Chronological arrangement of stratified rocks
WebApr 14, 2024 · One of the most useful absolute dating methods for archaeologists is called radiocarbon dating. It works by measuring carbon isotopes, which are versions of the element carbon. All isotopes of carbon have 6 protons but different numbers of neutrons. Webrelative ages in rocks that are far apart fossils also provide a basis for stratigraphy independent of rock type (= biostratigraphy) William "Strata" Smith and Georges Cuvier: principle of faunal succession similar to principle of superposition • distinguished rocks on basis of fossil content • each assemblage of fossils represents a ...
