Notice that an absolute (numerical) age has been assigned to the beginning of each eon, era, period, epoch and age. These have been determined by a variety of methods, the most common of which is the radiometric dating of igneous rocks. The period is the basic unit of geological time in which a single type of rock system is formed. Two or more periods comprise a geological Era. Two or more Eras form an Eon, the largest division of geologic time. Some periods are divided into epochs. The major periods in the geologic history of the Earth are (mya=million years ago): EON.
