Annual Review of Nuclear Science. The age that can be calculated by radiometric dating is thus the time at which the rock or mineral cooled to closure temperature. By contrast, crustal destruction occurs at the margins of two colliding continents, as, for example, where the subcontinent of India is moving secimentary over Asia.
