This procedure depends on temporal placement of fragments of wood using carbon-14 (C age and that also extends to a younger age.A tree ring pattern that matches is found close to where the carbon ‘dates’ are the same. It assumes that it is approximately correct to linearly extrapolate the carbon ‘clock’ backwards. The closer one gets back to the Flood the more inaccurate the linear extrapolation of the carbon ‘clock’ would become, perhaps radically so.So the carbon ‘date’ is used to constrain just which match is acceptable.Consequently, the calibration is a circular process and the tree ring chronology extension is also a circular process that is dependent on assumptions about the carbon dating system.There are many points in a given sequence where a sequence from a new piece of wood matches well (note that even two trees growing next to each other will not have recognized that ring pattern matches are not unique.The best match (using statistical tests) is often rejected in favour of a less exact match because the best match is deemed to be ‘incorrect’ (particularly if it is too far away from the carbon-14 ‘age’).) of the White Mountains of Eastern California, were dated in 1957 by counting tree rings at 4,723 years old.This would mean they pre-dated the Flood which occurred around 4,350 years ago, taking a straightforward approach to Biblical chronology.

Today, there are over 130 radiocarbon dating laboratories around the world producing radiocarbon dates for the scientific community.

And so the tree-ring sequence is extended from the living trees backwards. Conventional carbon-14 dating assumes that the system has been in equilibrium for tens or hundreds of thousands of years, and that , chapter 4).

The biggest problem with the process is that ring patterns are not unique.

Welcome to the K12 section of the Radiocarbon WEBinfo site.

The aim here is to provide clear, understandable information relating to radiocarbon dating for the benefit of K12 students, as well as lay people who are not requiring detailed information about the method of radiocarbon dating itself.
