About this Research Topic
Recent advances in mass-spectrometry allows us to explore, together with the traditional C, O and Sr, several other isotopic systematics. Nd isotope ratios are progressively more used for paleoceanographic studies; B isotopes are increasingly used as proxy for ocean acidification, Hg isotopes are investigated to identify the role of volcanism on carbon cycle perturbations; Li and Mg isotopes are attracting increasing attention for paleoclimatic reconstructions and weathering; Ca isotopes are often investigated as a complementary tool to identify carbon cycle dynamics and perturbations as well as the carbonate saturation state of the past oceans. This Research Topic aims to provide the state of the art on isotope stratigraphy nowadays, as well as to identify the new frontiers that are emerging in this topic.
We believe that isotope stratigraphy is one of the most intriguing topics and powerful tools to unravel the complex processes that control Earth’s evolution and trigger global changes and their relationship with biotic evolution. This Research Topic aims to comprehensively explore its potential.
This collection aims to tackle isotope stratigraphy, from different perspectives, to return a comprehensive picture of this broad topic. We seek contributions focused on continental records (travertines, speleothems, paleosoils), as well as on shallow- and deep-water carbonates (from platform to pelagic records). Furthermore, contributions focused from the Paleozoic to the Present, at different time scales and stratigraphic resolutions, are more than welcomed. Long-term carbon cycle perturbations recorded in hundreds of thousands to millions of years, as well as decadal to centennial abrupt climate shifts would perfectly fit in this Research Topic. Furthermore, integrated isotope stratigraphic studies of non-conventional systematics applied to paleoceanography or to identify ocean acidification would be appreciated. Finally, contributions on new isotope species with possible applications in stratigraphic and paleoceanographic studies are strongly encouraged. In this framework, we welcome Original Research Articles as well as Reviews and Methodological papers.
We would like to acknowledge Dr. Alessandro Mancini has acted as coordinator and has contributed to the preparation of the proposal for this Research Topic.
