For example, creationist writer Henry Morris [Morris2000, pg.

147] has highlighted the fact that measurements of specimens from a 1801 lava flow near a volcano in Hualalai, Hawaii gave apparent ages (using the Potassium-Argon method) ranging from 160 million to 2.96 billion years, citing a 1968 study [Funkhouser1968].

Technical details on how these dates are calculated are given in Radiometric dating. As with any experimental procedure in any field of science, these measurements are subject to certain "glitches" and "anomalies," as noted in the literature.

Here is one example of an isochron, based on measurements of basaltic meteorites (in this case the resulting date is 4.4 billion years) [Basaltic1981, pg. Skeptics of old-earth geology make great hay of these examples.

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.

Other objections raised by creationists are addressed in [Dalrymple2006a].

Whenever possible we design an age study to take advantage of other ways of checking the reliability of the age measurements.The use of different dating methods on the same rock is an excellent way to check the accuracy of age results.If two or more radiometric clocks based on different elements and running at different rates give the same age, that's powerful evidence that the ages are probably correct.Application of this method of age determination is limited to those periods of pottery and fired clay availability ( from about 6000 BC to the present).
