Uranium to lead dating
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.
From what has been observed, even small amounts of rock metamorphosis should not disturb the elements in the zircon.
Some of the classic problems with this kind of dating process include what the process can really date, how far the radiometric process can date accurately, and the assumptions taken so the dating process works.The benefits of using zircon is that the trapping temperature is 900 C.This temperature makes the zircon hard to pull out substances out of it.The three main parameters that have to be set are the original amount of uranium and lead in the sample, the rate at which uranium and lead enter and leave the sample, and how much the rate of decay changes.Uranium-lead dating uses four different isotopes to find the age of the rock.
