| Résumé : | Fifty-six ostracod species are recognized in the Hanonet Formation (Upper Eifelian) and in the lowermost Trois-FontainesFormation (Lower Givetian) of the Glageon Quarry (Southern border of the Dinant Basin, Avesnois, Northern France). The ostracods belong to the Eifel ecotype sensu Becker (in Bandel & Becker, 1975) and two assemblages are recognized: 1. assemblage III characterizes a relatively quiet marine environment below wave base on the mid-ramp setting (Hanonet Formation); 2. assemblage II characterizes a shallow marine environment above wave base on the inner-ramp (lower part of the Trois-Fontaines Formation). Comparatively with other outcrops from the Southern border of the Dinant Basin, the sea level fluctuations were of very low amplitude near the Eifelian/Givetian boundary at Glageon. The study of sediments in Glageon is consistent with the data from ostracods. © 1995. |
