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).

Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Early Diagenesis written by Robert A. Berner and published by Princeton University Press. This book was released on 2020-03-31 with total page 256 pages. Available in PDF, EPUB and Kindle. Book excerpt: Diagenesis refers to changes taking place in sediments after deposition. In a theoretical treatment of early diagenesis, Robert Berner shows how a rigorous development of the mathematical modeling of diagenetic processes can be useful to the understanding and interpretation of both experimental and field observations. His book is unique in that the models are based on quantitative rate expressions, in contrast to the qualitative descriptions that have dominated the field. In the opening chapters, the author develops the mathematical theory of early diagenesis, introducing a general diagenetic equation and discussing it in terms of each major diagenetic process. Included are the derivations of basic rate equations for diffusion, compaction, pore-water flow, burial advection, bioturbation, adsorption, radioactive decay, and especially chemical and biochemical reactions. Drawing on examples from the recent literature on continental-margin, pelagic, and non-marine sediments, he then illustrates the power of these diagenetic models in the study of such deposits. The book is intended not only for earth scientists studying sediments and sedimentary rocks, but also for researchers in fields such as radioactive waste disposal, petroleum and economic geology, environmental pollution, and sea-floor engineering.

This book was released on 2021-06-10 with total page 218 pages. Available in PDF, EPUB and Kindle. Book excerpt: Diagenesis of carbonates and clastic sediments encompasses the biochemical, mechanical, and chemical changes that occur in sediments subsequent to deposition and prior to low-grade metamorphism. These parameters which, to a large extent, control diagenesis in carbonates and clastic sediments include primary composition of the sediments, depositional facies, pore water chemistry, burial–thermal and tectonic evolution of the basin, and paleo-climatic conditions. Diagenetic processes involve widespread chemical, mineralogical, and isotopic modifications affected by the original mineralogy of carbonate and clastic sediments. These diagenetic alterations will impose a major control on porosity and permeability and hence on hydrocarbon reservoirs, water aquifers, and the presence of other important economic minerals. In this Special Issue, we have submissions focusing on understanding the interplay between the mineralogical and chemical changes in carbonates and clastic sediments and the diagenetic processes, fluid flow, tectonics, and mineral reactions at variable scales and environments from a verity of sedimentary basins. Quantitative analyses of diagenetic reactions in these sediments using a variety of techniques are essential for understanding the pathways of these reactions in different diagenetic environments.

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.
Download or read book Carbonate Diagenesis and Porosity written by C.H. Moore and published by Elsevier. This book was released on 1989-04-01 with total page 351 pages. Available in PDF, EPUB and Kindle. Book excerpt: Carbonate diagenesis is a subject of enormous complexity because of the basic chemical reactivity of carbonate minerals. These carbonate minerals react quickly with natural waters that either dissolve the carbonates, or precipitate new carbonates to bring the water into equilibrium with the host carbonate sediments and rocks. These rock-water interactions either create porosity by dissolution, or destroy porosity by the precipitation of carbonate cements into pore spaces. Carbonate Diagenesis and Porosity examines these important relationships in detail.This volume is published in co-operation with OGCI, and is based on training courses organised by OGCI and taught by Dr. Moore. It is intended to give the working geologist and university graduate student a reasonable overview of carbonate diagenesis and its influence on the evolution of carbonate porosity. It starts with a discussion of the major differences between carbonates and siliciclastics so that the novice will have an appreciation of the basic nature of the carbonate system. Carbonate porosity, its nature and its classification is then discussed so that the relationship between diagenesis and porosity can be established. Environments of diagenesis and their characteristics are outlined, stressing the nature of pore fluids found in each environment. Tools for the recognition of these environments are then discussed with stress on the constraints suffered by each technique. Each major diagenetic environment is then discussed in detail with petrographic, geochemical characteristics outlined, and an in depth discussion of the impact of the environment's diagenetic processes on porosity development and evolution. Diagenetic models are developed where appropriate and criteria for recognition listed. Case histories illustrating these concepts and models are presented for each major diagenetic environment and sub-environment.Over 160 line drawings illustrate the book. Petrographic characteristics of porosity and diagenetic fabrics and textures are illustrated using numerous photomicrographs taken specifically for the book by the author. The book has been extensively indexed, and includes a large, current reference section.This book should be useful to any geologist interested in, or working with, carbonate sediments and rocks. It will be particularly useful to the industrial geologist concerned with the exploration or exploitation of hydrocarbons from carbonate rock sequences where an understanding of porosity development, evolution, and prediction are important. In addition, this book will be a good text for advanced carbonate courses at graduate level, and an appropriate reference book for graduate students working in, or interested in, carbonate rock sequences and sediments.

