Sažetak
Authigenic trace metal enrichments, as well as Mo and U isotope systematics, have attracted attention as a tool for reconstruction of ocean redox structure through Earth’s history. However, the main controls on such redox proxies need to be verified in modern analogues of past ocean environments. Due to the highly oxygenated modern atmosphere, analogues for ancient anoxic oceans are rare, particularly for times when conditions were likely to be enriched in dissolved iron. We have measured the Mo and U isotopic composition in tributaries, sediments, water column and sinking particles in a meromictic and ferruginous lake (Lake Pavin, France) to understand the behaviour of U, Mo and their isotopes in an environment akin to the Precambrian ocean.
