Radiometric datingradioactive dating or radioisotope dating is a technique used to date materials such as rocks or carbonin which trace radioactive impurities were selectively incorporated when they were formed. The method compares the abundance of a naturally occurring radioactive isotope within the material to the abundance of its decay products, which form at a known constant rate of decay. Together with stratigraphic principlesradiometric dating methods are used in geochronology to establish the geologic time scale.

Geologists often need to know the age of material that they find. They use absolute dating methods, sometimes called numerical dating, to give rocks an actual date, or date range, in number of years. This is different to relative dating, which only puts geological events in time order. Most absolute dates for rocks are obtained with radiometric methods.

It is not about the theory behind radiometric dating methods, it is about their applicationand it therefore assumes the reader has some familiarity with the technique already refer to "Other Sources" for more information. As an example of how they are used, radiometric dates from geologically simple, fossiliferous Cretaceous rocks in western North America are compared to the geological time scale. To get to that point, there is also a historical discussion and description of non-radiometric dating methods.

Archaeology is a subfield of anthropology, the study of humans. In archaeology, researchers investigate the past via the material evidence left behind. There are many different specialties within archaeology, based on location and how far back in time they want to study. There are prehistoric archaeologists studying the earliest evidence of humans of Earth, but there are also historical archaeologists studying artifacts from a more recent time with historical records.

The main difference between absolute and relative dating is that the absolute dating is a technique to determine the numerical age of a rock or a fossil whereas the relative dating is a technique that determines the relative age. Furthermore, absolute dating can be done with the use of radiometric dating while relative age is determined with respect to other layers. The four techniques used in absolute dating are radiometric dating, amino acid dating, dendrochronology, and thermoluminescence.
