The age that can be calculated by radiometric dating is thus the time at which the rock or mineral cooled to closure temperature. Radiometric dating Conservation and restoration. Other events on earth can be dated equally well given the right minerals. This is understood and can be corrected for. All radioactive isotopes have a characteristic half-life the amount of time that it takes for one half of the original number of atoms of that isotope to decay. Harm to minors, violence or threats, harassment or privacy invasion, impersonation or misrepresentation, fraud or phishing, show more.

Uranium eventually decays into lead, and lead does not normally occur in zircon, except as the radioactive decay product of uranium. Harvard University Tutors. Brown University Tutors. Additionally, elements may exist in different isotopeswith each isotope of an element differing in the number of neutrons in the nucleus. Click Here to return to the search form.
