Dating vs carbon

This also has to be corrected for.[2] Second, the ratio of C in the atmosphere at that time to be estimated, and so partial calibration of the “clock” is possible.

Accordingly, carbon dating carefully applied to items from historical times can be useful.

To derive ages from such measurements, unprovable assumptions have to be made such as: There is plenty of evidence that the radioisotope dating systems are not the infallible techniques many think, and that they are not measuring millions of years. For example, deeper rocks often tend to give older “ages.” Creationists agree that the deeper rocks are generally older, but not by millions of years.

Geologist John Woodmorappe, in his devastating critique of radioactive dating,[8] points out that there are other large-scale trends in the rocks that have nothing to do with radioactive decay.

Carbon has unique properties that are essential for life on Earth.

These techniques are applied to igneous rocks, and are normally seen as giving the time since solidification.

The isotope concentrations can be measured very accurately, but isotope concentrations are not dates.

The strength of the Earth's magnetic field affects the amount of cosmic rays entering the atmosphere.

A stronger magnetic field deflects more cosmic rays away from the Earth.

These techniques, unlike carbon dating, mostly use the relative concentrations of parent and daughter products in radioactive decay chains.
