geocronología

geocronología

A relative dating method based on the association of early human sites with changing features of the land, such as the advance and retreat of glaciers or the rise and fall of sea levels. When these events are well dated, geochronology could be considered a reliable calibrated relative dating technique. Associated evidence may be changes in the frequency of plant species measured by pollen count and other kinds of paleoecology evidence.
