Multiple negative molybdenum isotope excursions in the Doushantuo Formation (South China) fingerprint complex redox-related processes in the Ediacaran Nanhua Basin
Ostrander, Chadlin; Swapan, Sahoo; Kendall, Brian; Jiang, Ganqing; Planavsky, Noah; Lyons, Timothy; Nielsen, Sune; Owens, Jeremy; Gordon, Gwyneth; Romaniello, Stephen; Anbar, Ariel (Elsevier, 2019-09-15)The Ediacaran Doushantuo Formation offers one of the most complete and extensively studied records of end- Neoproterozoic biotic and environmental change. Here, we report multiple coeval negative molybdenum (Mo) ... -
Technical comment on “Reexamination of 2.5-Ga ‘whiff’ of oxygen interval points to anoxic ocean before GOE”
Anbar, Ariel; Buick, Roger; Gordon, Gwyneth; Johnson, Aleisha; Kendall, Brian; Lyons, Timothy; Ostrander, Chadlin; Planavsky, Noah; Reinhard, Christopher; Stueken, Eva (Science, 2023-04-07)Many lines of inorganic geochemical evidence suggest transient “whiffs” of environmental oxygenation before the Great Oxidation Event (GOE). Slotznick et al. assert that analyses of paleoredox proxies in the Mount McRae ... -
Trace elements at the intersection of marine biological and geochemical evolution
Robbins, Leslie J.; Lalonde, Stefan V.; Planavsky, Noah J.; Partin, Camille A.; Reinhard, Christopher T.; Kendall, Brian; Scott, Clint; Hardisty, Dalton S.; Gill, Benjamin C.; Alessi, Daniel S.; Dupont, Christoper L.; Saito, Mak A.; Crowe, Sean A.; Poulton, Simon W.; Bekker, Andrey; Lyons, Timothy W.; Konhauser, Kurt O. (Elsevier, 2016-12-01)Life requires a wide variety of bioessential trace elements to act as structural components and reactive centers in metalloenzymes. These requirements differ between organisms and have evolved over geological time, likely ...
