a technique used to date materials such as rocks or carbon

radiometric dating method

nuclides predating the Earth's formation (found on Earth)

type of radiometric dating

radiometric dating method based on the degree to which secular equilibrium has been achieved between the parent U-234 and the daughter Th-230

method of radiometric dating

characteristic set of ratios of stable or unstable isotopes

radiometric dating technique for rocks and minerals based on the quantities of specific isotopes of rubidium (⁸⁷Rb) and strontium (⁸⁷Sr, ⁸⁶Sr)

isotopes that are produced by interaction of cosmic rays with the nucleus of the atom

radiometric dating technique based on analyses of the damage trails, or tracks, left by fission fragments in certain uranium-bearing minerals and glasses

includes rocks over 4 billion years old from the Hadean Eon

radiometric dating method useful for determining ages of rocks and meteorites

Thermochronologists use radiometric dating along with the closure temperatures that represent the temperature of the mineral being studied at the time given by the date recorded to understand the thermal history of a specific rock, mineral, or geologic unit. It is a subfield within geology, and is closely associated with geochronology.
