Diffusion measurements and the potassium argon method of dating
The discussion of some phenomena taking place during rock crystallization reveals huge discrepancies between the model theory and the reality.Anomalous « K/Ar model ages » are frequently reported in the literature.
The choice of these initial conditions affects the results.
These investigations suppose complete coordination between different disciplines and laboratories.
The experimental method applied to events in the past.
As an illustration, the next paragraph will focus on the very popular potassium/argon method (K40/Ar40).
Potassium/Argon Method This method, based on the accumulation of the radiogenic noble gas argon (Ar40) derived from potassium 40 (K40) decay, also depends on fundamental assumptions.
