“…The well-known massive Carboniferous greywacke and flysch deposits clearly post-date the "Liegender Alaunschiefer" and its equivalents (Timmermann 1974). High, lethal ocean temperatures and a low latitudinal temperature gradient are not in accordance with Late Devonian to Early Carboniferous climate data: the oxygen isotopic evidence and the discovery of tillites indicate global cooling, with local glaciation in the southern hemisphere (Brand 1992;González-Bonorino 1992). Consequently, we propose that the stagnant ocean OAE model discussed for the Frasnian/ Famennian boundary by Joachimski and Buggisch (1993) is not applicable to late Tournaisian "Liegender Alaunschiefer".…”

This study reports the results of interdisciplinary investigations of Tournaisian deposits from the German Rheinisches Schiefergebirge and provides a genetic and sequence stratigraphic interpretation. Microfacies and geochemical data confirm normal marine outer shelf to slope environments for the Lower Tournaisian Hangenberg Formation. In contrast, data from the condensed, phosphatic "Liegender Alaunschiefer" black shale indicate low current energy and anoxic conditions in the sediment and the water column. We suggest that anoxia was caused by eutrophication and high organic productivity due to factors such as upwelling, a climaterelated improvement of oceanic ventilation, and volcanic nutrient input. The Hangenberg Formation represents the lowstand through the early transgressive systems tract of a third-order depositional sequence, while the "Liegender Alaunschiefer" is a late transgressive systems tract and maximum flooding deposit. The Richrath Limestone was deposited during the highstand systems tract. Thus, quickly rising sea level and eutrophication may account for the peculiar and uniform facies of the "Liegender Alaunschiefer".

“…Revived oceanic circulation in consequence of increased latitudinal temperature gradients (Berry and Wilde 1978) is consistent with the Tournaisian climate indicators (Brand 1992;González-Bonorino 1992) and may have had additional impact on the oceanic nutrient distribution.…”

“…The third major positive excursion and relatively high δ 13 C values from late Visean to Serpukhovian coincide with the Lowstand System Tract (LST) deposits in South China, glacio-eustasy sequences in Nevada [46], and extensively distributed glacial deposits [7,9,18], marking the onset of Permo-Carboniferous Glacial Maximum.…”

“…Ice rafted sediments and tillites have been recognized extensively from the Visean, Serpukhovian, and Bashkirian in South America, Australia, and Tibet of China [7][8][9][10]. Because of a lack of precise paleontological control and the erosion of initial glacial deposits by subsequent glacial advance [11], the best methods of assessing glaciation during late Paleozoic may be based on the glacio-eustatic change and carbon and oxygen isotopic records in low latitudes, rather than on direct study of glacial sediments.…”

“…A series of events occurred, such as the rise of vascular land plants [1], addition of organic carbon reservoir, drift of Gondwana [2], and the collision between northern Africa and Laurussia [3], which may produce the changes of global ocean currents circulation system and heat transport system [4]. These are thought to have brought about the lowering of atmospheric P CO 2 and glaciation during the Carboniferous [5][6][7][8][9][10].…”

Studies on carbon isotopes of bulk carbonates from Longan and Baping sections of Lower Carboniferous in Guangxi of China show that the stable carbon isotope compositions in carbonate rocks of the isolated platform and deep slope facies were resistant to the influence of early meteoric diagenesis and late burial diagenesis. Three major positive carbon isotope excursions have been recognized in Lower Carboniferous in South China. The first major positive δ 13 C shift of 4.19‰ occurred in the middle part of Siphonodella isosticha-upper Siphonodella crenulata zone (Tournaisian); the second with an amplitude of 4.65‰ occurred near the Tournaisian/Visean boundary; and the third of 2.23‰ in the lower part of Gnathodus bollandensis zone. The three positive shifts of δ 13 C can be correlated with global carbon isotope excursions and are consistent with the fall in global sea level, indicating that abundant organic carbon burial, lowering of atmospheric CO 2 , and glaciation may have occurred during these time intervals.
