dating methods
dating methods During the last century geologists constructed a relative time scale based on
correlation of palaeontological and stratigraphic data. Depositional rates of
sediments have also been employed as a dating method, but only recently has absolute dating been made possible through the use of radioactive
isotopes. Of the various methods the last is obviously the most precise, but
fossils,
lithologies, and cross-cutting relationships do enable the geologist to give an approximate
relative age in field studies. See also
