Absolute geochronology can be accomplished through radioactive isotopes, whereas relative geochronology is provided by tools such as palaeomagnetism and stable isotope ratios.

By combining multiple geochronological (and biostratigraphic) indicators the precision of the recovered age can be improved.

The dating method is usually performed on the mineral zircon.

Additional complications come from the burning of fossil fuels such as coal and oil, and from the above-ground nuclear tests done in the 1950s and 1960s.

and most refined of the radiometric dating schemes.

The amount of trapped electrons corresponds to the magnitude of the ESR signal.

Geochronology is the science of determining the age of rocks, fossils, and sediments using signatures inherent in the rocks themselves.
