Radio metric dating.
heated during metamorphism
Radiometric dating is the principal source of information about the absolute age of rocks and other geological features, including the age of the Earth itself, and can be used to date a wide range of natural and man-made materials.
The four types of radiometric dating are: Potassium, Uranium, Rubidium, and Carbon I hope thats the answer you were looking for:)
Carbon 14 dating is the best known example of radiometric dating, but there are many others. Another example of radiometric dating is the dating of the age of geological formations on earth. The oldest known rocks on the earth that have been analyzed, have been dated back some 4.404 billion years.

by relative dating or radiometric dating
Radiometric measurement is based on the decay of certain elements, the rate of which is a known scientific fact.
According to radiometric dating the Earth is approximately 4.54 billion years old. This age is based on dating of meteorite material.
