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.

Anything over about 50,000 years old, should theoretically have no detectable C.

So, we have a “clock” which starts ticking the moment something dies.

Obviously, this works only for things which were once living.

It does not give dates of millions of years and when corrected properly fits well with the biblical flood.

There are various other radiometric dating methods used today to give ages of millions or billions of years for rocks.

Familiar to us as the black substance in charred wood, as diamonds, and the graphite in “lead” pencils, carbon comes in several forms, or isotopes.

One rare form has atoms that are 14 times as heavy as hydrogen atoms: carbon-14, or C ratio gets smaller.

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.

For example, potassium-40 decays to argon-40; uranium-238 decays to lead-206 via other elements like radium; uranium-235 decays to lead-207; rubidium-87 decays to strontium-87; etc.

It cannot be used to date volcanic rocks, for example.
