👉 Geofluids, also known as hydrogeological fluids, are mixtures of water and dissolved or suspended materials that move through the Earth's subsurface environments. They play a crucial role in various geological processes, including groundwater flow, sediment transport, and the formation of mineral deposits. These fluids can exist in various states—liquid, vapor, or slurry—and are influenced by factors such as temperature, pressure, and the composition of the surrounding rock. Geofluids are essential in understanding subsurface water resources, contaminant transport, and the dynamics of hydrothermal systems, making them a fundamental concept in geology and environmental science.
