Uranium to lead dating

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.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.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.

After a few million or billion years of a near-closed system, it will have a large error.The last of the benefits is that the zircon, itself, is very hard.This fact helps with extracting the zircon out of the rock it was in.From what has been observed, even small amounts of rock metamorphosis should not disturb the elements in the zircon.Another benefit is that zircon has been found in most igneous rocks.
