Sediments, Diagenesis, and Sedimentary Rocks

Book excerpt: /inca/publications/misc/622551sample7.pdf Sample chapter Volume 7 covers the formation and biogeochemistry of a variety of important sediment types from their initial formation through their conversion (diagenesis) to sedimentary rocks. The volume deals with the chemical, mineralogical, and isotopic properties of sediments and sedimentary rocks and their use in interpreting the environment of formation and subsequent events in the history of sediments, and the nature of the ocean-atmosphere system through geological time. The volume includes information on the mineralogy and chemistry of modern marine and nonmarine sediments; geochemistry of sands, sandstones, and mudstones; interstitial waters and early diagenesis of marine sediments; the origin of the "green minerals" of glauconite, etc.; late diagenesis and mass transfer in sandstone-shale sequences; carbonate and siliceous sediment biogeochemistry and diagenesis; Precambrian chert geochemistry; organic diagenesis and biomarkers; geochemistry of coal, oil, and gas; marine phosphorite formation and diagenesis; manganese- sulfur- and iron-rich sediment geochemistry; geochemistry of marine and nonmarine evaporites; the geochemical effect of impact events; chronometry of sediments and sedimentary rocks; and the evolution of the ocean-atmosphere system as deduced from biogeochemical and isotopic features in sedimentary rocks.
