Straub 28 October 202215 November 2022

Elevated copper isotope ratios in arc magmas from fluid-rich cold subduction zones support the role of oxidizing fluids from the subducted lithospheric serpentinite in the oxidization of arc magmas.

Why is the North China Craton Vulnerable to Destruction?

by Sujoy Ghosh 20 October 202218 October 2022

A new study suggests that carbonatite metasomatism, not silicate metasomatism as previously thought, was dominant prior to the removal of the North China Craton in the early Cretaceous.

Modeling Groundwater Responses to Earth Tides

by Beatriz Quintal 19 October 202217 October 2022

Tidal fluctuations in water well levels can reveal characteristics of the subsurface, and a new model based on coupled physics delineates the limitations of inherently simplistic analytical solutions.
