Abstract
We report results of some of the latest cutting-edge research on traditional (C, O, S, N, Sr) isotope stratigraphy and some newer isotope systems (e.g., B, Ca, Mo, Fe, Cr, N), and elemental or elemental ratio (e.g., V, Mo, Hg, Rb/K, V/Cr, Zr/Ti, Mg/Ca, Mn/Sr, I/Ca) stratigraphy. The latter, in parallel with isotope stratigraphy, could be used as potential tracer for glacial events, buildup of volcanic gases (e.g., CO2) during glaciations, role of volcanism in mass extinction, salinity variation, redox state of the ocean and atmosphere, and provenance, among other applications. This paper also presents review on studies that are broad in both space and time, highlighting chemical events from the Archean to the Cenozoic. Special attention is given to Paleoproterozoic and Neoproterozoic isotope chemostratigraphy and problems including the reliability of the use of carbon isotopes for Neoproterozoic stratigraphic correlation. Some attention is also devoted to the early Paleozoic, K–T boundary, and Paleogene climatic and biogeochemical changes in the light of isotope chemostratigraphic studies.
