Continental weathering as a driver of Late Cretaceous cooling: new insights from clay mineralogy of Campanian sediments from the southern Tethyan margin to the Boreal realm

Geodynamic framework of Campanian Tethyan bauxites and the clay minerals of the studied sections at around 80 Ma (modified from Bárdossy and Dercourt, 1990; Jolivet et al., 2016). Location of the sites studied: [A] Adda-3 borehole; [C] Cbr-7 borehole; [F] Furlo - Upper Road section; [G] Gubbio - la Bottaccione section; [K] El Kef - El Djebil section; [P] Poigny borehole; [S] Stevns-2 borehole; [T] Tercis-les-Bains section. Name of the Campanian bauxites localities: (1) Alpilles (France), (2) Haut-Var (France), (3) Markusovce (Slovakia), (4) La Boissière (France), (5) Nurra (Sardinia), (6) Villeveyrac basin (France), (7) Bédarieux (France), (8) Tyrol Brandenberg and Salzburg (Austria), (9) Unterlaussa (Austria), (10) Sümeg (Hungary), (11) Halimba (Hungary), (12) Ihakut-Németbanya (Hungary), (13) Grméc Hill (Bosnia Herzegovina), (14) Jajce (Bosnia Herzegovina), (15) Grebnik (Kossovo), (16) Kücük Koras, Sebimlkoy (Turkey), (17) Payas, Islaye (Turkey), (18) Sohodol, Cimpeni (Romania), (19) Euboea Island (Greece).216
