Abstract The worldwide recognition of the Toarcian carbon isotope excursion (T‐CIE) in organic‐rich sedimentary rocks has been linked to an oceanic anoxic event (OAE) which implies world's deep oceans were ∼183 Ma. majority independent redox observations used build this argument mainly obtained from T‐CIE sediments deposited on northern European epicontinental shelf. However, increasing evidence shown that shelf had limited connection with open ocean, making it unsuitable for reconstructing...
Abstract Marine sediments in glacially-carved fjords at high latitudes feature organic carbon (OC) burial rates, but there are fewer data on the role of glacial activity high-latitude OC rates outside fjords. Here, we investigate relationship between sediment deep troughs and basins southwest Greenland shelf Holocene dynamics. Since onset prominent Neoglacial advances ~2500 years ago, nature buried was influenced by glacier-driven increase accumulation (SAR), reactive iron (oxyhydr)oxide...
Abstract A Jurassic negative carbon isotope excursion (CIE), co‐evolved with Toarcian Oceanic Anoxic Event (OAE) at ~183 Ma, is suggested to be linked a global carbon‐cycle perturbation and well documented for terrestrial fossil woods marine sediments around the globe. theoretically coupled δ 13 C carb ‐δ org pattern due such dubbed event from CIE in Dotternhausen stratigraphic profile (southwest Germany) unexpectedly disturbed by two‐step decoupling which last step, upper order, of higher...
Abstract Vanadium hyper‐enrichment (V ≥ 500 μg g −1 ) is widespread in ancient marine organic‐rich sedimentary rocks and controlled by its source accumulation. To understand how V accumulation control hyper‐enrichment, the hyper‐enriched black shales of Late Devonian–Early Mississippian Bakken Formation (USA) were investigated here. The results imply that mainly derived from detritus open ocean. Its was always related to complexation V(IV) species organic matter and/or fine clay mineral...
Abstract Early Toarcian (~183 Ma) was marked by a global warming event which accelerated continental chemical weathering. To constrain the early weathering intensity of Cleveland Basin (Yorkshire, UK) region, this study employed its sediment proxies (potassium/aluminium (K/Al) and K/rubidium (K/Rb)). The K/Al K/Rb exhibit an anomalous signal from contemporaneous warm, moist world. Variations in for Yorkshire section inversely comply with detrital grain size changes (indicated Al/silicon...
