Sassolite Precipitation at the Restless Campi Flegrei Volcano in Italy Points to Hydrothermal Flashing by Deep Boron‐Rich Brines

Journal of Geophysical Research: Solid Earth, Volume 130, Issue 10, October 2025.
Abstract Studying the behavior of dormant volcanoes is a major challenge in volcanology. Here, we conducted a 10‐year survey of hydrothermal mineralization at Campi Flegrei, an active volcano near Naples in Italy, which last erupted in 1538. Our survey revealed a significant output of boric acid at the hydrothermal sulfate discharge area of Pisciarelli,

Gravimetric and morpho-structural analyses in the superhot geothermal system Los Humeros: an example from central Mexico

Geothermal Energy
The influence of deep and regional geological structures is becoming increasingly important in superhot geothermal systems due to their proximity to the transition between brittleness and ductility.
