Hydrothermal processes refer to a variety of geological and industrial phenomena in which water or aqueous solutions circulate at elevated temperatures and pressures, facilitating the alteration of rocks, mineral deposition, or fluid transport. In Earth’s crust, hydrothermal fluids originate from magma, metamorphic reactions, or meteoric water that has penetrated deep fissures. As these fluids travel, they dissolve and re‑precipitate minerals, creating ore deposits such as porphyry copper, epithermal gold, and massive sulfide systems. The chemistry of the fluids, driven by temperature gradients and the composition of host rocks, determines the mineral assemblages that form.

Industrial applications of hydrothermal processes include the synthesis of high‑purity semiconductors, ceramic materials, and nanomaterials, where reaction vessels are heated under controlled hydrostatic pressures. In the petroleum sector, hydrothermal techniques are employed in enhanced oil recovery by injecting heated brine to mobilize viscous hydrocarbons. Environmental remediation also uses hydrothermal oxidation to treat contaminated groundwater, as the high temperatures accelerate the breakdown of organic pollutants. Regulatory frameworks for industrial hydrothermal operations emphasize monitoring of effluent temperatures, pressure containment, and containment of potentially hazardous by‑products.

Research on hydrothermal systems has advanced through both field monitoring and laboratory simulation. Geophysical methods such as seismic tomography and electrical resistivity imaging reveal fluid pathways, while geochemical tracers (e.g., stable isotopes and rare earth elements) help reconstruct temperature–pressure histories. Recent advances in high‑resolution imaging and microfluidic modeling have refined our understanding of mineral growth rates and fluid‑rock interaction kinetics. These insights inform resource exploration, hazard assessment, and the development of sustainable technologies that harness hydrothermal energy and materials.
