The "age" or "date" is calculated from the amount of the daughter isotope produced by radioactive decay of the parent isotope.In Grand Canyon, the "date" of metamorphism of the basalt lavas to form these Brahma amphibolites has been determined as 1690-1710 Ma (million years ago), based on U-Pb dating of minerals in the overlying Vishnu Schist and underlying Rama Schist that formed during the metamorphism.

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.In other words, the decay of the parent radioisotopes was accelerated by different amounts, the decay of those yielding older "ages" (the alpha-decayers) having been accelerated more.Obviously, if radioisotope decay was accelerated, say during the Genesis Flood, then the radioisotope decay "clocks" could never be relied upon to "date" rocks as many millions of years old.Both laboratories use standard, best-practice procedures on state-of-the-art equipment.The model K-Ar ages for each of the samples ranged from 405.1±10 Ma to 2574.2±73 Ma.

Irreconcilable disagreement within and between the methods is the norm, even at the outcrop scale.
