Book Description
The earlier editions of this book have been used by successive generations of students for more than 20 years, and it is the standard text on the subject in most British universities and many others throughout the world. The study of sediments and sedimentary rocks continues to be a core topic in the Earth Sciences and this book aims to provide a concise account of their composition, mineralogy, textures, structures, diagenesis and depositional environments. This latest edition is noteworthy for the inclusion of 16 plates with 54 colour photomicrographs of sedimentary rocks in thin-section. These bring sediments to life and show their beauty and colorful appearance down the microscope; they will aid the student enormously in laboratory petrographic work. The text has been revised where necessary and the reference and further reading lists brought up-to-date. New tables have been included to help undergraduates with rock and thin-section description and interpretation. New 16-page colour section will mean students do not need to buy Longman Atlas All illustrations redrawn to higher standard Complete revision of text - new material on sedimentary geochemistry, etc

Book Description
Carbonate rocks (limestones and dolomites) constitute a major partof the geological column and contain not only 60% of the world'sknown hydrocarbons but also host extensive mineral deposits. Thisbook represents the first major review of carbonate sedimentologysince the mid 1970's. It is aimed at the advanced undergraduate -postgraduate level and will also be of major interest to geologistsworking in the oil industry. Carbonate Sedimentology is designed to take the readerfrom the basic aspects of limestone recognition and classificationthrough to an appreciation of the most recent developments such aslarge scale facies modelling and isotope geochemistry. Novelaspects of the book include a detailed review of carbonatemineralogy, non-marine carbonate depositional environments and anin-depth look at carbonate deposition and diagenesis throughgeologic time. In addition, the reviews of individual depositionalsystems stress a process-based approach rather than one centered onsimple comparative sedimentology. The unique quality of this bookis that it contains integrated reviews of carbonate sedimentologyand diagenesis, within one volume.

Book Description
This book is an exploration of varying approaches to the study of the deposition, diagenesis and stratigraphy of evaporites. The volume includes papers from chemical modellers, who work on the basis of geochemical representations of the formative water bodies, and from basin-wide depositional-stratigraphical modellers, who propose depositional scenarios that are fitted to individual basinal pictures.Until now there have been only a few studies of evaporite formation that explain the characteristic features we observe in the real rock record. This volume is a collection of relevant papers in which these features are integrated in a realistic manner, based on our new understanding of saline water bodies, to the diverse tectonic, chemical and depositional constraints of their individual basins. In additional there are several review articles that offer oversight and extensive referencing of basins worthy of further study.This book is a valuable resource for sedimentologists and stratigraphers looking for an up-to-date reference on evaporite deposits.

Book Description
This textbook outlines the physical, chemical, and biologic properties of the major sedimentary rocks, as revealed by petrographic microscopy, geochemical techniques, and field study. It covers the mineralogy, chemistry, textures, and sedimentary structures that characterise sedimentary rocks, and relates these features to the depositional origin of the rocks and their subsequent alteration by diagenetic processes during burial. In addition to detailed sections on siliciclastic and carbonate rocks, it also discusses evaporites, cherts, iron-rich sedimentary rocks, phosphorites, and carbonaceous sedimentary rocks such as oil shales. This second edition maintains the comprehensive treatment of sedimentary petrography and petrology provided in the first edition, and has been updated with new concepts and cutting-edge techniques like cathodoluminescence imaging of sedimentary rocks and backscattered electron microscopy. It is ideal for advanced undergraduate and graduate courses in sedimentary petrology, and is a key reference for researchers and professional petroleum geoscientists.

Book Description
In recent years, interest in Neoproterozoic glaciations has grown as their pivotal role in Earth system evolution has become increasingly clear. One of the main goals of the IGCP Project number 512 was to produce a synthesis of newly available information on Neoproterozoic successions worldwide. This Memoir consists of a series of overview chapters followed by site-specific chapters. The overviews cover key topics including the history of research on Neoproterozoic glaciations, identification of glacial deposits, chemostratigraphic techniques and datasets, palaeomagnetism, biostratigraphy, geochronology and climate modelling. The site specific chapters include reviews of the history of research on these rocks and up-to-date syntheses of the structural framework, tectonic setting, palaeomagnetic & geochronological constraints, physical, biological, and chemical stratigraphy, and descriptions of the glaciogenic and associated strata, including economic deposits.

Book Description
Calcretes are an important component of many ancient fluvial, lacustrine and shallow-marine carbonate sequences, and they are widely developed in many parts of the world at the present time. Calcretes are useful to the earth scientist involved in reconstructing ancient environments, palaeoclimates and palaeographics, and they may also reveal details of soil biota and chemistry. Over the last two decades the journal Sedimentology has published a number of articles on this subject and a compilation of them is presented here. In addition to the five main sections, this volume also includes an introduction to the subject that offers a review of recent work on calcretes. The collection of papers illustrates the range of calcrete occurrences and the great variety of textures and fabrics. This volume is authored and edited by experts and will serve as more than an introduction to the subject for geologists, soil scientists and geographers.

Book Description
Over the years, many papers on carbonate diagenesis have been published in Sedimentology, the journal of the International Association of Sedimentologists. This volume presents a collection of these papers with a commentary. The emphasis of the book is on the diagenesis of shallow-marine carbonate sediments and the editors have chosen 12 papers which are reproduced in full. To widen the scope of this volume the abstracts for another 16 papers are presented. These provide further examples of diagenetic studies and help to extend the coverage of the book. The reprints and abstracts are divided into three groups, dealing with marine, meteoric and burial diagenesis respectively. Each collection is preceded by a commentary which briefly summarizes the topic and introduces the reprints and abstracts to come

Book Description
From Habitability to Life on Mars explores the current state of knowledge and questions on the past habitability of Mars and the role that rapid environmental changes may have played in the ability of prebiotic chemistry to transition to life. It investigates the role that such changes may have played in the preservation of biosignatures in the geological record and what this means for exploration strategies. Throughout the book, the authors show how the investigation of terrestrial analogs to early Martian habitats under various climates and environmental extremes provide critical clues to understand where, what and how to search for biosignatures on Mars. The authors present an introduction to the newest developments and state-of-the-art remote and in situ detection strategies and technologies that are being currently developed to support the upcoming ExoMars and Mars 2020 missions. They show how the current orbital and ground exploration is guiding the selection for future landing sites. Finally, the book concludes by discussing the critical question of the implications and ethics of finding life on Mars. - Edited by the lead on a NASA project that searches for habitability and life on Mars leading to the Mars 2020 mission - Presents the evidence, questions and answers we have today (including a summary of the current state of knowledge in advance of the ESA ExoMars and NASA Mars 2020 missions) - Includes contributions from authors directly involved in past, current and upcoming Mars missions - Provides key information as to how Mars rovers, such as ExoMars and Mars 2020, will address the search for life on Mars with their instrumentation
