Other radiometric dating techniques are available for earlier periods.

The half-life of potassium-40 is 1.3 billion years, far longer than that of carbon-14, allowing much older samples to be dated.

Potassium is common in rocks and minerals, allowing many samples of geochronological or archeological interest to be dated.

Argon, a noble gas, is not commonly incorporated into such samples except when produced in situ through radioactive decay.

The date measured reveals the last time that the object was heated past the closure temperature at which the trapped argon can escape the lattice.
