1/6/1998· Patterson points out that data for young Earth sediments fall on the same isochron; this implies that the Earth shares a common origin with the dated meteorites. Though only a few meteorites had been dated at this point in time, and the individual meteorite ages that did exist were not very precise, they also agree with the isochron age.
