Rb-Sr, Pb-Pb, and U-Pb. They use absolute courting methods, sometimes referred to as numerical dating, to give rocks an precise date, or date vary, in numbers of years. This is different to relative dating, which only puts geological events in time order.

The Cretaceous Period is noted for a number of carbon isotope excursions — such as the well-known Weissert Event, which recorded abrupt changes in atmospheric carbon dioxide (CO2) concentrations associated to international volcanic exercise. To learn the time on this radioactive clock, scientists use a device known as a mass spectrometer to measure the number of mother or father and daughter atoms. The ratio of parents to daughters can inform the researcher how old the specimen is. The more parent isotopes there are — and the less daughter isotopes — the youthful the sample.

Some of the isotopes used for this purpose are uranium-238, uranium-235 and potassium-40, each of which has a half-life of greater than a million years. The radioactive decay of any particular person atom is a totally unpredictable and random occasion. However, some rock specimens have an enormous number of radioactive isotopes, maybe trillions of atoms and this large group of radioactive isotopes do have a predictable pattern of radioactive decay. The radioactive decay of half of the radioactive isotopes in this group takes a particular amount of time. The time it takes for half of the atoms in a substance to decay known as the half-life.
