“…Transgression in the Late Permian has been suggested by Weidlich and Bernecker (2003). Baud et al (1996) recognized that high positive δ 13 C carb values during the Late Permian are closely correlated with the second-order transgressive regressive cycles and the third-order sequences.…”

High resolution carbon isotope analyses of carbonate and organic carbon from Meishan, South China showed that the variation of δ 13 C carb is marked by three large positive excursions during the Changhsingian (end-Permian). Carbon isotope stratigraphy during this stage shows three cyclic intervals in δ 13 C carb , with two cycles corresponding to the lower (Paleofusulinid minima Zone) and one corresponding to the upper Changhsingian (P. sinensis Zone). The large positive δ 13 C carb excursions indicate episodes of enhanced burial of isotopically light organic carbon, presumably in response to deep-water anoxia episodically extending into shallow water with the rise of sea level. The organic carbon during the Changhsingian is distinguished into two groups, and the δ 13 C org of each group parallels (separately) the more detailed profile of δ 13 C carb , strongly showing that the values of fractionation Δ 13 C cab-org remain relatively constant, with only two intervals with anomaly. The enhanced fractionation Δ 13 C cab-org with large negative δ 13 C org excursions apparently indicates significant inputs from sulfide-oxidizing bacteria and green sulfur bacteria, notably at bed 24 just predating mass extinction. Our evidence appears to support that the extended euxinic water is possible for the main pulse of mass extinction at the end-Permian.

“…Considering that the Guadalupian-Lopingian boundary interval represents a pronounced 2nd order lowstand of sea level (Weidlich and Bernecker, 2003), it is reasonable to assume that the onset of the transgression coincides with the base of Lopingian. The GuadalupianLopingian boundary most probably coincides with the sequence boundary.…”

“…2 and 3). Complete sequences consist of thin-bedded (0.05-0.7 m thick) transgressive systems tracts with grain-supported textures and thick-bedded (0.75-2.00 m) highstand systems tracts with mud-rich sediments representing increasingly restricted conditions (Weidlich and Bernecker, 2003).…”

“…The sediments were deposited in a subtidal to intertidal environment (Glennie et al, 1974). From a sequence stratigraphic point of view, stacked shallowing-upward high-frequency cycles prevail, which are often capped by subaerial exposure horizons (Weidlich and Bernecker, 2003). Despite intense dolomitization, relics of the primary textures have been preserved in the Mahil Formation.…”

The paleolatitudinal distribution patterns during Ladinian and Carnian time are characterized by an increasing expansion of reefs from the northern to the southern hemisphere. The optimum of reef diversity and frequency in the Norian is associated with the development of extended attached or isolated carbonate platforms. NorianRhaetian sponge and coral reefs of the Northern Calcareous Alps developed (1) as reef belt composed of patch reefs in platform-edge positions facing the open-marine northwestern Tethys basins and (2) as patch reefs in intraplatform basins as well as in ramp positions.Carnian and Norian-Rhaetian sponge and coral reefs of the Arabian Peninsula are formed (1) as reef complexes at the margins of carbonate platforms on the tops of volcanic seamounts in the southern Tethyan ocean, as small biostromes on these isolated platforms, and (2) as transgressive reef complexes on the attached platform of the Gondwana margin. The Norian Gosaukamm reefal breccia of the NW Tethys is a counterpart of Jabal Wasa reefal limestone of the Gondwana margin with similarities in geological setting and biotic composition. Rhaetian coral biostromes of low diversity known from the Austrian Koessen basin resemble to the time equivalent Ala biostromes of the isolated Kawr platform in the southern Neo-Tethys by forming a discontinuous layer in shallow intraplatform basin setting.
