STRATIGRAPHIC CONTROL UPON DEPOSITIONAL F ACIES, GEOMETRIES AND PROFILES ACROSS THE BATHONIAN-CALLOVIAN CARBONATE PLATFORM IN BURGUNDY

The stratigraphic record is the result of relative sea-level changes w hich depend on the sedimentary flux (sediment supply and local product ion), and on the accommodation potential. In carbonate sequences, the sedimentary flux is driven by environmental and hydrodynamic factors t hat control production and removal of carbonate material. This specifi city originates a number of additional problems in stratigraphic analy sis (i.e. genetic stratigraphy), compared to siliciclastic sequences. The paper aims al defining a method for correlating carbonate shelf se quences through the example of the Bathonian-Callovian Burgundy shelf. Maximum flooding surfaces are characterized and their correlation are constrained by independent biochronological data. This example helps to evaluate the influence of the stratigraphic control upon the variab ility of depositional profiles, and makes the prediction of carbonate reservoir geometries possible.
