Half Life

For example, the rubidium-strontium method would give a valid isotopic age of the biotite sample with inherited argon.

  • Excess argon may be derived from the mantle, as bubbles trapped in a melt, in the case of a magma.

  • This indicates that some excess argon is present.

So in both cases the Argon flows down the concentration gradient.

  • Under favourable circumstances the isochron method may be helpful, but tests by other techniques may be required.

  • As I mentioned before, one sometimes finds significant argon 40 in a rock and no potassium at all, as mentioned in Snelling's article.
