A wide range of various proxies (e.g., mineralogy, organic carbon, inorganic geochemistry, C and Mo isotopes, framboidal pyrite) were applied for interpretation changing oceanic redox conditions, bioproductivity, the regional history magmatic activity. This resulted in internally consistent late Famennian Hangenberg Crisis subtropical deepest water sites epeiric Rhenohercynian Saxo–Thuringian basins, as well more open Paleo-Tethys Ocean. High mercury concentrations detected all studied...
Abstract The end-Devonian global Hangenberg event (359 Ma) is among the most devastating mass extinction events in Earth’s history, albeit not one of “Big Five”. This linked to worldwide anoxia caused by climatic changes. These changes could have been driven astronomical forcing and volcanic cataclysm, but ultimate causes still remain unclear. Here we report anomalously high mercury (Hg) concentration marine deposits encompassing from Italy Austria (Carnic Alps). recorded sections...
Recently, the end-Devonian mass extinction (Hangenberg Crisis, 359 Ma) was identified as a first-order extinction, albeit not one of "Big Five" events. Many marine and terrestrial organisms were affected by this crisis. The cause is still conjectural widely discussed. Here we report anomalously high mercury (Hg) concentrations from South Tian Shan (Uzbekistan), together with correlation using conodont biostratigraphic data. Hg enrichment (to 5825 ppb) detected in deposits encompassing...
Integrated biostratigraphical, microfacial and geochemical studies of the Lower Kellwasser Event in Płucki succession (southern Poland) provide details about redox conditions during deposition this horizon deep-shelf Łysogóry basin Holy Cross Mountains. The environment is characterized by calm sedimentation soft, muddy carbonate substrate. However, microfacies changing from wackestones to grainstones, presence crushed or current-oriented nautiloid shells occurrence redeposited material...
Abstract The mid-Tournaisian black radiolarian cherts of the Lydiennes Formation are exposed in deep-shelf successions Puech de la Suque and Col des Tribes sections Mont Peyroux Nappe area Montagne Noire, southern France. This interval represents anoxic event that is also termed Lower Alum Shale Event. associated with a global marine transgression was characterized by increased productivity drastic facies changes from pelagic carbonate sedimentation to widespread deposition organic-rich...
The provenance of top-Famennian sedimentary rocks linked to the Hangenberg Crisis from northern Rhenish Massif (Germany) was investigated by means detrital zircon U-Pb geochronology. Based on obtained age spectra, three main tectonothermal domains are recognized as possible sources: Paleo- and Mesoproterozoic (~ 2000–1000 Ma) units Baltica Early Paleozoic Caledonian orogen 500–400 Ma). Our interpretation detritus having been derived source areas, i.e., Scandinavian Caledonides, with a minor...
A positive carbon stable isotope excursion of about 3‰ is documented in the topmost lower Frasnian at Padberg, eastern Rhenish Massif, as a muted record worldwide early−middle isotopic perturbation (punctata Event; up to 6–8‰ shift both δ13Ccarb and δ13Corg elsewhere), comparable with Appalachian δ13C curve. This German signature occurs 12 m thick calciturbidite succession correlates well three-step chemostratigraphic pattern known from Holy Cross Mountains, Poland. It especially clear...
Two studied sections of the Frasnian-Famennian (F-F) boundary beds in western Thailand differ significantly their depositional and geochemical characteristics. The highly condensed, monotonous Mae Sariang (MS) limestone succession generally corresponds to event-chemostratigraphic pattern F-F biocrisis based primarily on German sections, brief anoxic episodes are identifiable trace-metal signatures (but neither organic-rich intercalations nor distinct volcanic signals). In case Thong Pha Phum...
Abstract A tephra-rich cherty-clayey Famennian succession within the major Brzeźnica olistostrome in Bardo Mountains, Central Sudetes, SW Poland, preserves a record of lost ocean later incorporated into Variscan orogenic belt. Fluctuating but mostly oligotrophic regimes and low primary production levels were influenced by weak up-welling below perennial oxygen minimum zone, which controlled interplay between biosiliceous siliciclastic deposition oceanic basin, with episodic deficiency. The...
Pyroclastic horizons are common in the middle–upper Famennian carbonate and siliceous successions located near Rhenohercynian margins of Laurussia Variscian Saxothuringian oceanic realm. We present a detailed geochronological, geochemical mineralogical study tuffites from three sites southern Poland: Holy Cross Mountains (Kowala), Kraków–Silesia monocline (Czatkowice, Dębnik anticline), Sudetes (Bardo, Bardo Mountains). Airborne volcanic ash Czatkowice was deposited on shallow platform,...
