Some experimental and theoretical observations on the kinetics of hydration reactions with particular reference to serpentinization

摘要: Abstract The rates of hydration forsterite to serpentine and brucite enstatite talc, have been experimentally investigated. are rapid in relation geological times it is suggested that the natural processes diffusion controlled. reactions characterized by small activation energies large unfavourable entropies activation. Theoretical aspects kinetic data discussed with particular reference concept “retrograde kinetics”, a phenomenon critical significance extrapolation laboratory geologic times.
