And when I look at the Wikipedia article, the discussion is so technical and defensive that I can't actually picture what is going on. You are right: there is no decay of 40-Ar into 39-Ar. The difference between measured 40-Ar and 40-Ar at formation is used in the procedure.

But then, different passages in the Wikipedia article contradict each other (first section: 39-K is converted into 39-Ar by neutron bombardment; but "age equation" section: 40-K is bombarded; I think it should be 39-Ar).

The age of meteorites and volcanic stones are measured by this method.

His crown was a simple circlet of Valyrian steel, set with big square-cut rubies. He was a solitary person whose only friend was Orys Baratheon.
