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.

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.

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

None of these experiments has detected any significant deviation for any isotope used in geologic dating [Dalrymple1991, pg. Note, for instance, that light coming to earth from distant stars (which in some cases emanated billions of years ago) reflects the same patterns of atomic spectra, based in the laws of quantum mechanics, that we see today.

The isochron techniques are partly based on this principle.

The use of different dating methods on the same rock is an excellent way to check the accuracy of age results.

The differences actually found in the scientific literature are usually close to the margin of error, usually a few percent, not orders of magnitude!

Vast amounts of data overwhelmingly favor an old Earth.
