3 components in construction of scale: Stratigraphic scale (relative time) Chronometric scale (absolute ages) Calibrate the stratigraphic scale. Precambrian time scale mainly chronometric (i.e. radiometric). Not much “stratigraphy” left. Time scale hierarchy: eon (e.g. Phanerozoic, Archean), era (e.g. Paleozoic, Mesozoic, Cenozoic),
