The age of the deposit may be determined by measuring how much of the daughter has formed, providing that neither isotope has entered or exited the deposit after its initial formation.

This method can be used to determine the age of calcium carbonate materials, such as coral.

Although zircon ZrSiO 4 is most commonly used, other minerals such as monazite see: It has a half-life the amount of time it takes for the elements radioactivity to decrease by half of aboutyears. During the alpha decay steps, the zircon crystal experiences radiation damage, associated with each alpha decay. If the radioactive daughter is an isotope of uranium, it will dissolve in water, but to a different extent than the parent; the two are said to have different solubilities. Retrieved from " https:
