That wasn't my dream, it was Cornell Universities lecture that said that Ar40Ar36 is 20,000 times greater than is Ar40Ar36 in the atmosphere
It's not polite to make a claim like that without providing the reference in the message where you make the claim.
Of course and as usual, you are wrong. At
http://www.geo.cornell.edu/...6notes03/656%2003Lecture06.pdf we find:
"Atmospheric argon has a constant 40Ar/36Ar ratio of 295.5 ... some samples can have "initial" 40Ar/36Ar ratios greatert than the atmospheric ratio; this can lead to too old an age
if not properly accounted for {emphasis added - JRF} ... For example, mantle-derived basalts have been shown in some cases to have 40Ar/36Ar ratios in excess of 20,000. The 40Ar/36Ar ratio reflecs the production of 40Ar by decay of 40K within the mantle. Minerals crystallizing in the presence of this gas will trap some of this 40Ar, which will result in an anomolously old age upon analysis."
The rest of the lecture is concerned with
how this problem is detected and accounted for.
So,
some but
not all basalts have a 40Ar/36Ar ratio that is 20000/295.5 =
67.7 times larger than the atmospheric ratio, not 20,00 times larger as you claimed, and
more than two orders of magnitude less than you claimed. Your 20,000 times larger is a pipe dream that you made up, based on an incredible misreading of a plainly written paragraph..
The situation mentioned
does not occur in all analyses and can be
detected and
corrected in the manners described in that paper and the literature. This is known because
Ar-Ar dating results agree with so many other results that are not affected by high Ar40/Ar36 ratios. Until you have addressed the consistent results obtained by different dating methods, you have not done anything.
We are taking contamination into account.
We are not dating sediments, we are dating igneous rocks. If you don't understand this and understand why, you know nothing.
You have no idea of the realities of how diffusion works, or how mass transport works, or the theories or the realities of how dating is done, or the real-world data that has been collected.
