Another method is to make age measurements on several samples from the same rock unit.This technique helps identify post-formation geologic disturbances because different minerals respond differently to heating and chemical changes.Whenever possible we design an age study to take advantage of other ways of checking the reliability of the age measurements.The simplest means is to repeat the analytical measurements in order to check for laboratory errors.Over a thousand papers on radiometric dating were published in scientifically recognized journals in the last year, and hundreds of thousands of dates have been published in the last 50 years.Essentially all of these strongly favor an old Earth.Other objections raised by creationists are addressed in [Dalrymple2006a].

One question that sometimes arises here is how can scientists assume that rates of radioactivity have been constant over the great time spans involved.Also, as the authors of the 1968 article were careful to explain, xenoliths cannot be dated by the K-Ar method because of excess argon in bubbles trapped inside [Dalrymple2006].Thus in this case, as in many others that have been raised by skeptics of old-earth geology, the "anomaly" is more imaginary than real.Several hundred laboratories around the world are active in radiometric dating.Their results consistently agree with an old Earth.Radioactive decay rates have been measured for over sixty years now for many of the decay clocks without any observed changes.
