C14 in Diamonds: evidence of a young earth? : askscience

c-14 dating diamonds

Notice, this is not about dating diamonds, it's about the fact that there is C-14 inside diamonds at all. There seem to be some unsubstantiated references to the possibility of neutrons generated by uranium decay resulting in an anomalously high presence of C14. It is produced in the upper atmosphere. If C-14 entered during the formation of the diamond, it would have disappeared within the first 100,000 years. Question: What specifically does C-14 dating show that creates problems for the creation model? In the above mentioned article penned by Snelling, the first diamond they subject to carbon dating yields an age of 55,000 years. Question: Kieth and Anderson radiocarbon-dated the shell of a living freshwater mussel and obtained an age of over two thousand years. Now if the magnetic field several thousand years ago was indeed many times stronger than it is today, there would have been less cosmic radiation entering the atmosphere back then and less C-14 would have been produced.

If the problem is radiation from outer space, then why do some bones date to 20,000 years, others to 40,000 years? We will discuss in detail the discovery of Dr. In other words, the readings are consistent with zero C14 content. K-40 decay also forms plenty of beta radiation. You see, carbon-14 has a half life of 5,730 years, and every isotope undergoes many half lives in its decay. Those who propose radical changes risk damage to their careers and ridicule.

Diamonds: a creationists best friend

Given that several isotopes have extremely long half-lives, for example, U 238 has a half-life of 4,500,000,000 years, and Th 232 has a half-life of 14,050,000,000 years, and several of the daughter isotopes also have usefully long half-lives, one can determine the age of a rock sample, where multiple isotopes are present, by relating them to the correct decay series and utilising the observed empirically determined half-lives of laboratory samples to determine the age of a particular rock sample, cross correlating using multiple isotopes where these are present and enable such cross correlation to be performed. Here are more quotations from the Science article referenced above: Last week in the Journal of Proteome Research, Schweitzer, her postdoc Elena Schroeter, and colleagues report that they did a complete makeover of their 2009 experiment to rule out any possible contamination. At best, your argument suggests there is a flaw in C14 dating. In other words, it rose in intensity from 0. Answer: If anything, the tree-ring sequence suffers far more from missing rings than from double rings. But the number of neutrons required must be over a million times more than those found today, for at least 6,000 years. I'll see if I can dig up some references I had at one point.

. According to evolutionists, the diamonds formed about 1—3 billion years ago. Also, there is background noise. Therefore the Earth must be at least 7,360,000 years old for all the Bi 208 to have disappeared. The method works best for micas, tektites, and meteorites. By the way, yes, I misspoke in the video about C14 being produced from C12 in the atmosphere; it's produced from nitrogen atoms, not carbon atoms.

Young earth creationists and Carbon

Geologists believe that the ones we find must have been transported supersonically to the surface, in extremely violent eruptions through volcanic pipes. Do you have that in a full-color pamphlet for me to hand out? Answer: C-14 dates show that the last glaciation started to subside around twenty thousand years ago. Therefore, over geological time, the data points will move upwards and to the left. 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. It doesn't take much contamination to spoil a sample with near-zero quantity of C14. I'm probably teaching grandmother to suck eggs, as the old saying goes.

Thus the concentration of uranium and thorium in the dinosaur bones is near or in the normal range. One measures the radiation from it. The rate at which carbon 14 is produced has reached equilibrium with the rate at which carbon 14 naturally decays back into nitrogen. This figure is for contamination from recent organic matter. A chart of the ratio of D to L for samples of various radiocarbon ages shows that even for samples dated to 30,000 or 40,000 years, the ratio of D to L is significantly less than one. As for the question of polarity reversals, plate tectonics can teach us much.

Concerning the sequence of rings derived from the bristlecone pine, Ferguson says: - page 26 - In certain species of conifers, especially those at lower elevations or in southern latitudes, one season's growth increment may be composed of two or more flushes of growth, each of which may strongly resemble an annual ring. John Baumgardner, of Los Alamos National Labs has documented in Dec, 2010 Creation Matters that C-14 exists even in the hardest naturally-occurring, contamination-resistant substance on earth, within diamonds. Thus they probably formed at a depth of 100—200 km. This is because because the half-lives of all these radionuclides are a good deal longer than 6,000 years. He found that the earth's magnetic field was 1. Now, having covered this, it's time to deal with a topic of importance, and one that constitutes another of those epistemological bones creationists love to chew upon, without realising that the questions surrounding this topic have already been answered.

Finally, some graphite samples from the Precambrian era were dated, giving ages of 58,400-70,100. Organic matter in the fossil record generally dates by carbon 14 C14 dating to about 20,000 to 40,000 years. This can be performed by performing precise quantitative measurements of parent radionuclides and daughter products, all of which is well within the remit of inorganic chemists since the chemistry of the relevant elements has been studied in detail, in some cases for over 200 years and of course, modern gas chromatograph mass spectrometry can be brought to bear upon the process, yielding results with an accuracy that past chemists reliant upon earlier techniques could only dream of. The radiocarbon dates and tree-ring dates of these other trees agree with those Ferguson got from the bristlecone pine. The most plausible explanation is contamination. Answer: Cosmic rays in the upper atmosphere are constantly converting the isotope nitrogen-14 N-14 into carbon-14 C-14 or radiocarbon.

This means that at some point your radiation from C14 would be less than the fluctuations in background, making it untdetectable. Young earth proponents use the term to refer to any branch of science that disagrees with them even if it has nothing to do with the theory of evolution, including biology, ecology, paleontology, archaeology, geology, botany, oceanography, astronomy, cosmology, meteorology, and anthropology, not to mention the many subdisciplines and interconnecting fields within all of these sciences. It's relative to our current ppm. Transport - And How Scientists Deal With It Even in the very early days of the development of radionuclide dating techniques, scientists were aware that chemical elements in rock samples might be subject to various chemical processes resulting in the transport of material in or out of a given rock sample. Many creationists believe that radioactive decay was faster in the past.
