Dear colleagues,

The Goldschmidt conference will be held in Paris this year (August 13-18 ; Please consider submitting an abstract to the session 'Organic Geochemistry of the Anthropocene – From Stratigraphy to Earth System' (Session 11i in Theme Environmental Geochemistry). Abstract submission is open until April 1st.

Convenors: Jagos Radovic, Christopher Reddy, Jérémy Jacob, Nathalie Dubois

Keynote: Mélanie Roffet-Salque (OGU - Bristol University - UK)

The Anthropocene has recently been proposed as a new geological epoch, in which human activities, such as the burning of fossil fuels, plant cultivation, soil erosion, and others, have modified the natural cycles of organic matter (OM). In addition to perturbing the cycling of natural OM and compounds, human activities released large quantities of diverse synthetic materials into the environment, which constitute multiple threats. The evolution of these complex transitions, since prehistory to the great industrial acceleration of the modern era, are reflected in equally intricate (bio)geochemical signals. In this session, we welcome contributions that address the source, fate, history, and ecosystem impacts of OM perturbations and compounds (natural and synthetic) that were released in the geological realm by human activities. In this context, showcases of novel, multidisciplinary approaches are particularly encouraged. The objective is to gather a diverse group of researchers, including archaeologists, paleoenvironmentalists, microbiologists, environmental geochemists, and others, who study the anthropogenic impacts in various media, and across temporal scales, using bulk, elemental, isotopic and molecular analyses. The session will aim to reevaluate the established (bio)geochemical concepts in relation to global change, and discuss possible solutions to alleviate the major environmental challenges presented by the Anthropocene.

Best regards, Nathalie, Jagos, Chris and Jérémy
