The basis of this investigation is the petrographic and geochemical understanding of principal igneous rock types of the Noril’sk region, in order to demonstrate that these data provide unique and self-evident solutions to the problems of petrogenesis and mineralization. The results of the investigations are presented in two volumes: the first includes mainly text and the second contains illustrations. In the first volume, the state of the main problems of the genesis of igneous rocks with reference to Traps and related ore deposits is discussed, as well as short petrological descriptions of igneous complexes in the region, the mineral and geochemical diversity of the rocks, and aspects of the differentiation of basaltic melts and mineralization are described. Taking into account the vast number of publications on the petrology of Traps of the Noril’sk region, primary attention in the monograph is given to earlier unknown phenomena, as well as other aspects that are of great importance for solving genetic problems. Some exotic geologic targets such as the Mikchandinsky differentiated cover, the magnetite lava flow of the Putorana Plateau, the magmatogenic breccia of Kharaelakh and others are described in detail. The second volume contains an atlas of Rock Indications of igneous rock-types; formally identified reference rocks from all igneous complexes of the region, as well as photographs of thin sections of typical rocks and analytical tables of rocks and minerals from the key sections of sedimentary units and intrusions. Each rock type has been geochemically and petrographically analysed thereby providing a formal identity, complete with a photograph of the thin section. Photomicrographs of the rocks in this book will be a useful aid in visualizing the diversity of rock types in the Traps; each photograph reflecting a unique combination of minerals.

This book by Vietnamese and Russian authors is the first of its kind and combines the extensive knowledge on the petrology and metallogeny of the late Paleozoic - early Mesozoic and Cenozoic periods in North Vietnam. The Permian - Triassic and Paleogene volcano-plutonic and plutonic associations are two important geological events in the evolutionary history of Southeast Asia, including the 260 - 250 Ma Emeishan mantle plume and Indian-Eurasia collision at 60 - 55 M. The volume includes 9 chapters, divided into 3 parts. Part 1 introduces the geological structure of North Vietnam; Part 2 covers the Permian - Triassic magma associations and metallogeny; and Part 3 focuses on the Cenozoic magma associations and metallogeny. In each chapter, the geological setting of magmas, classification of different geological structures, and composition characteristics, such as mineralogy, geochemistry, isotope systematics and geochronology are discussed. This book represents an important reference document for international and Vietnamese geologists engaged in the geological history and metallogeny of Vietnam, an important area of the Asian continent. The monograph also has a practical significance in contributing new premises and to assess rare and precious mineral prospects. In addition, it can be regarded as a necessary data base for petrological and metallogenic projects and university courses.

The aim of this book is to unlock the power of the freeware R language to advanced university students and researchers dealing with whole-rock geochemistry of (meta-) igneous rocks. The first part covers data input/output, calculation of commonly used indexes and plotting in R. The core of the book then focusses on the presentation and practical implementations of modelling techniques used for fingerprinting processes such as partial melting, fractional crystallization, binary mixing or AFC using major-, trace-element and radiogenic isotope data. The reader will be given a firm theoretical basis for forward/reverse modelling, followed by exercises dealing with typical problems likely to be encountered in real life, and their solutions using R. The concluding sections demonstrate, using practical examples, how a researcher can proceed in developing a realistic model simulating natural systems. The appendices outline the fundamentals of the R language and provide a quick introduction to the open-source R-package GCDkit for interpretation of whole-rock geochemical data from igneous and metamorphic rocks.

This book reviews the geochemical and petrological characteristics of potassic igneous rock complexes, and investigates the different tectonic settings in which these rocks occur. The authors provide an overview and classification of these rocks and elucidate the geochemical differences between barren and mineralized potassic igneous complexes. High-K rocks host a number of epithermal gold and porphyry copper-gold deposits. In recent years, there has also been growing recognition of an association of such rocks with iron-oxide copper-gold (IOCG) deposits, intrusion-related gold deposits (IRGDs) and possibly even Carlin-type gold deposits. This book is not only relevant to academic petrologists working on alkaline rocks, but also to exploration geologists prospecting for epithermal gold and/or porphyry copper-gold deposits in modern and ancient terrains. This fourth, updated and expanded edition incorporates new data and references from Africa, Australia, Brazil, China, Greece, Iran, Mongolia, North America, Russia and Turkey, including new maps and sections and new color plates of high-grade gold-copper ore from major deposits hosted by potassic igneous rocks.

