Abstract
The study of hydrofractured chalks of the Omey area (Paris Basin, Fran ce) revealed that hydrofracturing is a tectonic deformation with a hig h diagenetic potential In this geographic area, hydrofracturing activa ted by a modification of the stress state at constant fluid pressure i nduced important modifications of the pore network, the nannofacies an d the Sr content of the chalk. These diagenetic transformations result from a solution-deposition deformation that induced important mass tr ansfers. The high diagenetic potential of hydrofracturing is due to th e presence of interstitial fluids that activated and directed the mass transfers.
