Describes a radioactive dating, the rather messy medium of organic materials.
Getting back to my OP - I feel that some definitive work needs to be done in this area. It's easy to see that the sceptical creationist is simply going to see the scientific response as making excuses for the data instead of holding up some hard data that either explains or explodes the anomaly.
Another thing I've heard from creationists is that fossils made by soaking samples in tar pits appear to be extremely old.
Oct 01, The reliability of radiometric dating is subject to three ujankossencontemporary.comovable assumptions that every geologist must make when using the radioactive "clock". Radioactive rocks offer a similar "clock." Radioactive atoms, such as uranium (the parent isotopes), decay into stable atoms, such as lead (the daughter isotopes), at a measurable jankossencontemporary.com: Dr. Andrew A. Snelling. More Bad News for Radiometric Dating How anyone can keep track of this all is a mystery to me, especially with the difficulties encountered in exploring magma chambers. Vulcanello, and Lipari and other volcanic sites. The only place where radioactive equilibrium of the U series exists in zero age lavas is in Hawiian rocks. Thus. Processes or Time. To date rocks or other objects, scientists typically use radiometric jankossencontemporary.com short, the ratio of radioactive and stable isotopes in the sample are determined and the measured rate at which the isotopes decay is used as an indicator of the age of the sample. However, it is typically unknown and simply assumed whether these ratios of elements are the result of .
Of course, the problem is that this process results in contamination with old carbon, making the sample appear older. In the case of old samples with almost no C, even the tiniest bit of contamination would make the sample appear far younger. Always remember that C dating is not a magical process; it is a measure of C and the age interpretation depends on a few assumptions. It's also worth noting that C is only useful for a bit more thanyears. The vast majority of fossils aren't dated using C at all, but other radioisotopes.

Science has several very reasonable explanations for levels of modern carbon in very old samples. Although this satisfies the scientist, who for all sorts of other reasons quite reasonably assumes that these samples are truly old, it leaves enormous scope for the creationists to reinforce their followers' faith that the earth is young.
I still feel that some definitive experiments in this area would be useful to test the various rational explanations for the c14 anomaly.
I can see though that science has problems taking on creationists because of the perceived risk of lending credibility to their ideas. Bit of a dilemma there. Also as soon as one creationist idea is exploded, they just move on to another area where uncertainty in the science offers them the opportunity to mislead.
That begs the question that an anomaly even exists. What does exist are limits to the applicability of 14 C dating techniques. Several of the test results touted by creationists were definitive experiments to assess those limitations. There is no arguing with young earth creationists. They are immune to logic and evidence.

Broadly speaking I agree with you. But, reading the experts' explanations of the "anomaly" read to me, as a non-expert in this field, like perfectly reasonable explanations as long as you accept the "old earth" explanation.
If you don't, such dismissive arguments as 'the extra C14 could be due to uranium decay' leave enough wriggle room uncertainty for the creationist to thrive in. You're right though, I'm probably being naive in thnking they will be convinced. Even so, it is always good when creationists have been casting doubt in some area to be able to completely explode their reasoning.
I'm still looking for a reference, in a refereed scientific journal, confirming the finding of carbon14, in any amount, in diamonds or coal. I suspect, but haven't been able to confirm, that the reports of carbon 14 in these substances have been made up out of whole cloth by Young Earth Creationists, but I am loath to make this claim, absent evidence that reports of these findings haven't been published in any journals that aren't connected with such organizations as the Institute for Creation Science.
I further think that it is the fact that the claims are conscpicuously bogus that has accounted for their not having been responded to. After all, to my limited understanding, carbon 14 is associated with organic processes, and, right off the bat, I find myself wondering why it would be found in any allotrope of carbon, which is an inorganic element. Can anyone out there either confirm or disconfirm my suspicions? You need to know that I will not be much impressed by anything coming from the ICR or any similar group.

Feb 17, Ive been poking about on the internet again (as you do) and found a whole load of stuff by creationists about the problems with carbon 14 radiometric dating.

Well one of two things could be happening, the carbon 14 signature is reset every time the rock melts because the carbon 14 disperses among the liquid rock, Also neutron bombardment from uranium decay could possibly have an impact, but you'd also have other trace elements that tell the tale of this neutron contamination. Since the discussion is specifically about Carbon14 in coal I am unclear as to why you would be talking about molten rock.
Coal is not known for its inclination to melt.
Since Carbon14 dating is only relevant to dating organic matter I am unclear as to why you would be talking about resetting the Carbon14 clock in molten rock.
