. carbon-14, or 14c) keeps popping up reliably in samples (of coal, oil, gas, etc. studies of the ancient biosphere indicate that there was several hundred times as much carbon in the past, so the 14c/c ratio would have been several hundred times smaller..So if samples were really over a million years old, there would be no radiocarbon left. as long as the tree lives, it absorbs carbon from the atmosphere in the form of carbon dioxide, both c-12 and c-14.-argon and argon-argon dating of crustal rocks and the problem of excess argon.
presence of measurable radiocarbon in fossil wood supposedly tens and hundreds of millions of years old has been well-documented. normally occurs as carbon-12, but radioactive carbon-14 may sometimes be formed in the outer atmosphere as nitrogen-14 undergoes cosmic ray bombardment., many dating methods that don't involve radioisotopes—such as helium diffusion, erosion, magnetic field decay, and original tissue fossils—conflict with radioisotope ages by showing much younger apparent ages.’2 also, if atmospheric contamination were responsible, the entire carbon content would have to be exchanged every million years or so."excess argon": the "archilles' heel" of potassium-argon and argon-argon "dating" of volcanic rocks.
observations give us confidence that radiometric dating is not trustworthy. (these include the variety of elements used in ‘standard’ radioisotope dating, mature uranium radiohalos and fission track dating. in the following article, some of the most common misunderstandings regarding radiocarbon dating are addressed, and corrective, up-to-date scientific creationist thought is provided where appropriate. and as dr paul giem points out: ‘one can hypothesize that neutrons were once much more plentiful than they are now, and that is why there is so much carbon-14 in our experimental samples.’ barry lynn, leader of the anti-christian group americans united for the separation of church and state, proclaimed in a nationally televised debate, ‘carbon dating, that shows the earth is billions of years old!
of these different types (isotopes) of carbon, 14c is called radiocarbon, because it is radioactive—it breaks down over time. if neutron capture is a significant source of carbon-14 in a given sample, radiocarbon dates should vary wildly with the nitrogen content of the sample. hoesch, "radioisotopes in the diabase sill (upper precambrian) at bass rapids, grand canyon, arizona: an application and test of the isochron dating method," in proceedings of the fifth international conference on creationism, r. but the flood must have buried huge numbers of carbon-containing living creatures, and some of them likely formed today’s coal, oil, natural gas and some of today’s fossil-containing limestone. since no one, creationist or evolutionist, thinks there has been an exchange of carbon in the diamond with the atmosphere, using the standard formula for 14c dating to work out the age of a diamond is meaningless.
carbon dating says nothing at all about millions of years, and often lacks accuracy even with historical specimens, denying as it does the truth of the great flood."excess argon": the "archilles' heel" of potassium-argon and argon-argon "dating" of volcanic rocks. it is only useful for once-living things which still contain carbon, like flesh or bone or wood. the credibility of our work in creation science research depends on these costly but crucial laboratory procedures. diamonds’ carbon-dated ‘age’ of about 58,000 years is thus an upper limit for the age of the whole earth.
