Two isotopic techniques are commonly used, of which isotope dilution thermal. More ancient rocks can be dated by measuring the amount of decay of radioactive elements which may be present and is generically known as radiometric dating. The temperature at which this happens is known as the closure temperature or blocking temperature and is specific to a particular material and isotopic system.

Deep time Geological history of Earth Geological time units. Can geologists use radioactive dating to find the age of sedimentary layers? This means that if the amounts of C and N in a sample are known, then its age can be calculated for a wide range of years.

This transformation may be accomplished in a number of different ways, including alpha decay emission of alpha particles and beta decay electron emission, positron emission, or electron capture. Relative dating is used to determine the relative age of rocks. The proportion of carbon left when the remains of the organism are examined provides an indication of the time elapsed since its death.
