Absolute dating - Wikipedia

Three of the most clever techniques utilize uranium, volcanoes, and trapped electrons. Did you know that scientists can tell how old a cave painting is by dating the rocks on top of or underneath it? Like radiocarbon dating , Uranium-series U-series methods rely on radioactive decay. Scientists have learned how long it takes the above isotopes to decay: U has a half life the time it takes for half of a sample to decay of 4. Therefore, by measuring how much of the parent and daughter isotopes of uranium remain in a sample, scientists can determine how old it is.

Radiometric dating , radioactive dating or radioisotope dating is a technique which is used to date materials such as rocks or carbon , in 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 principles , radiometric dating methods are used in geochronology to establish the geologic time scale. By allowing the establishment of geological timescales, it provides a significant source of information about the ages of fossils and the deduced rates of evolutionary change.
