| Abstract |
The authors recount the original definitions and the evolution of the conceptions of the Giuet Limestone and the Givetian at Givet. In order to end the existing confusion they define a Givet Group composed of three formations, which are, from base to top : Trois-Fontaines, Mont d'Haurs and Fromelennes Formations.Each of these formations corresponds to a third order positive-negative bisequence (marine facies - sabkha - marine facies), while second order sequences permit the recognition of thirty-two major phases which indicate the following environments : detrital and non-turbulent in the euphotic zone, reef, lagoon and of sabkha; minor first order sequences are recognized in those major phases.As for the Givetian, the authors make suggestions to be eventually examined by international bodies |
