Well it seems that my declaration of imminent victory way back when was rather premature. I underestimated Mindspawn's willingness to dig in his heels in the face of evidence. But I think it is now safe to say that RAZD has fact-hammered him into submission. Victory for RAZD Fact-hammer!
I revisited CMI and found an article by Woodmorappe attempting to debunk conventional dating. He referenced an article in Science 292(5526) 2453-2458, 29 June, 2001, and stated it showed up to a 10.000 year discrepancy between the dates from Suigetsu and C14 in the 10,000 to 40.000 year range. I know a lot of work has been done since, but does anyone have access to the original article to comment?
The article Woodmorappe references does indeed show a lot of variation in C14 , but in trying to refute Lake S.'s data, what he omits is telling. The study is on a speleothem, and there is very good agreement with LS out into the 30.000s, with of course their basic agreement with C14 measurements. It is only into the 40,000s that there are some wild swings of C14 shown. They also show agreements into the 30s with other studies - Lake Nisan, Cango cave, and 4 others.
So his reference is providing evidence against his case - I guess a depressingly common thing at ICR.
