Geochemical signatures of black shales deposited during Oceanic Anoxic Event 2 (Cenomanian/Turonian) in the tropical Atlantic (Demerara Rise, ODP Leg 207) and in northern Germany (Wunstorf
Diese Studie präsentiert eine anorganisch-geochemische Untersuchung von zwei Sedimentabfolgen des Ozeanischen Anoxischen Ereignisses 2 (OAE 2) unterschiedlicher paläogeografischer Standorte. Am Demerara Rise (ODP Leg 207; tropischer Atlantik) sind die Sedimente, die während OAE 2 abgelagert wurden, …

POPULATION DYNAMICS AND GEOCHEMISTRY OF BENTHIC AND PLANKTONIC FORAMINIFERA TO INTERPRET THE PALEOCEANOGRAPHIC CHANGES ACROSS THE CENOMANIAN-TURONIAN OCEANIC ANOXIC EVENT 2 AT LOW AND HIGH LATITUDES
… Earth’s history, namely the Cenomanian-Turonian Oceanic Anoxic Event 2 (OAE 2). It is globally marked by a positive δ13C excursion due to the deposition and burial of large amounts of organic matter in the ocean. The exact causes of OAE 2 are still studied but it is understood that it might be …

High precision U/Pb geochronology on the Cenomanian Dakota Formation, Utah : implications for paleobotany and the transgression of the Western Interior Seaway preceding Oceanic Anoxic Event 2
The Dakota Formation was deposited during the Cenomanian, a time when the Western Interior Seaway spanned much of North America. The Dakota Formation contains a rich record of plant and animal fossils. Key to understanding their importance, it is imperative to precisely place the Dakota Formation …

Cyclostratigraphy And Sedimentation Of The Cenomanian-Turonian Tuscaloosa Marine Shale
… rate, to identify and correlate the cretaceous oceanic anoxic event 2 (OAE 2) recovery period within the studied interval, and to determine the possible mechanisms of orbital forcing. Results from multitaper spectral analysis and average spectral misfit reveal multiple statistically significant …

U-Pb calcite dating of fossil eggshell and its impact on continental terrestrial sedimentology
… geochemical signature related to the Cretaceous Oceanic Anoxic Event 2, but nearly syndepositional uptake within the Tel Ulaan Chaltsai fossilized eggshells. In addition, Data Chapter 2 attempts to reinvestigate the sedimentological and geochemical aspects of Tel Ulaan Chaltsai to better place …
