Abstract
The Middle Callovian to Middle Oxfordian clay deposits drilled in the easte rn Paris Basin (borehole HTM 102, ANDRA) show a strong mineralogical change occurring in the lowermost Oxfordian (Scarburgense subzone, Mariae zone). Such a change probably results from the initial development of connections bem een the young Atlantic Ocean and the Paris Basin. A bentonitic lever id entified close to the boundary between Lower and Middle Oxfordian and also recognized in the subalpine Basin (South-East of France) at the same age, r eflects a volcanic activity probably resulting from an extensional regime: located in the North Sea.
