a major achievement of geochronometry is the documentation of geologic time, as represented in geologic time scales. a geologic time scale is a scheme that integrates the geochronologic subdivisions of geologic time and their absolute ages and durations. the latest version of the geologic time scale was published in 2004, and includes a comparison of present and past time scales. the greater efforts of geochronometry today are aimed at retrieving accurate ages of major events in the earth's history and of stage/age boundaries.
