Image : Hydrothermal Circulation Beneath and Within Active Vent Deposits: A Preliminary Model of the Effect of Chemical Reaction on Fluid Flow
Last updated: August 19, 2016
Fluid flow and water-rock interaction have important implications for changes in the chemical and physical properties of the seafloor and for exchange of heat and matter between the Earth's interior and the oceans. The chemical reactions and mineralogical transformations in the upper crust take place very slowly and chemical equilibrium is usually not attained. Microorganisms have developed strategies to catalyze geochemical reactions and use the chemical energy released for cellular growth.
