Microbial Sulfur Isotope Fractionation in the Chicxulub Hydrothermal System. [PDF]

Astrobiology, 2021
Target lithologies and post-impact hydrothermal mineral assemblages in a new 1.3 km deep core from the peak ring of the Chicxulub impact crater indicate sulfate reduction was a potential energy source for a microbial ecosystem (Kring et al., 2020).

Probing the hydrothermal system of the Chicxulub impact crater. [PDF]

Sci Adv, 2020
The Chicxulub impact event generated a long-duration hydrothermal system suitable for microbial life. The ~180-km-diameter Chicxulub peak-ring crater and ~240-km multiring basin, produced by the impact that terminated the Cretaceous, is the largest ...

A Polyextreme Hydrothermal System Controlled by Iron: The Case of Dallol at the Afar Triangle. [PDF]

ACS Earth Space Chem, 2019
One of the latest volcanic features of the Erta Ale range at the Afar Triangle (NE Ethiopia) has created a polyextreme hydrothermal system located at the Danakil depression on top of a protovolcano known as the dome of Dallol.

Caldera unrest driven by CO₂-induced drying of the deep hydrothermal system. [PDF]

Sci Rep, 2018
Interpreting volcanic unrest is a highly challenging and non-unique problem at calderas, since large hydrothermal systems may either hide or amplify the dynamics of buried magma(s). Here we use the exceptional ground displacement and geochemical datasets

Lithium isotope traces magmatic fluid in a seafloor hydrothermal system. [PDF]

Sci Rep, 2015
Lithium isotopic compositions of fluid inclusions and hosted gangue quartz from a giant volcanogenic massive sulfide deposit in China provide robust evidence for inputting of magmatic fluids into a Triassic submarine hydrothermal system. The δ7Li results

A GIS-Based Hydrogeological Approach to the Assessment of the Groundwater Circulation in the Ischia Volcanic Island (Italy)

Frontiers in Earth Science, 2022
Assessing the variations in space and time of groundwater circulation in volcanic islands is of paramount importance to the description of the hydro-geo-thermal system and implementation of hydrogeological, geochemical, and volcanic monitoring systems ...
