SSP4.6Phanerozoic marginal and terrestrial palaeoenvironments as archives of biotic and climatic change: records and proxy developments
|Convener: S. Robinson | Co-Conveners: U. Heimhofer , J. McElwain|
Although generally recognised as important components of the Earth system, marginal and terrestrial palaeoenvironments have, traditionally, presented a number of significant challenges to our ability to integrate them into our understanding of past climatic and biotic change in the pre-Quaternary. Critically, only these archives can provide us with information regarding the co-evolution of terrestrial environments and biota, and the relationship between climate and hydrological cycling. Furthermore, in addition to providing us with records of continental climates, terrestrial and marginal environments can inform our understanding of carbon cycling in the geological past. A fundamental difficulty in studying terrestrial and marginal strata has been the problem of stratigraphic correlation between marine and terrestrial records. A second challenge has been the use of terrestrial archives to provide quantitative palaeoclimatic and palaeoenvironmental reconstructions, across a range of lithologies and fossil preservation states. However, these challenges are being overcome through the use and development of new stratigraphic tools and palaeoclimatic proxy techniques. This session aims to explore these developments and their application to the Phanerozoic stratigraphic record. We welcome submissions that make use of stratigraphy, geochemistry, sedimentology, palaeontology, palaeobotany and/or climate modelling to understand the relationships between terrestrial climates, biotic and floral evolution and carbon-cycling.
