The Mo, Tl, and U isotope paleoredox proxies: comparisons, contrasts, and future directions

Sedimentary molybdenum (Mo), thallium (Tl), and uranium (U) isotope ratios can potentially track global-scale changes to past ocean oxygenation levels. In this review we summarize and describe the unique strengths and weaknesses of these “paleoredox proxies”. We emphasize two cri...
