Constraining initial Th activity in incrementally deposited, biogenic aragonite from the Bahamas
The Th content of subsurface Bahamas seawater has been estimated from incrementally deposited aragonite skeletons of sclerosponges using U-series age models which imply syndepositional incorporation of Th. First order age models, assuming constant growth rate and zero initial Th activity, display an average surface age of 63 ± 18 y despite the fact that the surfaces of the organisms were known ...
متن کاملSulphur cycling in a Neoarchaean microbial mat
Multiple sulphur (S) isotope ratios are powerful proxies to understand the complexity of S biogeochemical cycling through Deep Time. The disappearance of a sulphur mass-independent fractionation (S-MIF) signal in rocks <~2.4 Ga has been used to date a dramatic rise in atmospheric oxygen levels. However, intricacies of the S-cycle before the Great Oxidation Event remain poorly understood. For ex...
متن کاملIsotopic fingerprints of microbial respiration in aragonite from Bahamian stromatolites
Authigenic aragonite preserves a carbon isotopic record of heterotrophic microbial influences on dissolved inorganic carbon (DIC) in microenvironments within shallow subtidal stromatolites from Highborne Cay, Bahamas. A greater amount of aragonite precipitates when and where respiration, rather than photosynthesis, influences local DIC, which is consistent with sulfate reduction promoting carbo...
متن کاملAssignment of polarization-dependent peaks in carbon K-edge spectra from biogenic and geologic aragonite.
Many biominerals, including mollusk and echinoderm shells, avian eggshells, modern and fossil bacterial sediments, planktonic coccolithophores, and foraminifera, contain carbonates in the form of biogenic aragonite or calcite. Here we analyze biogenic and geologic aragonite using different kinds of surface- and bulk-sensitive X-ray absorption near-edge structure (XANES) spectroscopy at the carb...
متن کاملRe-evaluating boron speciation in biogenic calcite and aragonite using 11B MAS NMR
Understanding the partitioning of aqueous boron species into marine carbonates is critical for constraining the boron isotope system for use as a marine pH proxy. Previous studies have assumed that boron was incorporated into carbonate through the preferential uptake of tetrahedral borate B(OH)4 . In this study we revisit this assumption through a detailed solid state B magic angle spinning (MA...
