Thermodynamic Constraints on H2 Production and Habitability From Mg‐Rich Serpentinites as Mars Analogs

Journal of Geophysical Research: Planets, Volume 131, Issue 5, May 2026.
Abstract Serpentinization produces hydrogen and methane through abiotic water‐rock interactions, potentially supporting chemotrophic life in planetary subsurface environments. Serpentine deposits in the Martian Noachian landscapes of Nili Fossae and the Southern Highlands have been considered as potential paleo‐habitable zones. However, the geochemical

The Influence of Water Temperature on the Hydrogeochemical Composition of Groundwater during Water Extraction and Reinjection with Geothermal Heat

Energies, 2023
This study presents a simulation of potential changes in groundwater in three wells within a Quaternary gravel aquifer in the city of Ljubljana when groundwater cooled by about 4 °C is reinjected into it.

Leveraging the TabPFN Algorithm for High‐Resolution Mapping of Groundwater Bicarbonate and Its Scaling Risk Across China

Water Resources Research, Volume 62, Issue 5, May 2026.
Abstract Large‐scale groundwater quality prediction is often constrained by sparse sampling, limiting the reliability of spatial assessments. This study introduces Tabular Prior‐data Fitted Network (TabPFN), a machine learning model based on prior‐fitting networks, to address this challenge and enable high‐precision mapping of groundwater bicarbonate ...

Geochemical Features of the Thermal and Mineral Waters From the Apuseni Mountains (Romania)

Frontiers in Earth Science, 2021
The Apuseni Mountains are located between the large geothermal area of the Pannonian Basin and the low thermal flux Transylvanian Basin. Thermal and mineral waters have been sampled from 42 points along a NW-SE transect.

Spatiotemporal Patterns of Nutrient Fluxes in an Agricultural Reservoir

JAWRA Journal of the American Water Resources Association, Volume 62, Issue 2, April 2026.
ABSTRACT Reservoirs are vital tools for managing riverine water resources but also influence water quality through in‐lake nutrient (i.e., nitrogen [N] and phosphorus [P]) dynamics that affect downstream ecosystems. This study presents a multiscale spatiotemporal characterization of water quality in Carlyle Lake, an agriculturally impacted reservoir in

Chemical stimulation of geothermal reservoirs using retarded acid systems: current developments and potential directions

Geothermal Energy
Stimulation techniques to enhance fluid pathways are an important tool to make geothermal projects economically feasible. So far, hydraulic stimulation is used almost exclusively for reservoir-wide improvement of the permeability, but induced seismicity ...

Hydrochemical Characteristics of High‐Temperature Geothermal Fluids and Quantitative Assessment of Wellbore Scaling in the Yangbajain Geothermal Field, Tibet

Geofluids, Volume 2026, Issue 1, 2026.
Severe calcium carbonate scaling occurs in the wellbores of high‐temperature geothermal wells in the Yangbajain Geothermal Field. Based on sampling and laboratory analysis of the geothermal field, this study investigates the hydrogeochemical characteristics of the geothermal fluids, estimates the reservoir temperature, and reconstructs the bottom‐hole ...

Contrasting controls on hydrogeochemistry of arsenic-enriched groundwater in the homologous tectonic settings of Andean and Himalayan basin aquifers, Latin America and South Asia

, 2019
High groundwater arsenic (As) across the globe has been one of the most well researched environmental concerns during the last two decades. Consequently, a large scientific knowledge-base has been developed on As distributions from local to global scales.
