The age of the earth. If the requirements of the method have been violated, the data clearly show it. This can be seen in the concordia diagram, where the samples plot along an errorchron straight line which intersects the concordia curve at the age of the sample. Thus, the radiometric ages obtained from these oldest rocks are not necessarily the age of the first event in the history of the rock.
