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 radioactive dating diagram


Uranium—lead dating , abbreviated U—Pb dating , is one of the oldest [1] and most refined of the radiometric dating schemes. It can be used to date rocks that formed and crystallised [2] from about 1 million years to over 4.

Uranium lead radioactive dating diagram


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.
