WebMay 20, 2011 · Radiometric dating Most absolute dates for rocks are obtained with radiometric methods. These use radioactive minerals in rocks as geological clocks. The atoms of some chemical elements have different forms, called isotopes. These break down over time in a process scientists call radioactive decay. WebNumerical datingprovides a numerical age for a geologic feature or event. There are many methods of numerical dating that involve radioactive decay of naturally occurring elements. For example, the age of the Earth, approximately 4.6 billion years (or 4.6 Ga), has been determined using the decay of radioactive elements, such as uranium.
