Stratigraphic correlation dating

WebStratigraphic superposition and the identification of regionally or even globally synchronous events are thus crucial. Absolute dating is achieved by recognizing the effects of some time-dependent process in the geologic record. Such processes may result from seasonal cycles or from radioactive decay. WebHowever, biostratigraphic correlation is not necessarily time correlation. 4. Isotopic age determinations. Isotopic dating methods (U-Pb, Rb-Sr, K-Ar, Ar-Ar) based on the radioactive decay of certain parent nuclides at a rate that is constant and suitable for measuring geologic time provide an additional key to chronostratigraphy.
