Methane-Derived Carbonates
Methane-derived authigenic carbonates are the main by-products of methane alteration in the seafloor subsurface.
We investigate their role as a record of past and present methane discharge.
Despite the understanding of methane-derived carbonates increased in the last decade, the details of their formation remain poorly solved. How do the processes involved in their precipitation respond to variations of methane flux associated with environmental changes? How can we better use the biogeochemical signatures recorded in the carbonates to interpret variations in fluid composition over time?
