More than half of the world’s petroleum is found in carbonate rocks — for example, in the Middle East, the former USSR and in North America. These rocks show a bewildering diversity of grains and textures, due in part to the wealth of different fossil organisms that have contributed to carbonate sedimentation, and in part to a wide variety of diagenetic processes that can radically modify textures and obscure the depositional fabric. Careful petrographic study with a polarising microscope is a key element of any study of carbonate sediments — as a companion to field or core logging and as a necessary precursor to geochemical analysis. This atlas, which illustrates in full color a range of features not attempted in any general textbook, is designed as a laboratory manual to keep beside the microscope, and as an aid to identifying grain types and textures in carbonates. It will appeal alike to under-graduate and graduate students and to professionals in teaching institutions, research laboratories and industry.

Backscattered scanning electron microscopy (BSE) reveals the minerals, textures, and fabrics of sediments and rocks in much greater detail than is possible with conventional optical microscopy. Backscattered Scanning Electron Microscopy provides a concise summary of the BSE technique. This comprehensive guide uses abundant images to illustrate the type of information BSE yields and the application of the technique to the study of sediments and sedimentary rocks. The authors review the use of this petrographic technique on all the major sedimentary rock types, including sediment grains, sandstones, shales, carbonate rocks, rock varnish, and glauconite. They also describe image analysis techniques that allow quantification of backscattered scanning electron microscope images. Heavily illustrated and lucidly written, this book will provide researchers and graduate students with the most current research on this important geological tool.
Advanced textbook outlining the physical, chemical, and biological properties of sedimentary rocks through petrographic microscopy, geochemical techniques, and field study.
This is the book you need to improve your interpretations of carbonates. Using a systematic treatment of the entire subject of carbonate depositional environments, this unique book is specifically designed for use by the non-specialist -- the petroleum geologist or field geologist -- who uses carbonate depositional environments in facies reconstructions and environmental intepretations. This classic work, covering settings from non-marine to deep water, focuses on the recognition of depositional environments with extenive use of color diagrams and photographs of sedimentary structures and facies assemblages. Although the ultimate purpose of this text is to improve exploration for oil, gas, and mineral deposits, it also includes environments not normally considered to be particularly prospective for oil and gas in an attempt to provide as complete a framework as possible for recognition of environments. Suitable for use as a textbook, this book is also an invaluable reference fo the specialist or advanced graduate student. It provides perspective on large-scale influences on carbonate depositional envionments such as tectonic patterns, fluctuations of sea level, variations of climate, and evolutionary patterns of organisms. --
The earlier editions of this book have been used by successivegenerations of students for more than 20 years, and it is thestandard text on the subject in most British universities and manyothers throughout the world. The study of sediments and sedimentary rocks continues to be acore topic in the Earth Sciences and this book aims to provide aconcise account of their composition, mineralogy, textures,structures, diagenesis and depositional environments. This latest edition is noteworthy for the inclusion of 16 plateswith 54 colour photomicrographs of sedimentary rocks inthin-section. These bring sediments to life and show their beautyand colorful appearance down the microscope; they will aid thestudent enormously in laboratory petrographic work. The text hasbeen revised where necessary and the reference and further readinglists brought up-to-date. New tables have been included to helpundergraduates with rock and thin-section description andinterpretation. New 16-page colour section will mean students do not need tobuy Longman Atlas All illustrations redrawn to higher standard Complete revision of text - new material on sedimentarygeochemistry, etc
A companion volume to the "Atlas of rock-forming minerals in thin section", this full-colour handbook is designed to be used as a laboratory manual both by elementary students of earth sciences undertaking a study of igneous rocks in thin section under the microscope, and by more advanced students and teachers as a reference work. The book is divided into two parts - Part one is devoted to photographs of many of the common textures found in igneous rocks with brief descriptions accompanying each photograph. Part two illustrates the appearance of examples of some sixty of the commonest (and a few not so common) igneous rock types; each photograph is accompanied by a brief description of the field of view shown. Nearly 300 full-colour photographs are included, and in many cases the same view is shown both in plen-polarized light and under crossed polars. A brief account of how thin sections can be prepared is included as an appendix.
