Caractérisation des déformations méso-cénozoïques et des circulations de fluides dans l'Est du Bassin de Paris

Abstract : The succession of different fracturing and fluid circulation events has been established for the Eastern part of the Paris Basin. Synsedimentary deformations in the Jurassic units, palaeostresses and fluid palaeocirculations are described on the basis of new field observations, drilling data and geochemical and isotopic analyses of diagenetic and tectonic materials. On the basis of the new decompaction data and the discovery of sedimentary dykes, an extension tectonic context is defined from the end of Dogger to the Malm. These early deformations fit in a general tectonic timetable, starting from the end of the Mesozoic to the present, and in which the palaeostresses relative to the Late Cretaceous to Tertiary tectonic stages have been integrated. A detailed study of bedding stylolites has confirmed their role during compaction as well as during later tectonic reactivation. Finally, analysis of the isotopic composition (δ18O and δ13C) of calcites from tension gashes and rocks provide important constraints on the origin and nature of the palaeofluids which circulated in the Paris Basin from Jurassic to Tertiary.
