When combined with element geochemistry data, the interpretative power of GRS and/or MS for genetic stratigraphy greatly increases, as was demonstrated in several recent papers addressing the Devonian-Carboniferous boundary (Kumpan et al 2014a, b;Bábek et al 2016) and the Givetian-Frasnian boundary (Devleeschouwer et al 2015). The petrophysical record of the Fr-Fa boundary was discussed in several papers mostly providing data either on MS (e.g.…”

Rapid and profound changes in Earth surface environments and biota across the Frasnian-Famennian (Fr-Fa) boundary are well known and related to one of the five most severe mass extinction events in Earth history. Here, we present sedimentological, biostratigraphical, petrophysical (gamma-ray spectrometry, magnetic susceptibility) and geochemical (X-ray fluorescence) data from environmentally distinct sections in the Moravian Karst (Czech Republic) and compare them with the Steinbruch Schmidt section in the Kellerwald (Rheinisches Schiefergebirge, Germany). Both areas were located at the southern margin of Laurussia. The studied sections span the interval from the Lower or Upper rhenana to the Palmatolepis minuta minuta or younger conodont zones and the foraminiferal Eonodosaria evlanensis Zone and Eonodosaria evlanensis-Quasiendothyra communis Interzone including high resolution biozonation of the Fr-Fa boundary interval. In the Moravian Karst pure limestone facies of an inclined carbonate ramp reflect the worldwide trend in the widespread occurrence of calcimicrobes during upper Frasnian and lower Famennian. Geochemical and petrophysical data show a decrease in grain size of the siliciclastic supply and carbonate productivity in the Kellwasser Event intervals probably due to a deepening and correlate with maximum flooding surfaces and highstand system tracts in the Steinbruch Schmidt. Certain differences in some geochemical proxies between the Moravian Karst and Steinbruch Schmidt are due to lower carbonate dilution of the latter. Significant Zr, TiO 2 , Mn or Fe 2 O 3 enrichments may indicate the influence of volcanic sources in the studied Moravian Karst Fr-Fa sections.

“…Rapid global environmental changes in the Late Devonian led to major biotic crises at the Frasnian-Famennian (Kellwasser Event; Buggisch, 1991;Averbuch et al, 2005) and the Famennian-Tournaisian boundaries (Hangenberg Event; Bábek et al, 2016). Obviously, such drastic variations in paleoclimate also led to changing subaerial weathering conditions in the provenance area during Late Devonian/Early Carboniferous times, reflected by changes in clay mineralogy.…”

“…Whereas moderate chemical weathering typically results in illite-rich composition of sediments, kaolinite is a product of intense weathering under humid conditions (Rachold and Brumsack, 2001;Niebuhr, 2005). Furthermore, the clay mineral distribution within a mudrock strongly influences the K/Al ratio, with high ratios reflecting high illite contents, and dominance of smectite, chlorite or kaolinite resulting in low K/Al ratios (Bábek et al, 2016). K/Al ratios correlate well with illite/kaolinite ratios for samples that show an illite/kaolinite ratio up to 3.…”

The mineralogy of Devonian to Carboniferous shales from the Ukrainian Dniepr-Donets Basin (DDB) was investigated during this study. These shales show a high compositional variability in vertical and lateral directions. Furthermore, stratigraphic trends were found to be controlled both by climatic factors as well as by changing detrital input from the hinterland. High kaolinite contents and predominance of kaolinite over illite in the Tournaisian and partly in the lower Visean units are likely a result of intense chemical weathering related to the Hangenberg climatic event at the Devonian/ Tournaisian boundary. In contrast, abnormally high kaolinite contents in upper Visean and Serpukhovian samples at the basin center might be caused by different transport properties of kaolinite and illite, leading to selective concentration of small detrital kaolinite particles, which are often in the sub-micrometer range according to scanning electron microscopy observations. K/Al elemental ratios correlate well with illite/kaolinite ratios for samples in which significant amounts of both clay minerals are present, which enables a pre-evaluation of the relative kaolinite content based on bulk geochemical data. As kaolinite is suggested to decrease the fraccability of shales and to have a great influence on their wetting behaviour, this is useful information for explorational purposes. Higher feldspar contents in Devonian and Tournaisian samples, especially along the NE basin margin and in the shallow NW part of the DDB, are likely related to increased detrital input from magmatic precursors (e.g. in the Voronezh Massif ) during (and shortly after) the active rift stage of the DDB. In general, feldspar contents are higher in proximal positions compared to the basin center, which is likely a result of shorter transport distances of the comparably large feldspar grains. Finally, the presence of expandable clay minerals down to depths of 6 km and the fact that no thermal maturity trend is visible down to these depths, proves, that a low post-depositional heat flow was present in the DDB. This is in good agreement with vitrinite reflectance measurements and thermal modelling results from previous studies, which suggest a low Mesozoic heat flow.

ABSTRACT. The Rhenish Kulm Basin is a deeper-water foreland basin developing in front of the Variscan Orogen in Germany. Three major facies interfinger and might overwhelm the adjacent one in time. These are (1) internal siliciclastic flysch facies, (2) central starved basin facies, and (3) calciturbidite facies. Calciturbidites are derived from the Northwest European shallow-water carbonate platform or not preserved intrabasinal sources. Besides, a deep intrabasinal swell facies is characterized by condensed successions. Diagnostic rock types within each facies enable the recognition of systems tracts of third-order depositional sequences. The interpretation of faunal developments and bioevents support these attributions. Hence, for the first time a sequence stratigraphic subdivision of the Rhenish Kulm Basin into 13 sequences is achieved, ranging from the latest Devonian to the early Namurian. The lower nine sequences are correlated with the Dinantian sequences earlier established on the Belgium shallow-water platform. Two Brigantian sequences 10 and 11 are identified and, despite the prograding Variscan Orogen, the two lower Namurian (Pendleian, Arnsbergian) sequences 12 and 13. The results demonstrate the successful application of sequence stratigraphy in a deeper-water basin, show that sea-level changes overrule the general, more gradual tectonic development of the basin, and prove the Palaeotethyan, if not global isochroneity of Mississippian sequences.
