WebCarbon dating (also called carbon-14 or radiocarbon dating) is a method of determining the age of an organic substance by looking at the concentration of carbon-14. Isotopes are different forms of the same element that have a different number of neutrons. Carbon-14 is a radioactive isotope. Carbon-14 is produced in Earth's atmosphere. WebUranium–lead dating, abbreviated U–Pb dating, is one of the oldest and most refined of the radiometric dating schemes. It can be used to date rocks that formed and crystallised from about 1 million years to over 4.5 billion years ago with routine precisions in the 0.1–1 percent range. The method is usually applied to zircon.
