Zhou is the longest-lasting first-class geological chronological unit in geochronology, which is equivalent to the formation time of a universe (first-class stratigraphic unit). The geological history since the formation of the earth can be divided into four periods: Phanerozoic (from the formation of the earth to 4 billion years ago), Archean (from 4 billion years ago to 2.5 billion years ago), Proterozoic (from 2.5 billion years ago to 5.4/kloc-0.0 billion years ago) and Phanerozoic (from 5.4/kloc-0.0 billion years ago).
