Geochronology

Geochronology is the science of determining the age of rocks, fossils, and sediments, using signatures inherent in the rocks themselves.

Def. the "science of dating samples of rock or sediment", any "one of the methods by which the age of different samples of rock can be determined" or the "division of ancient time into named subdivisions / periods" is called geochronology.
