40 Ar/39 Ar Thermochronology
Abstrak
Abstract In the previous chapter we reviewed both the conceptual and mathematical foundations of diffusion in solids and showed that the Arrhenius relationship could be linked with solutions of the diffusion equation (for a constant D) to yield an expression that relates temperature and heating duration to the degree of argon loss [eq. (5.26)1 Although useful as an illustration of how knowledge of diffusion parameters can be used to extract thermal history information from a disturbed isotopic system, the underlying assumptions inherent in this equation (i.e., a heating episode of constant temperature and short duration relative to the time of argon accumulation) restrict its geological application to rather few circumstances.
