Radiometric dating relative dating
A detailed survey of the following dating methods in actual use: K-Ar, Ar-Ar, Fission track, Rb-Sr, U-Pb, Pb-Pb, Sm-Nd, Re-Os, Lu-Hf, La-Ce, etc.Addresses and refutes the common defensive statements used by proponents of the dating methods.Thus, while a rock is molten, the 40Ar formed by the decay of 40K escapes from the liquid.It seems like rocks dating within one or two million years cannot be accurately dated by K-Ar techniques just because of the relatively wide ranges of error.

What most people dont realize, or at least dont discuss, is that Ar/Ar method is not an absolute dating method.
Let me emphasize again that this dating method is a relative dating method.
So the so-called absolute radiometric dating methods themselves are not absolute.
It is a misleading term which is much used by evolutionists in order to seemingly prove the unobservable old age of the earth.
