Radiodating equation

It is one of the simplest examples of a differential equation.

What radioactive materials actually do is decay according to a law: Decays/Time = K * Number of atoms K is a constant called the decay constant.

If a zircon crystal originally crystallizes from a magma and remains a closed system (no loss or gain of U or Pb) from the time of crystallization to the present, then the Discordant dates will not fall on the Concordia curve.

Sometimes, however, numerous discordant dates from the same rock will plot along a line representing a chord on the Concordia diagram. is then interpreted to be the date that the system became closed, and the younger date, t*, the age of an event (such as metamorphism) that was responsible for Pb leakage.

Since there is now only 1/4 of the original amount of Parentium-123, we know that two half-lives of Parentium-123 have elapsed.

But there are some questions that come to mind: Calculus students typically meet this problem somewhere in the second semester.

Another possible scenario involves U leakage, again possibly as a result of a metamorphic event.

This is the only way Parentium-123 decays, and there is no other source of Daughterium-123.
