Historical succession of the Hauterivian stage defined in the Neuchâtel area (modified from Godet 2006). The main lithologies are briefly described. The evolution of microfacies is compiled from Blanc-Alétru (1995) and Godet (2006), following the nomenclature of Arnaud-Vanneau and Arnaud (2005). The different stratigraphic schemes (right-hand side of the figure) correspond to: 1 Thurmann 1835; 2 Desor and Gressly 1859; 3 Jaccard 1869; 4 Renevier 1874; 5 Baumberger 1901; 6 Remane 1989 (modified); 7 Arnaud-Vanneau and Arnaud 1990; 8 Clavel et al. 1995; 9 Godet et al. 2010, 2011, this work. Abbreviations of the names of the formations: CR Calcaire Roux, MA Marnes à Astieria, MBH Marnes Bleues d’Hauterive, MKZ Mergelkalk zone, PJN Pierre Jaune de Neuchâtel, MU Marnes d’Uttins, MR Marnes de la Russille
