This article is about Age (geology). For other uses of the term Age , please see Age (disambiguation).
The age is the fundamental chronostratigraphic unit.
Being geochronologic units, ages represent a interval of geologic time. The corresponding chronostratigraphic units represent the body of rocks formed during the age, and are called stages
Ages/Stages are formally defined following the indications of the ICS (International Commission on Stratigraphy). More specifically, ages/stages are defined by the GSSP of their base, their top being defined by the GSSP of the overlying age/stage.
A list of ages/stages may be found at the International Commission on Stratigraphy.[1][2]
