TLDR
Stable isotope analyses of carbonate and total organic carbon (TOC; δ13Corg) together with geochemical analyses of 54 major, minor, and trace elements and magnetic susceptibility measurements were carried out on whole rock samples of the undisturbed Permian-Triassic (P/Tr) limestone boundary sequence in the Idrijca Valley (W. Slovenia) as mentioned in this paper.About:

Journal ArticleDOI
Carbon-isotope stratigraphy across the Permian–Triassic boundary: A review
Christoph Korte,Heinz W. Kozur +1 more
TL;DR: The negative carbon-isotope excursion was most likely a consequence of a combination of different causes that may include: (1) direct and indirect effects of the Siberian Trap and contemporaneous volcanism and (2) anoxic deep waters occasionally reaching very shallow sea levels as discussed by the authors.
Journal ArticleDOI
Large shifts in the isotopic composition of seawater sulphate across the Permo–Triassic boundary in northern Italy
TL;DR: Carbonate-associated sulphate (CAS) extracted from a Permo-Triassic succession at Siusi in northern Italy is shown to preserve a true seawater-sulphate isotope record.
Journal ArticleDOI
Patterns of Phanerozoic carbonate platform sedimentation
TL;DR: In this article, the authors show that carbonate platforms changed substantially in spatial extent, geometry, composition and palaeogeographical distribution through the Phanerozoic, and that the combined global size of carbonate platform shows no significant decline through the phaneroozoic, suggesting that availability of tropical shelf areas was not a major control of platform area.

Carbon, sulfur, oxygen and strontium isotope records, organic geochemistry and biostratigraphy across the Permian/Triassic boundary in Abadeh, Iran
Christoph Korte,Heinz W. Kozur,Michael M. Joachimski,Harald Strauss,Ján Veizer,Lorenz Schwark +5 more
TL;DR: In this paper, the authors argue against the conclusion of Heydari et al. (2001) that the carbon isotope event at the P/T transition is an alteration artefact and not a global signal.

Early Triassic carbon isotope excursions from South China: proxies for devastation and restoration of marine ecosystems following the end‐Permian mass extinction
TL;DR: Early Triassic carbon isotopes are measured based on 1422 carbonate bulk samples from 10 Lower Triassic sections in different palaeogeographic settings in South China as mentioned in this paper.

The continental crust: Its composition and evolution
TL;DR: In this paper, the authors describe the composition of the present upper crust and deal with possible compositions for the total crust and the inferred composition of lower crust, and the question of the uniformity of crustal composition throughout geological time is discussed.
Journal ArticleDOI
Anoxic Environments and Oil Source Bed Genesis
TL;DR: The anoxic aquatic environment is a mass of water so depleted in oxygen that virtually all aerobic biologic activity has ceased as discussed by the authors, where the demand for oxygen in the water column exceeds the supply.
Journal ArticleDOI
Reactive iron in marine sediments
TL;DR: It appears that distinct microenvironments may exist in marine sediments, where, in one microenvironment, sulfide reacts with Fe oxides locally precipitating Fe sulfide minerals, and in another, Fe reduced and solubilized by microorganisms migrates freely into solution.
Journal ArticleDOI
Oceanic Anoxia and the End Permian Mass Extinction
TL;DR: Data on rocks from Spitsbergen and the equatorial sections of Italy and Slovenia indicate that the world's oceans became anoxic at both low and high paleolatitudes in the Late Permian, which may have been responsible for the mass extinction at this time.
Journal ArticleDOI
Rhenium and molybdenum enrichments in sediments as indicators of oxic, suboxic and sulfidic conditions of deposition
TL;DR: In this article, the authors present sedimentary Re and Mo data from box-and multi-cores spanning a range of redox conditions, from well-oxygenated sites to locations with substantial sulfide concentrations.
