Marne de Flize (France)

The Marne de Flize is a geologic formation in France . It preserves fossils dating back to the Toarcian stage of the Jurassic period.

Description

The finely bedded blue-grey shales contain limestone lenses up to one metre in thickness La Croisette. The Marne de Flize is referred to the early Toarcian (Tenuicostatum and Serpentinum zones according to Mouterde, 1980). It is therefore coeval with the Posidonia Shale of southern Germany.
