Uranium-Lead dating is a radiometric dating method that uses the decay chain of uranium and lead to find the age of a rock. Sorry but they need to act, they were laughing hahahahah
Three-stage method during interpretation of uranium-lead isotopic data. Three-dimensional approach on the iterpretation of uranium-lead isoto e ratios arrive pnatural systems, development of which corresponds to three stages, has been painstaking. In the framework of the three-stage model two cases, differing in the character of uranium-lead systems violation on the activation of the third are discussed.
The primary case corresponds to uranium addition otherwise lead substraction, and the second equal - on the way to addition of lead of unknown isotopic content. Three-stage approach permits without amending the isotopic content of lead captured during crystallization to premeditated the start of the second also third stages of uranium-lead systems improvement and headed for evaluate neighborhood of pre-eminence added towards the practice.

Of all the isotopic dating methods in use today, the uranium-lead method is the oldest and, when done carefully, the most reliable.
Robert S. Krymsky; Moacir J. The procedures are applied to zircon, titanite, rutile, apatite, columbite-tantalite and whole rock.
Uranium-lead dating computes the age of the earth at 4. It is one of the oldest and most refined radiometric dating schemes, with a routine age range of about 1 million years to over 4.Porn Pics & Movies Uranium lead dating examples Showers 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. The dating method is usually performed on the mineral zircon. The mineral incorporates uranium and thorium atoms into its crystal structure , but strongly rejects lead. Therefore, one can assume that the entire lead content of the zircon is radiogenic , i.
