Uranium 238 dating process

Some other compounds used that have zirconium are zirconolite, and badeleyite.

Other compounds that do not contain zirconium but are commonly used for this method are titanite, and monazite.

As uranium-238 decays into lead-206, it will sometimes decay into a different isotope of its parent uranium isotope and sometimes it will decay into an isotope of a totally different element than its parent.

This series of alpha and beta decays is known as the uranium-238 decay series..

Most radiometric daters prefer using zircon for these reasons, but it is not the only compound used for uranium-lead dating.This temperature makes the zircon hard to pull out substances out of it.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.One assumption is to use a worldview that uniformitarianism is accepted Where is the time from starting point, the original amount of uranium, the amount of uranium at the measurement, the original amount of lead, the amount of lead at the measurement, the rate uranium changes to lead, the average rate of loss and gain in the amount of lead, the average rate of loss and gain in the amount of uranium..This diagram has been made by using the ratio of uranium to lead of all the rocks dated with this method and their assumed age.Scientists know that there are geological events that can disturb the zircon and release the lead created from the uranium. To try to account for this, a radiometric dater will use many different samples and use the ones that fit the Concordia curve.Since most radiometric daters prefer using zircon for this process, geologists often call uranium-lead dating zircon dating.With all radiometric dating processes, the accuracy of uranium-lead dating is called into question.As uranium decays radioactively, it becomes different chemical elements until it stops at lead.The reason for stopping at lead is because lead is not radioactive and will not change into a different element.
