Periods. Just as eons are subdivided into eras, eras are subdivided into units of time called periods.

At GSA you'll find the resources, confidence, and connections you need to reach fulfilling new heights in your geoscience career.Geologic Time Scale. Humans subdivide time into useable units such as our calendar year, months, weeks, and days; geologists also subdivide time. They have created a tool for measuring geologic time, breaking it into useable, understandable segments. For the purposes of geology, the “calendar” is the geologic time scale.

The primarily defined divisions of time are eons, the Hadean, the Archean, the Proterozoic and the Phanerozoic. The first three of these can be referred to collectively as the Precambrian supereon. Each eon is subsequently divided into eras, which in turn are divided into periods, which are further divided into epochs.Períodos de la era cenozoica. 01. de 03. períodos de la era cenozoica.
