Relative dating, meanwhile, measures the order of past events, without determining their absolute age.

Absolute dating of rock is achieved by radiometric dating techniques.

Geologist determine the age of rocks using radioactive dating.For a single element, these atoms are called isotopes.Because isotopes differ in mass, their relative abundance can be determined if the masses are separated in a mass spectrometer ( Radioactive decay can be observed in the laboratory by either of two means: (1) a radiation counter (e.g., a Geiger counter), which detects the number of high-energy particles emitted by the disintegration of radioactive atoms in a sample of geologic material, or (2) a parent atoms.Our editors will review what you’ve submitted and determine whether to revise the article.Join Britannica's Publishing Partner Program and our community of experts to gain a global audience for your work!
