So, we rely on radiometric dating to calculate their ages. See more words from the same year. Helium is relatively abundant in many minerals, all of which are radioactiveand contain uranium or thorium as important constituents. Radiocarbon dating method confirmed that the Bosnian Pyramid of the Moon was built about ten thousand years ago! Holt McDougal Introduction to Geography: Radiometric dating is used to estimate the age of rocks and other objects based on the fixed decay rate of radioactive isotopes. Uranium-lead dating can be used to find the age of a uranium-containing mineral.

Examples of “radiometric dating”
Definition of radiocarbon dating. These examples are from the Cambridge English Corpus and from sources on the web. Principles of Radiometric Dating. Plate Tectonics. A scientist can take a sample of an organic material when it is discovered and evaluate the proportion of carbon left in the relic to determine its age.
