Download scientific diagram | Lignite and amber deposits from the Neau quarry. A. General view showing the Cenomanian lignites (CnL) in karsts incising the Cambrian limestones (Cmb); at the top of the quarry, Cenomanian glauconitic sands overlap both Cenomanian white sands (CnS) and Cambrian limestones. B. One Cenomanian karst showing at its top the contact between the lignites containing amber (CnL) and the glauconitic sands (CnG); the bag of the collector contains a large piece of fossil wood. C. Lateral view of a Cenomanian karst with the lignites (CnL) directly in erosive contact with the Cambrian limestones (Cmb) (photographs D. Néraudeau). from publication: Amber- and plant-bearing deposits from the Cenomanian of Neau (Mayenne, France) | A new Cenomanian amber-and plant-bearing deposit has been discovered at Neau, in the Mayenne department (France). The Cenomanian fossiliferous lignites are located in karst filling in a substratum of Cambrian limestones.
