The ratio of the amounts of U and Pb in a rock sample enables the age of the rock to be estimated using the technique of radiometric dating. U forms a decay chain in which it undergoes a sequence of 8 alpha and 6 beta decays:.
Both isotopes are the starting points for complex decay series that eventually produce stable isotopes of lead. Uranium-lead dating was applied initially to uranium minerals, e.
Different samples of zircon may have different concentrations of U and Pb initially. It is further theorized that since all isotopes of the same element are chemically identical, they should be removed in proportional amounts, forming a straight line on the concordia diagram, that crosses the concordia curve at both the crystallization and the contamination date.
Uranium-Lead dating is a radiometric dating method that uses the decay chain of uranium and lead to find the age of a rock. As uranium decays radioactively, it becomes different chemical elements until it stops at lead.
Uranium—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.
Radiometric dating or radioactive dating is a technique used to date materials such as rocks or carbon , in which trace radioactive impurities were selectively incorporated when they were formed. The method compares the abundance of a naturally occurring radioactive isotope within the material to the abundance of its decay products, which form at a known constant rate of decay.
