helium dating

Englisch - Englisch

Definition von helium dating im Englisch Englisch wörterbuch

a method of determining the age of rock that depends on the production of helium during the decay of various radioactive isotopes of uranium and thorium

Method of dating that depends on the production of helium during the decay of radioactive isotopes of uranium and thorium. Because of this decay, the helium content of any mineral or rock capable of retaining helium will increase during the lifetime of that mineral or rock, and the ratio of helium to its radioactive progenitors then becomes a measure of geologic time. Fossils may also be dated by helium dating. The relatively large amount of helium produced in rocks may make it possible to extend helium dating to rocks and minerals as young as a few tens of thousands of years old
