Early Archaean onset of volatile cycling at subduction zones

G. Caro, T. Grocolas, P. Bourgeois, P. Bouilhol, S. J. Mojzsis, G. Paris. Nature Geoscience volume 18, pages 436–442 (2025) Voir en ligne : https://doi.org/10.1038/s41561-025-01677-5 Abstract: The subduction of pelagic sediments and altered oceanic crust modulates the global cycle of volatile elements. Sulfate and carbonate fluids released when one plate descends beneath another modify the

Advances in Igneous Petrology: Coupling Chemical Maps with Thermodynamic Models to Tackle Mush Crystallization Dynamics and Crystal–Melt Segregation

Lydéric France , Valentine Charvet , Aurore Toussaint Journal of Petrology, Volume 66, Issue 5, May 2025, egaf044 Voir en ligne : https://doi.org/10.1093/petrology/egaf044 Abstract: Chemical maps of igneous samples contain prodigious information constraining the evolution and solidification of magmas and mushy systems. Nevertheless, their full potential remains unrealized; they are mostly used only to highlight
