Sand and Sandstone


Book Description

The first edition appeared fourteen years ago. Since then there have been significant advances in our science that warrant an updating and revision of Sand and Sandstone. The main framework of the first edition has been retained so that the reader can begin with the mineralogy and textural properties of sands and sandstones, progress through their organization and classification and their study as a body of rock, to consideration of their origin-prove nance, transportation, deposition, and lithification-and finally to their place in the stratigraphic column and the basin. The last decade has seen the rise of facies analysis based on a closer look at the stratigraphic record and the recognition of characteristic bed ding sequences that are the signatures of some geologic process-such as a prograding shallow-water delta or the migration of a point bar on an alluvial floodplain. The environment of sand deposition is more closely determined by its place in such depositional systems than by criteria based on textural characteristics-the "fingerprint" approach. Our revi sion reflects this change in thinking. As in the geological sciences as a whole, the concept of plate tectonics has required a rethinking of our older ideas about the origin and accumu lation of sediments-especially the nature of the sedimentary basins.

Lithostratigraphic Analysis of Sedimentary Basins


Book Description

Lithostratigraphic Analysis of Sedimentary Basins deals with the concepts and methodology of lithostratigraphic analysis used to elucidate various aspects of the geological history of sedimentary layers within a basin. The principles of stratigraphy and sedimentation as well as the influence of tectonism are discussed, along with their relevance to a variety of methods employed in the analysis of sedimentary basins. Comprised of seven chapters, this book begins with a classification of sedimentary basins and an overview of the methods used in their analysis. Certain lithological features, including sedimentary structures, textures, and assemblages of features that are considered to be diagnostic or indicative of particular depositional environments, are discussed, together with their implications for interpretations of the geologic history of a sedimentary basin on the basis of both macrostratigraphic and microstratigraphic criteria. Other lithologic analyses that are mentioned relate to petrophysical properties such as porosity and permeability and to chemical properties such as trace element, organic, and hydrocarbon content. Methods employed in the examination of outcrops and rock samples are also considered. The final chapter describes the application of sedimentary basin analysis to exploration of oil and gas, coal, and minerals, together with potential storage reservoirs for natural gas. This monograph will be of interest to geophysicists, geologists, geophysicists, and engineers.




Lacustrine Sandstone Reservoirs and Hydrocarbon Systems


Book Description

Many publications on lacustrine systems concentrate on reconstructing paleo-environments, deciphering paleoclimate or estimating hydrocarbon source potential. This is the first memoir to give attention to describing the occurrence, distribution and character of sandstones in various lake settings. The memoir is divided into four sections beginning with a global overview, and followed by two sections covering lacustrine systems in compressional and extensional regimes, and concludes with a series of papers on modern lake regimes.




Sandstone Depositional Models for Exploration for Fossil Fuels


Book Description

The purpose of this monograph is to provide participants in my various short courses with a brief statement of the material I cover in my lectures. In addition, key illustrations are reproduced for guidance. A brief bibliography of reference material is appended to each chapter. The bibliographic material includes those references that I consider critical to my remarks. No claim is made of topical or bibliographic completeness. This monograph also is intended as a brief summary of depositional processes, Holocene sediments, ancient counterparts of depositional environments, and examples of oil- and gas-bearing stratigraphic traps in five depositional environments. This summary is intended to complement lecture and reading courses dealing with sedimentology, depositional systems, sedimentary facies, sedimentary environments, sandstone diagenesis, and sedimentary modelling as a predictive tool for exploration. The student is cautioned, however, that this monograph is merely an introduction and summary overview of the subject. More complete treatments appear in standard textbooks. Sedimentology has changed and advanced over the past twenty-five years, in part because the American oil industry needed to make predictions about the occurrence of the harder-to-find stratigraphic traps. In addition, the development of plate-tectonic theory, and supportive data from the Deep Sea Drilling Project, have caused sedimentology to change from an essentially descriptive science to a mature, predictive science. The 1960s and 1970s in particular witnessed an explosion of new insights and understanding of how sediments are deposited, and how sedimentary rocks are formed.




Deltaic Sand Bodies


Book Description
