Isotopic evidence for changes in the zinc cycle during Oceanic Anoxic Event 2 (Late Cretaceous)

Abstract:

Widespread deposition of organic-rich shales during the Late Cretaceous Oceanic Anoxic Event 2 (OAE 2, ca. 94 Ma) occurred during a period of significant global paleo-environmental and geochemical change. It has been proposed that an increase in nutrient input to the ocean during OAE 2 was the key mechanism that generated and sustained high rates of organic-matter burial over time scales of 103–105 yr. Zinc is a bio-essential micronutrient and the proportion of Zn burial in oxic sediments rel...
