Understanding the origin and evolution of life on Earth potentially other planets in our solar system is fundamental interest for humanity. For longest time Earth's history, evolved microbial communities. It is, however, still incompletely understood how, when where such habitable environments formed how communities adopted to drastic changes atmosphere-hydrosphere-lithosphere systems through deep time. Stromatolites, i.e., lithified mats that occur sedimentary successions from at least 3.4...
Tungsten is a highly incompatible and fluid mobile element in the Earth's crust mantle, but its geochemical cycle magmatic systems still remains poorly understood. stable isotopes represent novel tool with potential to better constrain this cycle, because of possible W isotope fractionation during changes redox-state (valence states +4 +6) coordination (tetrahedral octahedral). By employing 180W-183W double spike our analytical protocol for measurements yields an external reproducibility...
Abstract There are current debates around the extent of global ocean oxygenation, particularly from late Neoproterozoic to early Paleozoic, based on analyses various geochemical indices. We present a temporal trend in excess barium (Baexcess) contents marine organic-rich mudrocks (ORMs) provide an independent constraint redox evolution. The absence remarkable Baexcess enrichments Precambrian (>ca. 541 Ma) ORMs suggests limited authigenic Ba formation oxygen- and sulfate-deficient...
Cap dolostones of the Ediacaran Doushantuo Formation (Yangtze Platform, South China) from various palaeo-water depths were studied to evaluate extent their diagenetic alteration and assess temporal spatial variations seawater chemistry in aftermath Marinoan glaciation. Diagenetic fluid overprint is common cap dolostone lithologies. However, mobilization trace elements modification Sr O isotopic compositions are variable controlled by multiple stages overprint. The highest 87 Sr/ 86 ratios...
The behaviour of bioavailable trace metals and their stable isotopes in the modern oceans is controlled by uptake into phototrophic organisms adsorption on incorporation marine authigenic minerals. Among other bioessential metals, Cd its have recently been used carbonate lithologies as novel tracer for changes paleo primary productivity (bio)geochemical cycling. However, many sediments that were deposited during geologically highly relevant episodes which, thus, urgently require study a...
Abstract The South Yellow Sea is an important sink for sediments delivered by the and Yangtze rivers in East Asia. We conducted a high‐resolution geochemical analysis on bulk retrieved from marine drill core (CSDP‐1) using method of X‐ray fluorescence (XRF). Our results show large variations along core. As demonstrated linear correlations with Al‐Si link compositional principal component (PCA), elemental ratios among Al, K, Zr, Ba, Si are primarily controlled sediment sorting effects. A...