Thermochronology, the study of the thermal history of rocks, enables us to quantify the nature and timing of tectonic processes. First published in 2006, Quantitative Thermochronology is a robust review of isotopic ages, and presents a range of numerical modeling techniques to allow the physical implications of isotopic age data to be explored. The authors provide analytical, semi-analytical and numerical solutions to the heat transfer equation in a range of tectonic settings and under varying boundary conditions. They then illustrate their modeling approach built around a large number of case studies. The benefits of different thermochronological techniques are also described. Computer programs on an accompanying website at www.cambridge.org/9781107407152 are introduced through the text and provide a means of solving the heat transport equation in the deforming Earth to predict the ages of rocks and compare them directly to geological and geochronological data. Several short tutorials, with hints and solutions, are also included.

The book offers a modern, comprehensive, and holistic view of natural gas seepage, defined as the visible or invisible flow of gaseous hydrocarbons from subsurface sources to Earth's surface. Beginning with definitions, classifications for onshore and offshore seepage, and fundamentals on gas migration mechanisms, the book reports the latest findings for the global distribution of gas seepage and describes detection methods. Seepage implications are discussed in relation to petroleum exploration, environmental impacts (hazards, pollution, atmospheric emissions, and past climate change), emerging scientific issues (abiotic gas and methane on Mars), and the role of seeps in ancient cultures. With an updated bibliography and an integrated analysis of available data, the book offers a new fundamental awareness - gas seepage is more widespread than previously thought and influences all of Earth's external "spheres", including the hydrosphere, atmosphere, biosphere, and anthroposphere.

Igneous and metamorphic petrology has over the last twenty years expanded rapidly into a broad, multifaceted and increasingly quantitative science. Advances in geochemistry, geochronology, and geophysics, as well as the appearance of new analytical tools, have all contributed to new ways of thinking about the origin and evolution of magmas, and the processes driving metamorphism.

This book is designed to give students a balanced and comprehensive coverage of these new advances, as well as a firm grounding in the classical aspects of igneous and metamorphic petrology. The emphasis throughout is on the processes controlling petrogenesis, but care is taken to present the important descriptive information so crucial to interpretation.
One of the most up-to-date synthesis of igneous and metamorphic petrology available.
Emphasis throughout on latest experimental and field data.
Igneous and metamorphic sections can be used independently if necessary.

The book summarizes the occurrence, geochemistry, mineralogy, petrology and phase-equilibria studies in air and under high pressures related to the most intriguing group of potassium-rich mafic and ultramafic rocks, often including host of exotic mineral assemblages including feldspathoids. Mantle-derived K-rich melts had intrigued most of the founders of Geology and many of the later experts in the field of Igneous Petrology, because they are sometimes associated with carbonatites and even diamond. They tend to contain anomalous concentration of many such elements as K, Rb, Sr, U, F, P, etc., along with Ni, Co and Cr indicating a mixture of crust and mantle materials. Although these rocks occur rarely in ancient geologic time, they have been erupting mostly in modern geological history (less than last 120 Ma or so). Are the old age data real or the result of a sampling problem? Modern observations leave no doubt that sediments must be subducted on a large scale. There is now evidence that the upper mantle (and perhaps even the lower mantle) is not homogeneous but rather like a fruit cake, and that there are thermal anomalies in the mantle resulting from deep mantle plumes or subduction. Is this related to release of these unusual rocks clearing the mantle of left over subduction materials? This volume, written for those interested in the geochemistry of K-rich melts from the deep Earth, reviews the present state of knowledge of these unique igneous rocks. The author is an expert in the field of Igneous Petrology and the book will serve as a valuable reference book for researchers and academicians in the discipline.

