Géométries et environnements de dépôt de l'Oxfordien de l'Est du Bassin de Paris

Abstract : The diversity of facies and depositional environments of the Oxfordian of Lorraine allowed to propose a new lithostratigraphic framework. The survey of field and subsurface data using facies sedimentolgy and sequential stratigraphy allowed to describe 13 transgressive-regressive depositional cycles between the Mariae zone and the Planula zone. The depositional systems evolved from a marl-limestone ramp deepening southward, to a reefal and/or oolitic carbonate platform and finally to a marl-limestone ramp deepening northward. Amplifications of high frequency relative sea level falls appear in transgressive context and coïncide with climatic changes. Thirteen oxfordian depositional cycles are inserted in 6 medium frequency transgressiveregressive cycles and floodings are contemporaneous with tectonic events. Those 6 cycles are inserted in a low frequency regressive transgressive cycle and accommodation minimum appear in the upper part of the Middle Oxfordian.
