Chronos (geologia)
Chronos geologicus, qui et chronozona stratigraphica, est gradus aevorum geochronologicorum. Gradus superior est aetas geologica qui et stadium stratigraphicum. Post inquisitiones Axel Blytt et Rogerii Sernander,[1] recentius e vestigiis paludis Lethrensis in Dania confirmatas,[2] series Holocaena in chronozonas quinque ordinari solet, videlicet Praeboreale ab anno fere 11 700 a.p., Boreale ab 10 000, Atlanticum (in "Atlanticum anterius" et "Atlanticum plenum" divisum) ab 9000 et 8000, Subboreale ab 5800, Subatlanticum ab 2500.
