Alteration's Control on Frictional Behavior and the Depth of the Ductile Shear Zone in Geothermal Reservoirs in Volcanic Arcs

open access: yesJournal of Geophysical Research: Solid Earth, Volume 130, Issue 2, February 2025.
Abstract The majority of geothermal energy is produced in tectonically active volcanic‐arc regions due to their high geothermal gradients. Reservoirs in these settings are often stratified with smectite/kaolinite‐, illite‐, and chlorite‐rich zones, in order of increasing depth and temperature. Eighteen andesitic core and surface samples were taken from

Radiogenic Strontium‐ and Uranium‐Isotope Tracers of Water‐Rock Interactions and Hydrothermal Flow in the Upper Geyser Basin, Yellowstone Plateau Volcanic Field, USA

open access: yesGeochemistry, Geophysics, Geosystems, Volume 25, Issue 10, October 2024.
Abstract Natural radiogenic isotopes (primarily 87Sr/86Sr) from hot springs in the Upper Geyser Basin of the Yellowstone Plateau volcanic field and associated rocks were used to evaluate groundwater flow patterns, water‐rock reactions, and the extent of mixing between various groundwater sources.

Glacial and volcanic landforms in the upper catchment of Claro River, Central Chile (35.5°S): A Late Quaternary geomorphological case study

open access: yesEarth Surface Processes and Landforms, Volume 49, Issue 7, Page 2291-2307, 15 June 2024.
The upper catchment of the Claro river in the central Chilean Andes is described in terms of volcanic and glacial landforms seeking to establish a relative chronology associated to events during the late Pleistocene and Holocene, which is summarized in seven phases and presented as a conceptual model.

Alteration of the tree–soil microbial system triggers a feedback loop that boosts holm oak decline

open access: yesFunctional Ecology, Volume 38, Issue 2, Page 374-390, February 2024.
Read the free Plain Language Summary for this article on the Journal blog. Abstract In anthropic savanna ecosystems from the Iberian Peninsula (i.e. dehesa), complex interactions between climate change, pathogen outbreaks and human land use are presumed to be behind the observed increase in holm oak decline.

Hydrothermal Signatures Discovered in Outcropping Rocks of the Los Humeros Geothermal Field (Mexico): A Geochemometric Exploration Case Study

open access: yesGeofluids, Volume 2024, Issue 1, 2024.
Hydrothermal geochemical signatures in outcropping rock samples of the super‐hot Los Humeros geothermal field were discovered by using an integrated geochemometric study of the mobility of components (major oxides) and trace elements. Chemical component and element mobilities were determined by using the Gresens–Grant equation for mass balances.

The Use of Bromeliads as Biomonitors of Air Quality: A Global Review

open access: yesInternational Journal of Forestry Research, Volume 2024, Issue 1, 2024.
Air pollution is a global problem in urban and rural areas, mainly related to vehicular traffic and industrial activities. Bromeliads have been widely used globally for active and passive air quality monitoring. However, a systematic review to facilitate the access and analysis of this information is yet to be made available. The objective of this work
