Stratigraphical distribution of Givetian ostracods in the type-area of the Fromelennes Formation (Fromelennes, Ardennes, France) and their relationship to global events

Magnetic Susceptibility Record in Paleozoic Succession (Rhenohercynian Massif, Northern Europe) – Disentangling Sea Level, Local and Diagenetic Impact on the Magnetic Records

“…When we compare the microfacies and magnetic susceptibility evolution for the Givetian sequences in Belgium and France, parallel trends occur in time-equivalent deposits (Figure 8) although both areas are separated by nearly a 100 km. The similarities in χ and microfacies patterns agree with published data (Boulvain and Préat, 1986;Préat et al, 1987;Préat and Boulvain, 1988;Bultynck et al, 1991;Boulvain et al, 1995;Préat, 2006;Préat and Bultynck, 2006;Boulvain et al, 2009;Maillet et al, 2011;Maillet et al, 2013) and allowed us to correlate a series of sedimentological events between the southern and the western margin of the Ardennes Givetian platform. In addition, the correlation of shallowing and deepening trends confirmed the occurrence of barrier-reefs through the Middle-Late Givetian within the intermediate buried part of the platform and completed the stratigraphic and paleogeographic model proposed in Figure 23 in Boulvain et al (2009) (Figure 9).…”

Insights into a million-year-scale Rhenohercynian carbonate platform evolution through a multi-disciplinary approach: example of a Givetian carbonate record from Belgium

“…10). Based on this study and selected literature (Boulvain & Préat, 1986; Préat, Ceuleneer & Boulvain, 1987; Préat & Boulvain, 1988; Bultynck et al 1991; Boulvain et al 1995, 2009; Préat, 2006; Préat & Bultynck, 2006; Maillet, Milhau & Pinte, 2011; Maillet, Milhau & Dojen, 2013) we illustrate the geometry and the key depositional changes characterizing the Givetian platform in the Dinant Basin. A summary of our interpretations and the illustration of the palaeogeographic history for the Dinant Basin during early to late Givetian time, including southward–northward migration of reefal bodies, is shown in Figure 11.…”

Late Eifelian and Early Givetian ostracod assemblages from Wellin, Hotton and On-Jemelle (Ardenne, Dinant Synclinorium, Belgium). Paleoenvironmental implications

“…Such association has also been reported from the Givetian of the Holy Cross Mountains of Poland by Malec et al (1987), but only the stratigraphic value of this association was pointed out by these researchers. The climatic conditions were probably wet and warm during the Early Givetian and became very arid in the Late Givetian perhaps in relation to the Taghanic Biocrisis (House, 1985;Aboussalam, 2003) and that probably explains the absence of leperditicopids in the upper part of the Givetian, and in contrast the abundance of Cryptophyllus and Cavellina Maillet et al, 2013a). In reality, no evaporitic episodes are known in the Dinant Synclinorium before the Late Givetian (Préat and Rouchy, 1986).…”

“…Lethiers, 1984;Casier, 1987Casier, , 2008Casier and Préat, 2003;Casier et al, 2011Casier et al, , 2013Maillet et al, 2013a). Herein, ostracods in the Lomme, Hanonet and Trois-Fontaines formations exposed in four sections located in three quarries in the Dinant Synclinorium (Ardenne) are studied in order to complete their inventory across the Eifelian/Givetian transition in the type regions of these two stages, and before the Taghanic Biocrisis (House, 1985;Aboussalam, 2003).…”
