For example, if all Phanerozoic volcanic arcs are palaeo-geographically delineated and reconstructed to their present-day locations, then some of them (from different geological time periods) will overlap in areas where subduction was pro longed, or where subduction-related magmatism repeatedly affected the same area of continental crust.

The tables typically focus on Phanerozoic time and identify the approximate dates of geological periods, but geological time before the Paleozoic era is usually identified as "Precambrian.
