Available in PDF, EPUB and Kindle. Book excerpt: Biology and Evolution of the Mexican Cavefish features contributions by leading researchers in a comprehensive, unique work that examines a number of distinct areas of biology—evolution, development, ecology, and behavior—using the Mexican cavefish as a powerful model system to further understanding of basic biological processes such as eye degeneration, hearing, craniofacial development, sleep, and metabolic function. These fish are currently being used to better understand a number of issues related to human health, including age-related blindness, sleep, obesity, mood-related disorders, and aging. The recent sequencing of the cavefish genome broadens the interest of this system to groups working with diverse biological systems, and has helped researchers identify genes that regulate sleep, eye degeneration, and metabolic function. Mexican cavefish are particularly powerful for the study of biological processes because these fish evolved independently in twenty-nine caves in the Sierra de el Abra Region of Northeast Mexico. These fish have dramatic adaptations to the cave environment, and this can be used to identify genes involved in disease-related traits. This scholarly text will be of interest to researchers and students throughout diverse areas of biology and ecology. It includes photographs of animals and behavior in laboratory and natural settings that will also increase interest and accessibility to non-experts. Includes a mixture of images and illustrations such as the geographical distribution of cave pools and the developmental biology of the nervous system Features a companion site with geographical maps Fills a notable gap in the literature on a topic of broad interest to the scientific community Presents the recent sequencing of the cavefish genome as a groundbreaking development for researchers working with diverse biological systems

Download or read book Carbonate Reservoirs written by Clyde H. Moore and published by Elsevier Inc. Chapters. This book was released on 2013-08-12 with total page 392 pages. Available in PDF, EPUB and Kindle. Book excerpt: Major porosity-modifying processes operating in the marine diagenetic realm are (1) cementation in shallow warm waters, (2) dolomitization accompanied by minor porosity enhancement in deep waters below the aragonite and calcite lysoclines, and (3) dolomitization associated with organic degradation during early burial. In shallow, normal marine environments, porosity is lost through abiotic and microbially mediated cementation. Such cementation is most abundant in shelf-margin reefs, high-energy intertidal zones, and isolated hardgrounds. Abiotic and microbial cementation in reefs—in combination with bioerosion and internal sedimentation—can totally destroy high initial reef framework porosities. Although intertidal and hardground cements tend to be vertically and laterally restricted, these zones can act as permeability barriers in reservoirs. Deep marine slope and basin environments can experience significant porosity modification. Aragonite cementation on the upper slope extends to 60m depth at present. During the Paleozoic and Mesozoic eras, carbonate mud mounds developed on upper shelf slopes and distal ramps. Microbial processes in these mounds contributed to both early cementation and dissolution. Many such mounds formed in conjunction with hydrothermal and cold petroleum vents on the seafloor; some of these mud mounds are significant reservoirs. Where the thermocline and carbonate lysoclines impinge on steep carbonate platform margins that front oceanic basins, dissolution of aragonite and/or calcite, precipitation of radiaxial calcite cement, and dolomitization can occur. Kohout thermal convection and mixing-zone-induced seawater circulation are the most likely hydrologic pumps driving large volumes of marine water through steep platform margins. At relatively shallow depths in the sediment/rock column, decomposition of organic matter mediated by sulfate-reducing bacteria can promote dissolution of aragonite and Mg-calcite, calcite cementation, and massive dolomitization.
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 337 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.

Available in PDF, EPUB and Kindle. Book excerpt: Since 1950 geologists have learned more about the origin and lithification of carbonate sediments than in all the previous years of the history of science. This is true in all the diverse fields of carbonate geology: the study of Recent environments, marine zoology and botany, organic geochemistry, trace element and isotope geochemistry, mineralogy, microfacies of depositional environments, and trace-fossil and sedimentary structure investigation. A synthesis of this new knowledge is just beginning to be formulated. The purpose of this volume is to introduce the advanced student and petroleum explorationist principally to one important aspect of this study: to some of the principles of carbonate geology which may serve to interpret the depositional environments of ancient strata and to better define their sequences and patterns. Chapter I is a brief review of principles of carbonate sedimentation. (For a full discussion of the mineralogy, geochemistry, and diagenesis of carbonates along with a review of Holocene sediments, one may refer to Bathurst's (1971) and Milliman's (1974) texts.) Chapter II reviews stratigraphic and paleotectonic concepts and discusses a general model for carbonate deposition. Chapter III offers an outline of carbonate petrography, concentrating on lithologic descrip tion for the purposes of environmental interpretation. For a further review of this subject and excellent photomicrographs, Horowitz and Potter (1971) and Majewske (1969) may be used.
