Neogene sedimentary formations are often poorly lithified, because they are young and generally have not been deeply buried. The Neogene Period is divided into two epochs: the Miocene and Pliocene. Miocene EpochAn epoch is the second smallest geochronologic unit, between a period and an age. It is the equivalent of a chronostratigraphic series. As of April 2022 there are currently 37 defined and one informal epochs/series. There are also 11 subepochs/subseries which are all within the Neogene and Quaternary. The Geologic Time Scale is divided into four eons, ten eras, 22 periods, and several epochs and ages. Each eon, era, period, and epoch is defined by major geological or paleontological events. The eons are the Hadean, Archean, Proterozoic, and Phanerozoic.
