Uranium—lead 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 from about 1 million years to over 4. The uranium—lead dating method relies on two separate decay chains , the uranium series from U to Pb, with a half-life of 4. These uranium to lead decay routes occur via a series of alpha and beta decays, in which U with daughter nuclides undergo eight total alpha and six beta decays whereas U with daughters only experience seven alpha and four beta decays. The existence of two 'parallel' uranium-lead decay routes U to Pb and U to Pb leads to multiple dating techniques within the overall U—Pb system. The term U—Pb dating normally implies the coupled use of both decay schemes in the 'concordia diagram' see below.
How Nuclear Radiation Works

The key difference between carbon dating and uranium dating is that carbon dating uses radioactive isotopes of carbon, whereas uranium dating uses uranium , which is a radioactive chemical element. Carbon dating and uranium dating are two important methods of determining the age of different organic materials. We call them isotopic dating methods. The oldest method among them is Uranium-Lead dating method. Although it is a very risky method, if we do it very carefully, the results are highly accurate. Overview and Key Difference 2.
RADIOMETRIC TIME SCALE
One of the oldest and most refined of the radiometric dating schemes. Technique which is 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. Radiometric dating technique based on analyses of the damage trails, or tracks, left by fission fragments in certain uranium-bearing minerals and glasses.
Three of the most clever techniques utilize uranium, volcanoes, and trapped electrons. Did you know that scientists can tell how old a cave painting is by dating the rocks on top of or underneath it? Like radiocarbon dating , Uranium-series U-series methods rely on radioactive decay.
