Palagonitization of Volcanic Rocks in Polar Climates: The Case of Deception Island (Antarctica)

Geochemistry, Geophysics, Geosystems, Volume 26, Issue 12, December 2025.
Abstract A detailed study of palagonitization in rocks from Deception Island—one of Antarctica's most active volcanoes—has been performed to advance our understanding of this alteration process. A detailed petrographic (optical and SEM), mineralogical (XRD), and mineral and glass spot geochemistry (EDS and EMP) characterization has been conducted on ...
