Tectonic Fluxes of Carbon DCO Workshop
Sunday Dec 8 2013 before AGU; Location in San Francisco (details soon)
Organizers: Jay Ague and Olivier Beyssac
We would like to invite you participate in a workshop at AGU on Sunday, Dec 8, sponsored by the Deep Carbon Observatory (DCO; https://dco.gl.ciw.edu/). The goal of the workshop is to develop a research initiative on Tectonic fluxes of carbon. As space is somewhat limited, please let us know by email if you will be able to attend and we will provide more details about the workshop.
The fluxes of carbon into and out of orogenic belts are probably the most poorly-constrained contributions to the global geologic carbon cycle. Is mountain building, for example, a net carbon source or sink? There is almost certainly no single (or simple) answer to such questions, and indeed the answers may vary depending on the time scale under consideration. This workshop aims to bring together workers in a diverse spectrum of fields to quantify sources and sinks of oxidized and reduced carbon as they relate to diagenesis, metamorphism, seismogenic zones and, ultimately, the return of carbon species to the shallow hydrosphere and atmosphere via gas/fluid phase transport or exhumation and erosion of mountain belts. How should we study these reservoirs and fluxes? What field areas would be "type localities" to elucidate processes?
We will have a full day of talks and discussion, and will provide breakfast and lunch. The preliminary schedule of events is:
