The oldest such minerals analyzed to date-small crystals of zircon from the Jack Hills of Western Australia-are at least 4.404 billion years old. įollowing the development of radiometric age-dating in the early 20th century, measurements of lead in uranium-rich minerals showed that some were in excess of a billion years old. This dating is based on evidence from radiometric age-dating of meteorite material and is consistent with the radiometric ages of the oldest-known terrestrial material and lunar samples. This age may represent the age of Earth's accretion, or core formation, or of the material from which Earth formed. ![]() The age of Earth is estimated to be 4.54 ± 0.05 billion years (4.54 × 10 9 years ± 1%).
