Black shale deposition during Toarcian super-greenhouse driven by sea level [PDF]
Climate of the Past, 2013 One of the most elusive aspects of the Toarcian oceanic anoxic event (T-OAE) is the paradox between carbon isotopes that indicate intense global primary productivity and organic carbon burial at a global scale, and the delayed expression of anoxia in ...
