Special Issue Information
Dear Colleagues,
Geological fluids are pervasive crustal components consisting of groundwater, hydrothermal fluids, gas-phase fluids, and dissolved ionic substances, which participate in the entire process of crustal tectonic evolution, material cycling, and energy transfer. Active fault systems serve as critical migration channels and dynamic boundaries for crustal fluids and geothermal heat. Deep fluid circulation, material exchange, and thermal state variations within fault zones are closely coupled with regional tectonic stress accumulation, fault creeping, and seismogenic processes. Hydrogeochemical and geothermal anomalies observed in hot springs and groundwater systems are widely recognized as seismic precursors for tracking earthquake activity and evaluating seismic risks.
Researchers have made significant advances in fault-fluid geochemistry and thermal regime monitoring. Nevertheless, scientific gaps still exist, e.g., the detailed mechanisms governing fluid migration within deep fault systems, the quantitative relationship between fluid geochemical anomalies and changes in tectonic stress, the challenge of distinguishing potential geo-fluid concentration anomalies from interference of hydrological or meteorological origin, and the establishment of integrated frameworks that combine field observation with laboratory analysis for seismic fluid tracking related to geo-fluid activity.
To advance our understanding of seismogenesis and earthquake forecasting related to geo-fluid activity, this Special Issue welcomes submissions of original research, methodological advances, and comprehensive reviews that delve into fault-zone fluid dynamics, thermodynamic processes, and their geochemical responses.
This Special Issue will welcome manuscripts that link the following themes:
- Migration, circulation, and dynamic evolution mechanisms of subsurface and geothermal fluids in active fault zones
- Hydrogeochemical, gas geochemical, and isotopic tracing of deep fault fluid activities
- Identification, verification, and discrimination methods of seismic fluid precursors and interference
We look forward to receiving your original research articles and reviews.

Manuscript Submission Information
Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 250 words) can be sent to the Editorial Office for assessment.
Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-anonymized peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Geosciences is an international peer-reviewed open access monthly journal published by MDPI.
Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 1800 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
