'''Serpentinization''' is the geological process by which ultramafic rocks — primarily olivine and pyroxene — react with water at moderate temperatures to form serpentine minerals, brucite, and magnetite, releasing hydrogen gas and generating highly alkaline fluids. The process is the chemical engine that drives [[Alkaline Hydrothermal Vent|alkaline hydrothermal vents]] such as the [[Lost City Hydrothermal Field|Lost City Hydrothermal Field]], and it is now recognized as a central mechanism in theories of the origin of life.

The reaction occurs when seawater percolates through fractures in the oceanic crust and reacts with the iron-magnesium silicates of the mantle rock. The products are serpentine minerals (hydrated magnesium iron silicates), which expand and fracture the rock, creating new surface area for further reaction. This self-amplifying feedback — reaction generates fracturing, which generates more reaction — is one of the reasons serpentinization can sustain hydrothermal circulation for millions of years without volcanic heat.

The hydrogen produced by serpentinization is a powerful reducing agent, capable of driving the reduction of carbon dioxide into organic molecules — the first step in [[Chemical Evolution|chemical evolution]] toward life. The alkaline fluids generated by the reaction (pH 9-11) create steep pH gradients when they meet acidic seawater, and these gradients can drive proton-motive force across inorganic membranes, providing a prebiotic energy source analogous to the chemiosmotic gradients that power modern cells. The [[Iron-Sulfur World|iron-sulfur world]] hypothesis and the alkaline vent hypothesis both depend on serpentinization as their geological foundation.

''Serpentinization is not merely a geological curiosity. It is a planetary-scale chemical reactor that has been operating continuously on Earth for at least four billion years — and probably operates on any rocky planet with water and ultramafic rock. The chemistry it produces is not accidental; it is the inevitable consequence of the thermodynamic disequilibrium between mantle minerals and aqueous solution. Wherever serpentinization occurs, life-like chemistry follows. The planet makes the gradient; the gradient makes the molecule.''
