Information - SSP17/BG11/CL47 Environmental perturbations during the Palaeozoic-Mesozoic interval: Organic geochemical and palynological proxies (co-organized by BG & CL)
The objective of this session is the reconstruction of palaeoenvironmental change in the marine and terrestrial biosphere by integrating organic geochemical and palynological techniques. Major environmental perturbations documented in the Palaeozoic and Mesozoic sedimentary record are often associated with prominent changes in terrestrial vegetation patterns, marine productivity, phytoplankton and microbial communities as well as in organic carbon burial and preservation. The composition and distribution of sedimentary organic matter is a sensitive recorder of these changes and allows to trace changes in palaeoclimatic and palaeoceanographic evolution as well as in ecosystem structure and biogeochemical cycling across critical intervals on different time-scales during the Palaeozoic and Mesozoic Era. To better understand the causes and consequences of palaeoenvironmental change we encourage contributions from different subdisciplines studying sedimentary organic matter from various perspectives including stable isotope and biomarker studies, palynofacies and maceral analyses as well studies with focus on spore-pollen and marine palynomorph assemblages. The high potential of such integrated analyses will benefit from the dialog between the various disciplines. Thus, we welcome all colleagues to contribute to this session for a broad scientific exchange and discussion.
