“…Böhm (1935) concluded an early Viséan age for the Lydiennes Fm, thus contributing to a lasting debate on a possible unconformity between upper Devonian and Viséan strata in southern France (see discussion in Boyer et al, 1968;1974). Coudray et al (1979), Engel et al (1982) and Lethiers & Feist (1991) reported from the succeeding Faugères Fm latest Tournaisian -early Viséan conodonts (from the anchoralis biozone onward), thus contradicting the assignment of Böhm (1935). The revised ammonoid data of Korn & Feist (2007) clearly show that the Lydiennes Fm does not contain any latest Tournaisian or early Viséan elements.…”

According to these conodont data the Tournaisian/Viséan boundary can be placed within the formation.…”

“…Engel et al (1982) provided the first correlation between formations from the Montagne Noire and the Rhenish Kulm Basin. Feist & Flajs (1987) and Lethiers & Feist (1991) added more details for specific time slices to this comparison. The decision (Paproth et al, 1991) to define the base of the Carboniferous in the La Serre section (global stratotype section and point, GSSP) has been a stimulus for the study of this time interval in the Montagne Noire from the mid-1980's onward.…”

ABSTRACT. The Kulm facies of the Montagne Noire formed in a foreland basin south of the French Massif Central. During the preorogenic phase (Tournaisian -early late Viséan) two major facies domains can be differentiated in the Montagne Noire. The Mont Peyroux Succession represents more distal environments with an almost continuous stratigraphical record, which displays the development from a deeper-water carbonate platform to a starved basin facies, which is followed by the onset of calciturbidite deposition. The contemporaneous Ecailles Succession, only found in exotic blocks, represents the proximal environments with important stratigraphical gaps. The synorogenic phase of the basin (early late Viséan -Serpukhovian?) is characterized by flysch deposits, which contain in the later stages large exotic blocks indicating the final collapse of a mixed-siliciclastic carbonate shelf system. Differences in the Kulm sequence of the Carboniferous foreland basin of southern France (Montagne Noire, Mouthoumet Massif and Pyrénées) are due to different local palaeotopographies and distances to platform areas and sediment sources in the preorogenic sedimentation, and the timing of the onset of the synorogenic sedimentation and the migration of the depocentre from east to west. Striking similarities in respect to the overall facies, but also to the development of particular facies during a particular time slice exist to the succession of the Rhenish Kulm Basin, especially its north-western part; e.g. dark shales with phosphatic nodules during the Lower Alum Shale Event or the interruption of the bedded chert deposition by deeper water carbonates during the latest Tournaisian -earliest Viséan.

A biostratigraphic correlation of the Devonian/Carboniferous (D/C) boundary sections from the Carnic Alps, the Graz Palaeozoic, the Montagne Noire and the Pyrenees resulted in a high-resolution record of the carbon isotopic composition of micrites (d 13 C carb ), of sedimentary organic matter (d 13 C org ) and of oxygen isotope ratios of conodont apatite (d 18 O phosph ). The studies focused on the interval between the Upper postera Zone (Late Famennian) and the sandbergi Zone (Lower Tournaisian). For the first time, weak but significant positive carbon isotope excursions in micrites and in the sedimentary organic matter is reported from the Middle and Upper expansa zones of the Carnic Alps. They coincide with a decrease in the oxygen isotope values of conodont apatite. The excursions indicate changes in the global carbon cycle during an episode of high seawater temperatures, and correlate with sedimentary change and a stepwise eustatic rise in the Rhenish Massif. High carbon isotope values were also measured in limestones from the Graz Palaeozoic in the Upper praesulcata Zone, which were previously reported from the Rhenish Massif, Carnic Alps, Montagne Noire and the North America continent. The change from a palmatolepid-polygnathid conodont biofacies to a palmatolepid-bispathodid-branmehlid biofacies in the expansa Zone in the Carnic Alps is obviously influenced by anoxic conditions and repeated transgressive phases. The protognathodids and the polygnathids start to radiate in the Upper praesulcata Zone, after the main end-Famennian extinction episode. This is connected with the disappearance of the palmatolepids, and environmental stress created by worldwide anoxic conditions, climate change and sea-level changes, stimulated the radiation of both protognathodids and the polygnathids. The regional correlation of the geochemical records as well as interpretations of these records on a global scale indicate that changes in conodont biofacies of Late Famennian-Early Tournaisian limestones were caused by a complex pattern of environmental changes.
