This volume 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. Reprinted individual volume from the acclaimed Treatise on Geochemistry, (10 Volume Set, ISBN 0-08-043751-6, published in 2003). - Comprehensive and authoritative scope and focus - Reviews from renowned scientists across a range of subjects, providing both overviews and new data, supplemented by extensive bibliographies - Extensive illustrations and examples from the field

/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.

Diagenesis in sediments and sedimentary rocks

The topic of sediment diagenesis is of fundamental importance to industry in the evaluation of hydrocarbon and water reservoir rocks. Detailed knowledge of the diagenetic textures, fabrics, and minerals, and a prediction of the regional diagenetic response, partly controls hydrocarbon recovery programmes. In other words, knowledge of the diagenesis can aid (or even control) conservation policy. Similarly, facies and diagenetic trends w.ithin basins can influence exploration policy. This volume incorporates the majority of the principal contributions given to the NATO Advanced Study Institute held in the University of Reading, U.K., from July 12th-25th, 1981, at which the major themes of carbonate and terrigenous clastic sediments were treated sequentially from deposition to deep burial. Eighty selected scientists from twelve NATO and three other countries participated in the Institute. The keynote addresses which acted as the touchstones for discussion are presented here in the expectation that they will stimulate a still wider audience. We gratefully acknowledge the award of a grant from the Scientific Affairs Division of NATO to run the Institute, and also the cooperation of the University of Reading. Mrs. D. M. Powell helped in many ways with the organisation, and also retyped the entire manuscript of this book. A. Parker B. lv.
