Three assumptions of radiometric dating

The third assumption is that the sample has remained in a closed system.

And even though various radioactive elements have been used to "date" these rocks, for the most part, the methods are basically the same. This means that if you had some pure uranium-238 with no lead in it, 4.5 billion years later one half of it would have decayed into its stable daughter product (lead-206). Where these alpha particles finally stop, crystal deformation occurs (and) shows up as a discolouration or a darkening of the crystals.The following tables illustrate the highly questionable, if not totally unreliable, nature of the radiometric methods that are currently in use or have been used in the past to "date" volcanic materials. For the reasons discussed above, radiometric dating is not the absolute Time Clock that it has been portrayed to be by faithful evolutionists. 65,35) was not given, the ratios of Potassium -40 (K)/ Argon-40 (Ar) were listed in Table 1 on p. And though I agree with the writers of this article that this sample has an excess amount of Argon-40, I also think it is highly probable that the argon which contaminated this sample also contaminated all of the other samples, and that this breccia was simply "contaminated" with more Argon.See the links below for more detailed information on this topic. The only dating methods discussed (over and over) by evolution-believing scientists and the mass media are those that supposedly "prove" that the earth is billions of years old.One of the most popular of these is known as radiometric dating. can be In other words, something in the past caused a significant amount of helium to build up inside these zircons (such as from a rapid decay episode of uranium), yet, in spite of the fact that helium has been observed to leak out readily from these zircons, it has not done so: simply because it hasn't had enough time to do so -- suggesting that the zircons themselves are only a few thousand years old."There is evidence to show ...

If, on the other hand, it is found that the radii vary, then this is proof that the half-life of that decay is not constant.
