Towards a palaeogeographical and sequential framework for the Givetian of Belgium

peer reviewed ; This paper starts with a review of facies and reef morphologies from the Givet Group in the Ardenne area. Platform initiation and evolution are analyzed and related to external factors at a global scale (sea level changes, climate changes), at a regional scale (local subsidence, change in detrital supply) and to internal factors like organic communities composition. More specifically, the location of reef barriers are related to sea level changes and a sequence stratigraphic canvas is proposed.
