    Description: This dataset contains molybdenum, uranium, and rhenium concentrations; molybdenum isotope compositions; pertinent major element concentrations; and total organic carbon contents of black shales from the ~2 Ga upper Zaonega Formation, NW-Russia. The samples originate from drill cores OnZaP 1 and 3. This data was collected using (multi-collector) inductively-coupled plasma mass spectrometry, inductively-coupled plasma optical emission spectrometry, carbon analysis, and loss on ignition.

    Description: In order to advance our understanding of the emerging chromium (Cr) isotope system as a paleoredox proxy, we measured the 53Cr/52Cr of black shales deposited before, during, and after Cretaceous Oceanic Anoxic Event 2 (OAE2). We observed a 〉 1 per mil coherent negative 53Cr/52Cr excursion and significant drawdown in Cr enrichments during OAE2 coincident with a large positive carbon isotope excursion. Our observed negative 53Cr/52Cr excursion during OAE2 is most easily linked to an increase in the ratio of euxinic to reducing conditions. Additional work on other OAE sections is needed to determine the spatial significance of this Cr isotope trend.
