Measured radiocarbon dating organic materials dating someone younger than 18

They found a detectable amount of surface contamination was present in the first fraction collected, but it was not large enough to make the result from the final gas fraction significantly different from the average value.

They also leached samples in hydrochloric acid for two hours and cracked open the foraminifera shells to remove secondary carbonate from inside, but these procedures did not significantly alter the measured The results …

In retrospect, it is likely that many of the beta-counting analyses were indeed truly detecting intrinsic C in pre-Flood organic materials fossilized in Flood strata therefore appears to represent a powerful and testable confirmation of the young earth Creation-Flood model.

It was on this basis that Snelling3C “dead” because it was derived from Tertiary, Mesozoic, and upper Paleozoic strata having conventional radioisotope ages of 40 to 250 million years.

.) An astonishing discovery made over the past 20 years is that, almost without exception, when tested by highly sensitive accelerator mass spectrometer (AMS) methods, organic samples from every portion of the Phanerozoic record show detectable amounts of C/C ratios from all but the youngest Phanerozoic samples appear to be clustered in the range 0.1–0.5 pmc (percent modern carbon), regardless of geological “age.” A straightforward conclusion that can be drawn from these observations is that all but the very youngest Phanerozoic organic material was buried contemporaneously much less than 250,000 years ago.

This is consistent with the biblical account of a global Flood that destroyed most of the air-breathing life on the planet in a single brief cataclysm only a few thousand years ago.

These included progressive stepwise acid hydrolization of the carbonate samples to COC measurement of each of four separate gas fractions.

Many of the samples they analyze are shells and foraminifera tests from sediment cores.

It would very useful to them if they could extend the range for which they could date such biological carbonate material from roughly 40,000 years ago (according to their uniformitarian assumptions), corresponding to about 1 pmc, toward the 0.002 pmc limit of their AMS instrument, corresponding to about 90,000 years in terms of uniformitarian assumptions.

We draw several observations from this comparison, imprecise as it may be.

First, the set of samples with biological affinity display a mean value significantly different from those without such affinity.

Most of the graphite samples with C/C values below 0.05 pmc are in this category.