Book excerpt: The present volume is an intellectual agglomeration covering a variety of topics in diagenesis. It starts with the diagenesis of marine pore waters and soft-sediment deformations, followed by two chapters on sandstones - one on climatic influence in terrestrial sandstone diagenesis and the other on the deep-sea volcaniclastic sandstones. Diagenesis of carbonates is treated next, with one chapter on compactional diagenesis and another devoted to a case study (Aymestry Limestone Beds, UK). There are two chapters on the origin and migration of oil: (a) maturation of organic matter, and (b) relation of diagenesis to mineralization and hydrocarbon reservoir development, followed by a chapter on sedimentary ore genesis - banded iron-formation. In conclusion there are two chapters on paleosols. This book will be of interest to geologists, geochemists and petroleum engineers.

Download or read book Quantitative Diagenesis Recent Developments and Applications to Reservoir Geology written by A. Parker and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 293 pages. Available in PDF, EPUB and Kindle. Book excerpt: Reservoirs generally consist of sandstones or carbonates exhibiting heterogeneities caused by a wide range of factors. Some of these formed depositionally (e.g. as channels, palaeosols, clay seams or salts), others may be diagenetic in origin (e.g. carbonate or silica cemented zones, authigenic clays, karstic surfaces). The severity with which diagenesis affects rock systems results from the interplay between the diagenetic process itself and the timescale over which it operated. The book provides a wide-ranging overview of diagenetic processes and responses in calcareous, argillaceous, arenaceous and carbon-rich (microbial and organic) sedimentary systems. It introduces diagenetic concepts, reviews existing knowledge, and shows how existing qualitative approaches might be developed in more quantitative ways. Several chapters consider mass balance calculations and the temporal and spatial aspects of diagenetic processes. It is unique, as a textbook, in providing such a breadth of diagenetic subject range and such depth of coverage in each topic. It provides a source reference for advanced students and professionals active in reservoir and aquifer studies.

Download or read book Geochemical Mineralogical and Microstructural Study of the Seafloor Diagenesis of Carbonate Sediments in Fort Jefferson National Monument Area written by and published by . This book was released on 1995 with total page 15 pages. Available in PDF, EPUB and Kindle. Book excerpt: The carbonate sediments from Fort Jefferson National Monument area are being studied for porewater geochemistry, mineralogy and microfabric in order to evaluate the effects of seafloor diagenesis to the sediment structure. Cementation is suggested at the depths of 120 cm and below by the increase in high-Mg/low-Mg calcite ratio determined by the Rietveld crystal structure refinement. More detailed mineralogy study and porewater geochemistry of deeper samples will possibly confirm thiS suggestion. Seafloor diagenesis may be significant at the depths where the effects of bioturbation and storm mixing do not reach. jg p.1.
Download or read book Diagenesis II written by G.V. Chilingarian and published by Elsevier. This book was released on 1988-12-01 with total page 279 pages. Available in PDF, EPUB and Kindle. Book excerpt: Diagenesis is a highly developed, interdisciplinary field of study. It is reciprocal in that it borrows from numerous scientific or technological specialities and then, in turn, repays them with useful results. Too often, however, the information gained and concepts developed remain unintegrated instead of being utilized quickly by several related earth-science fraternities. This volume, the second of a multi-volume work, attempts to bring together such information, thereby assisting the individual and the research group in keeping up with the data explosion. There is no end in sight to diagenetic research because of its wide practical and intellectual appeals. Consequently, periodic reviews, such as presented in this volume, are greatly needed.
