Available in PDF, EPUB and Kindle. Book excerpt: "Modern and ancient sediments are complex biogeochemical systems where multiple sulphur isotopes may be useful in tracing previously unseen processes. Multiple sulphur isotope signatures of pore water sulphate from methane-rich marine sediments indicate different microbial pathways involved in the overall sulphur cycling. Particularly in chapter 2, we found that sulphate reduction is the only microbial process controlling the sulphur cycling at station 12 but at station 5 up to 60% of sulphide produced from sulphate reduction re-oxidizes back to sulphate. We are only able to tell this difference with multiple sulphur isotopes. (Chapter 2- Hidden sulphur cycle stimulates the microbial methane biofilter in deep marine sediments)Beside biological processes, transport of material may cause isotope fractionation. We analyze multiple sulphur isotope composition of dissolved sulphate and sulphide when these ions diffused through an acrylamide gel column. The experimental results showed that the diffusion-associated isotope fractionation of ion sulphate is insignificant within the study size (~20 cm length) but the diffusion-associated isotope fractionation of ion sulphide is clearly observable (34[alpha] = 0.9990±0.0005). With that fractionation factor, when sulphide diffuses 1 meter away from the source, it is at least 10[per mil] lighter than the original isotope composition. (Chapter 3 - Sulphur isotope effects of [("SO")]_4^(2-) and [("HS")]_^- diffusion in water). In chapter 4, we apply multiple sulphur isotope techniques to study the sulphur cycling during the end-Permian mass extinction. Minor sulphur isotope signature suggests the mixing of at least two distinct sulphur sources during that time period. We have proposed possible sulphur sources even though further studies are required in order to identify exactly which sources contributed to the sulphur enrichment at Permian-Triassic period (Chapter 4 - Sulphur and carbon isotope records across the terrestrial Permian-Triassic (P-T) boundary)." --

Download or read book Evaluation of Early Diagenesis in Modern Shallow Water Carbonate Sediments by Mineralogy Fabric and Porewater Geochemistry written by and published by . This book was released on 1995 with total page 10 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mineralogy, fabric and porewater geochemistry were examined in order to study early diagenesis in modern, shallow-water carbonate sediments of Key West area. The evidence for early diagenesis is visible as micritic cement in SEM images of sediment samples. Because the major cation concentrations are found to be insensitive to the diagenetic reactions in the study area, mineralogy instead of porewater geochemistry will be used to quantify the extent of early diagenesis. Rietveld crystal structure refinement method will be used for the accurate quantification of phase transformations. (MM).

Download or read book Compaction and Earliest Pore water Diagenesis in Late Pleistocene Holocene Pelagic and Terrigenous Sediments of the Labrador Sea written by Mark Edmund Fay and published by . This book was released on 1994 with total page 392 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Two deep-sea cores from the Labrador Sea have been examined using a variety of techniques. Sediments from the eastern levee of the North Atlantic Mid-Ocean Channel consist of spill-over turbidites interstratified with hemipelagic sediments and ice-rafted detritus which are correlatable with levee cores described in earlier studies. The same facies are found on the lower Labrador Slope except that, here, the amount of ice-rafted detritus in the hemipelagic facies is more variable. Compressibility tests have enabled an evaluation of the porosity-permeability character of the levee spill-over facies at deeper levels of burial. Organic- and inorganic carbon contents, shear strength and porosity are unique to each facies. These, and the chemistry of the pore waters have been used to infer the early diagenetic processes occurring at both sites." --
