Earth has been expelling volatiles ever since its formation ~4.56 billion years ago. The degassing of solid Earth redistributes volatile elements (e.g., CO2 and noble gases) in Earth from the interior to the surface, especially the atmosphere of which the variations in CO2 levels over geological history have modulated the climatic and environmental conditions of Earth’s surface and its habitability. Under the regime of modern plate tectonics, the release of deeply-sourced fluids (including volatile species and groundwater) by volcanic and tectonic processes prevails in different geological units of oceanic and continental settings. Thus, the fluid origin and transport in volcanically and tectonically active regions have long been regarded as an essential research topic in Earth Sciences.
Recent developments in the techniques involved in field-based observations and laboratory analysis have facilitated the applications of gas geochemistry and hydrogeochemistry to a large number of research fields in Earth sciences such as hazard mitigation and resource exploration. However, from a global point of view, the volcanic and tectonic controls on origin and transport of deeply-sourced fluids are still not well constrained for different plate tectonic settings. Moreover, our human society is facing with potential threats of hazards such as volcanic eruptions and earthquakes. New studies on fluid (gas + water) geochemistry of the volcanically and tectonically active regions would provide critical insights into origin and transport of the fluids, which further contribute to hazard mitigation and other related scientific and social aspects.
This research topic aims to collect potential contributions on new advances in fluid geochemistry that focus on volcanically and tectonically active regions worldwide. We welcome the contributions based on applications of fluid geochemistry and other multi-disciplinary approaches to understanding origin and transport of the deeply-sourced fluids and their implications for geological processes and human society. The potential research themes include but are not limited to:
• monitoring of active volcanoes;
• earthquake forecasting and nucleation theory;
• noble gas geochemistry;
• stable isotope geochemistry;
• gas-water-rock interaction;
• groundwater circulation;
• volcanic and tectonic CO2 emissions;
• geothermal energy evaluation;
• exploration of helium and other gas resources.
