A total of 2128 calcitic and phosphatic shells, mainly brachiopods with some conodonts belemnites, were measured for their δ18O, δ13C 87Sr/86Sr values. The dataset covers the Cambrian to Cretaceous time interval. Where possible, these samples collected at high temporal resolution, up 0.7 Ma (one biozone), from stratotype sections all continents but Antarctica many sedimentary basins. Paleogeographically, are mostly paleotropical domains. scanning electron microscopy (SEM), petrography,...
Earth's surface chemical environment has evolved from an early anoxic condition to the oxic state we have today. Transitional between earlier Proterozoic world with widespread deep-water anoxia and a Phanerozoic large oxygen-utilizing animals, Neoproterozoic Era [1000 542 million years ago (Ma)] plays key role in this history. The details of Earth oxygenation, however, remain unclear. We report that through much later (<742 +/- 6 Ma), remained beneath mixed layer oceans; deeper water masses...

The environmental expression of sulfur compound disproportionation has been placed between 640 and 1050 million years ago (Ma) linked to increases in atmospheric oxygen. These arguments have their basis temporal changes the magnitude 34S/32S fractionations sulfate sulfide.

Abstract The Ediacaran–Cambrian interval was an eventful transitional period, when dynamic interactions between the biosphere and its physical environment allowed Earth System to cross into a new state, characterized by presence of metazoans, more equable climates expansive oxygenation oceans. Due retreat widespread sulphidic conditions, redox‐sensitive trace‐metals could accumulate greater extent in ‘black shales’ deposited localized anoxic/euxinic environments, such as highly productive...
Abstract Over the past few decades, Toarcian (Early Jurassic) black shale deposits of NW Europe have been extensively studied, and possible global regional mechanisms for their variation discussed. In this context, shales Northwest German Basin are still sparsely studied with regard to palaeo-depositional history. This study aims understand connection between influences on widespread Early oceanic anoxic event by examining two wells covering Upper Pliensbachian sediments in Northwestern...
