Through the correlation of a ten of sections from platform to basin we suggest that the Cenomanian-Turonian Boundary Event and the deposition of black shales are at least in part linked to morphologic changes due to shallow-water carbonate production during a rise in relative sea-level, at first slow, faster later.
