Radiometric dating is a means of determining the age of a mineral specimen by determining the relative amounts present of certain radioactive elements by age we mean the elapsed time from when the mineral specimen was formed radioactive elements decay (that is, change into other elements) by. The oldest rocks on earth, found in western greenland, have been dated by four independent radiometric dating methods at 37-38 billion years rocks 34-36 billion years in age have been found in southern africa, western australia, and the great lakes region of north america.

Radioisotope geochronology in its present form is made possible by radioactive decay radioactive decay, also known as nuclear decay or radioactivity, is the process through which the radioactive (unstable) nucleus of an atom emits particles which lowers it to a lower energy state. How does radiometric dating work has been conventionally dated as late triassic by the apparently successful application of radioisotopic dating techniques.
