SSP2.2 | Stratigraphy of hyperthermals
Stratigraphy of hyperthermals
Convener: Jacopo Dal Corso | Co-conveners: Joshua Davies, David Kemp, Piero Gianolla
Past hyperthermals (extreme climate warming events) offer crucial insights into the response of the Earth’s System to rapid and large-scale greenhouse gas emissions. In the geologic record, hyperthermals are studied using a number of sedimentological, palaeontological, mineralogical and geochemical proxies, which are used to constrain bio-geochemical models. In this multidisciplinary approach, the role of stratigraphy is always central. Constraining the ages of the studied rocks, understanding the timescales and associated uncertainties of changes observed at different locations, and correlating between marine and terrestrial strata are key and universal challenges. Addressing such challenges are, however, necessary pre-requisites for establishing the timing, pace and duration of hyperthermals, and understanding their likely causes.
In this session we invite talks on the stratigraphy of hyperthermals. We solicit oral presentations and posters on the lithostratigraphy, biostratigraphy, chronostratigraphy, magnetostratigraphy, sequence stratigraphy, chemostratigraphy and cyclostratigraphy of hyperthermal events. We particularly invite contributions that address open problems on global-scale correlation of palaeonvironmental and palaeobiological proxies from successions spanning major events such as the Permian–Triassic and the end-Triassic mass extinctions, the Toarcian and Cretaceous oceanic anoxic events, and the Palaeogene hyperthermals. Talks on the state-of-the-art and unconventional stratigraphic approaches are welcome, as are contributions on the technical aspects of various stratigraphic tools. We encourage early career scientists to present their work and offer their own fresh look to this long-standing, but still fundamental, aspect of the Earth Sciences.
