In addition to the ages of Earth, Moon, and meteorites, radiometric dating has been used to determine ages of fossils, including early man, timing of glaciations, ages of mineral deposits, recurrence rates of earthquakes and volcanic eruptions, the history of reversals of Earth's magnetic field, and the age and duration of a wide variety of other geological events and processes.

The rock is heated slowly, and at various times the molten portions are moved to the surface in a series of lava flows. A Radiometric Dating Resource List Tim Thompson has collected a large set of links to web pages that discuss radiometric dating techniques and the age of the earth controversy.
