Dating uranium

dating uranium-87

With all radiometric dating processes, the accuracy of uranium-lead dating is called into question.

Like all radiometric dating methods, uranium-lead dating has a range that it works best.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.It also implies that none of the factors that might affect the rate of the radioactive decay could not. If the ages this dating process generates are true, it gets harder to assume that nothing on the outside of the sample has any effect on the system.After a few million or billion years of a near-closed system, it will have a large error.Other compounds that do not contain zirconium but are commonly used for this method are titanite, and monazite.

Since most radiometric daters prefer using zircon for this process, geologists often call uranium-lead dating zircon dating.

Assuming a closed system means that nothing on the outside of the rock affected the sample.

This means that none of the parent or daughter isotope leaked in or out.

Most radiometric daters prefer using zircon for these reasons, but it is not the only compound used for uranium-lead dating.

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

The last of the benefits is that the zircon, itself, is very hard.
