Presumably if all the world’s outcrops were integrated, sediments representing all of geologic time would be available for examination.

This optimistic hope, however, must be tempered by the realization that much of the record—older than 541 million years—is missing.

Correlating two separated outcrops means establishing that they share certain characteristics indicative of contemporary formation.