Originally published during the early part of the twentieth century, the Cambridge Manuals of Science and Literature were designed to provide concise introductions to a broad range of topics. They were written by experts for the general reader and combined a comprehensive approach to knowledge with an emphasis on accessibility. This volume contains the 1922 second edition of Grenville A. J. Cole's Rocks and their Origins, first published in 1912. Intended for non-specialists, the book offers six concise chapters on various rock types, their characteristics, and their formation.

This book was first published in 1973. Its authors, David Krinsley and John Doornkamp, have here compiled a comprehensive catalogue of the many presences and absences found within the characteristics of different types of quartz grain sand. Their study was originally designed to fill those gaps which existed in the field of quartz grain surface texture research at the time. The focal point of Krinsley and Doornkamp's work is found in its numerous micrographs, selected specifically for their ability to demonstrate the many variations in the surface textures of quartz grain sand. Although much progress has been made in this field since the book's publication, it will still be of great interest to all researchers with an interest in this topic. The four-page bibliography provided by the authors also makes this book a useful reference point for all scholars wishing to explore the history and development of this fascinating discipline.

Much of the world's petroleum is located on continental margins, and any further development of these offshore deposits would be impossible without new technologies and new methods contained in this volume. Written by some of the world's foremost authorities on oil and gas, this volume explains for the practicing engineer and the engineering student some of the most important and cutting-edge techniques for developing offshore fields on continental margins.

Alfred Harker (1859 1939) was a prominent petrologist who spent his career at St John's College, Cambridge, lecturing on and researching rock formations and related geological activity. He was elected a fellow of the Royal Society in 1902, and was president of the Geological Society from 1916 to 1918. He used his Cambridge lectures as the foundation for this book (first published in 1909), offering an introduction to the development of rocks and related volcanic activity. With more than one hundred diagrams of various aspects of geological formations, this work also provides a visual guide to the location and formation of igneous rocks. Over the course of the work, he covers the themes of vulcanicity, rock structure, crystallization, the role of magma and the principles of rock classification, giving a broad picture of the field of petrology around the beginning of the twentieth century.

The papers within these volumes were compiled between late 1978 and early 1980, from data on tillites and tillite-like rocks. The research was conducted for the Pre-Pleistocene Tillite Project of the International Geological Correlation Programme, and was first published in volume form in 1981. In this substantial work, M. J. Hambrey and W. B. Harland have assembled essays by leaders in the field of pre-Pleistocene glacial research. The work's various chapters review in depth the glacial records of Africa, Antarctica, Asia, Australasia, Europe, and North and South America. The second volume concludes with a fascinating editorial overview of the pre-Pleistocene glacial record of the Earth as a whole. The reader is also presented with a collection of readily accessible statistics, maps and charts. This set will be of particular use to scholars of sedimentology, paleoclimatic patterns, climate change and ice ages, and the time-correlation of rocks.

Following their recognition by GUmbel (1874), lamprophyres were treated for an entire century as little more than obscure curiosities. Although this situation has changed recently, with a flowering of publications and active workers, lamprophyres remain almost the only group of igneous rocks which have not yet received attention in a dedicated monograph. In five exploratory reviews (1977-1987), the writer aimed to set out what was known about these rocks. The lUGS Subcommission on igneous rock systematics had meanwhile presented its nomenclatural framework (Streckeisen 1979). All this has now been overtaken by a recent explosion of interest, epitomized not least by lamprophyres' greater prominence in the 4th International Kimberlite Conference Proceedings. More data have become available since 1985 than over the entire previous century, and it is obviously impossible for such an extraordinary outpouring to be fully reviewed in this first, preliminary book. At the risk of dissatisfying some readers, therefore, this book concentrates on factual matters, and on a broad overview rather than minutiae. Because not even a world map of known lamprophyres was previously available, almost half the book is deliberately taken up by the first global lamprophyre compilation, and its commensurately extensive Bibliography. Such a compendium of largely objective information is believed to be of more immediate interest and lasting value than a premature pottage of petrogenetic polemic. Chapters 1-7 bring previous studies up to date, and concentrate on factual information.

