And the K-Ar model "ages" are so widely divergent from one another (ranging from 405.1±10 Ma to 2574.2±73 Ma), even from very closely spaced samples from the same outcrop of the same original lava flow, as to be useless for "dating" any event.

The computer program Isoplot was used to plot isochrons and calculate isochron ages from the other radioisotope analyses.

The best isochron plots, where all the variation from the line of best fit to the data incorporates all the analytical errors, yielded an Rb-Sr isochron age of 1240±84 Ma, an Sm-Nd isochron age of 1655±40 Ma, and a Pb-Pb isochron age of 1883±53 Ma.

To the contrary, the rocks could still only be a few thousand years old.

The radioisotope methods, long touted as irrefutably dating the earth's rocks as countless millions of years old, have repeatedly failed to provide reliable and meaningful absolute ages for Grand Canyon rock layers.

These were originally basalt lava flows several meters to tens of meters thick.

In some outcrops pillow structures have been preserved, testimony to the basalt lavas having originally erupted and flowed under water onto the Creation Week ocean floor.

Most people believe that when the different radioisotope dating methods are used on the same rock unit they all yield the same age.

However, the radioisotope dating of these Grand Canyon rocks clearly demonstrates that the disagreement, or isochron discordance, is pronounced.

The "age" or "date" is calculated from the amount of the daughter isotope produced by radioactive decay of the parent isotope.
