Shallow and deep cycles connect Earth’s carbon reservoirs, but flow rates between them vary by many orders of magnitude. Currently the fastest process is anthropogenic transfer to the atmosphere during the production of energy and cement, annually transferring many gigatons of CO2 to the atmosphere and oceans at a rate that is unbalanced by slow CO2 recycling into the solid Earth. The aim of this session is to look at mineralogical aspects of carbon cycling and recycling, comparing natural and anthropogenic fluxes. We welcome studies at the interface between atmosphere, hydrosphere and lithosphere, including carbon isotopic signatures of natural materials as tracers of past global events and cycles. We also encourage contributions from the applied side of (bio)mineralogy, including out-of-the-box ideas pertinent to CO2 capture, storage, re-use and recycling, as well as potential methods to speed up the transfer back to the solid Earth.
