definition: The Uranium-Lead (U-Pb) Dating is a method that encompasses several techniques that are employed in determining the geological age of both terrestrial and extraterrestrial (for example, meteorites) rocks. The method was first suggested by Boltwood in 1907 when he postulated lead to be the decay product of uranium. [Source: Encyclopedia of Anthropology; Uranium-Lead Dating]
