Geochronology is the science of determining the age of rocks, fossils, and sediments using signatures inherent in the rocks themselves absolute geochronology can be accomplished through radioactive isotopes, whereas relative geochronology is provided by tools such as palaeomagnetism and stable isotope ratios.
