From careful physics and chemistry experiments, we know that parents turn into daughters at a very consistent, predictable rate.For an example of how geologists use radiometric dating, read on: A geologist can pick up a rock from a mountainside somewhere, and bring it back to the lab, and separate out the individual minerals that compose the rock.Das Beschleuniger-Massenspektrometrielabor wurde mit dem Ziel gegründet, Einrichtungen der Christian-Albrechts-Universität und des Landes Schleswig-Holstein sowie Kunden aus aller Welt, radiometrischen Datierungsservice anzubieten.

As one example, the first minerals to crystallize (condense) from the hot cloud of gasses that surrounded the Sun as it first became a star have been dated to 4568 plus or minus 2 million years....!! Other events on earth can be dated equally well given the right minerals.

For example, a problem I have worked on involving the eruption of a volcano at what is now Naples, Italy, occurred 38500 years ago with a plus or minus of 300 years.

Radiometric dating relies on the principle of radioactive decay.

All radioactive isotopes have a characteristic half-life (the amount of time that it takes for one half of the original number of atoms of that isotope to decay).

This gives geologists great confidence that the method correctly determines when that rock formed.
