The dating element

In this case, a valid age can still be obtained, provided that they remain within the rock.

Samples for dating are selected carefully to avoid those that are altered, contaminated, or disturbed by later heating or chemical events.The uncertainty in determining the slope is reduced because it is defined by many points.A second advantage of the method relates to the fact that under high-temperature conditions the daughter isotopes may escape from the host minerals.These isotopes did not come from radioactive decay in the system but rather formed during the original creation of the elements.In this case, it is a big advantage to present the data in a form in which the abundance of both the parent and daughter isotopes are given with respect to the abundance of the initial background daughter.
