For example, most people don't realize that carbon dating is only rarely used on rocks. A disagreement over the age of the Earth is relatively minor in the whole scope of Christianity; it is more important to agree on the Rock of Ages than on the age of rocks.

Thermochronological methods are related to this, and provide information on temperature histories.

Temperature increases with depth in the earth, and knowing the temperature history of a rock sample can thus provide information on how much erosion has taken place, how deep it was burried, and, for example, also what the potential for oil and gas in a particular geological horizon is.

There are over forty such techniques, each using a different radioactive element or a different way of measuring them.
