C. Durlet et Jp. Loreau, INHERENT DIAGENETIC SEQUENCE OF HARDGROUNDS RESULTING FROM MARINE ABLATION OF EXPOSURE SURFACES - EXAMPLE OF THE BURGUNDY PLATFORM, BAJOCIAN (FRANCE), Comptes rendus de l'Academie des sciences. Serie II. Sciences de la terre et des planetes, 323(5), 1996, pp. 389-396
Three types of inherent diagenetic sequences (IDS) of hardgrounds sepa
rating subtidal facies have been reported in the Bajocian limestones o
f the Seuil de Bourgogne. One type, including a meteoric diagenetic ph
ase but no vadose phase before overlapping, is interpreted as the resu
lt of marine ablation of exposure surfaces. Evidence is provided by th
e vertical distribution pattern of phreatic freshwater cements below t
he affected surfaces.
