Further, this 2017 paper in , Carbon fixation from mineral carbonates, confirms that cynobacteria in fossils get "virtually all" of their carbon from the bone substrate they are feeding on!Therefore they cannot "contaminate" the 14c results because they will carbon "date" the same as the bone itself, for their percentage of modern carbon is identical to that of the bone.Contamination is not only far more unlikely within deep-mined and unbroken diamonds, but because of the unique physical composition of diamonds, various kinds of contamination could be more readily detectable.: Just as forensic accountants can often determine when a criminal business has cooked its books merely by doing a Benford statistical analysis of the numbers, so too mathematicians have demonstrated that statistical analysis can indicate whether scientific data is likely a result of measurement errors.So evolutionists typically claim that all this 14c results from contamination, but statistical analysis indicates that when plotting erroneous dates (as from contamination), the data should fit a normal curve. As documented by Rick Sanders in in CRSQ, the distribution provides significant evidence that the radiometric ages do not result from contamination errors.Carbon-14 has a half-life of about 5730 years, so researchers use the process to date biological samples up to about 60,000 years in the past.Beyond that timespan, the amount of the original C formed by irradiation of nitrogen by neutrons from the spontaneous fission of uranium, present in trace quantities almost everywhere.Paul Giem himself, graded the information presented below. He gave the original text (available here) a grade of A minus.
interdigitated with its neighboring microfibrils... so well ordered as to be crystalline." Further, bacteria do not make collagen, which eliminates another possible source of contamination.
* Carbon-14 is Everywhere so it Can't Be an Anomaly: Carbon-14 doesn't lie. And it's so unstable that all 14c atoms in a sample would radioactively decay in far less than a million years.
So, such radiocarbon in allegedly older samples could theoretically come from a secondary source like contamination, background noise, or neutron capture. For example, living bacteria might infest a dinosaur bone but the journal reports that this doesn't affect its carbon date because the bacteria doesn't feed on the 14c in the atmosphere but in the bone!
Thus, when significant quantities of 14c are found, for example, in coal and dinosaur bones, as well as in diamonds, the least contamination-resistant 14c-rich specimens provide a constraint on the likelihood of contamination as a primary source for the modern carbon in other similarly-dated specimens.
Thus the radiocarbon content of diamonds is all the more compelling and important, and especially when the specimens are mined from a quarter-of-a-mile below the surface, insulated from our 14c-bearing atmosphere.