Igneous petrology was to some extent essentially a descriptive sci ence until about 1960. The results were mainly obtained from field work, major element analyses, and microscopical studies. During the 1960's two simultaneous developments took place, plate tectonics became generally accepted, and the generation of magmas could now be related to the geodynamic features like convection cells and subduction zones. The other new feature was the development of new analytical apparatus which allowed high accuracy analyses of trace elements and isotopes. In addition it became possible to do ex perimental studies at pressures up to 100 kbar. During the 1970's a large amount of analytical data was obtained and it became evident that the igneous processes that control the compositions of magmas are not that simple to determine. The composition of a magma is controlled by the compositions of its source, the degree of partial melting, and the degree of fractionation. In order to understand the significance of these various processes the relationship between the physical processes and their geochemical consequences should be known. Presently there are several theories that attempt to explain the origin of the various magma types, and these theories can only be evaluated by turning the different ideas into quantitative models. We will so to speak have to do some book keeping for the various theories in order to see which ones are valid. the present book is intended as an introduction to the more fun damental aspects of quantitative igneous petrology."

The first edition of this book was published in 1965 and its French translation in 1966. The revised second edition followed in 1967 and its Russian translation became available in 1969. Since then, many new petrographic observations and experimental data elucidat- ing reactions in metamorphic rocks have made a new approach in the study of metamorphic transformation desirable and possible. It is felt that this new approach, attempted in this book, leads to a better unders- tanding of rock metamorphism. The concept of metamorphic facies and subfacies considers asso- ciations of mineral assemblages from diverse bulk compositions as characteristic of a certain pressure-temperature range. As new petrographic observations accumulated, it became increasingly difficult to accommodate this information within a manageable framework of metamorphic facies and subfacies. Instead, it turned out that mineral assemblages due to reactions in common rocks of a particular composi- tion provide suitable indicators of metamorphic conditions. Metamorphic zones, defined on the basis of mineral reactions, very effectively display the evolution of metamorphic rocks. Thus the im- portance of reactions in metamorphic rocks is emphasized. Experimen- tal calibration of mineral reactions makes it possible to distinguish reac- tions which are of petrogenetic significance from those which are not. This distinction provides guidance in petrographic investigations un- dertaken with the object of deducing the physical conditions of metamorphism.

Comprising a guidebook and a full color CD-ROM, this reference set offers illustrated essentials to study mineralogy, applied to petrology. While there are some excellent reference works available on this subject, this work is unique for its data richness and its visual character.

With a collection of images that excels both in detail and aesthetics, 151 minerals are presented in more than 400 plates. Different facies and paragenesis, both in natural polarized light, are shown for every mineral and optical data, sketches of the crystal habitus, chemical composition, occurrence and a brief description are included. The accompanying user guide gives a general introduction to microscope mineral observation, systematic mineralogy, mineral chemistry, occurrence, stability, paragenesis, structural formula calculation and its use in petrology.

This compact set will serve as a field manual to students, researchers and professionals in geology, geological, mining, and mineral resources engineering to observe and determine minerals in their studies or field work.

Granite petrology has achieved significant progress since Tuttle and Bowen (1958) wrote the monograph on the Origin of granite in the light of experimental studies in the system NaAISi308-KAISi308-SiOrH20. Since then, the compo nents CaAI Si 0, FeO, MgO, and excess alumina have 2 2 s been added to the pure system Ab-Or-Qz-H 0 in order to 2 include plagioclase and common mafic minerals in the inves tigations. In addition to synthetic systems, natural rocks have been used as starting materials, and other fluid compo or substituted for water. nents have been added to There are many new data concerning properties of melts and magmas, dehydration melting of synthetic and natural rocks, and phase relationships at H 0-undersaturated con 2 ditions. We found it useful and necessary to summarize the available information in this volume, and an effort has been made to present up-to-date data on various aspects of gran ite petrology. Most parts of the manuscript were reviewed by John Clemens, Peter Nabelek, and Alan White. Their friendly help and suggestions improved it considerably. Some chap ters of this volume benefited from critical review by William Brown, Bruno Scaillet, and Robert Linnen. Peter Wyllie pro vided us with reprints and many critical and useful sugges tions. Jagmohan Singh improved the English considerably."

In recent years, there has been increasing interest from geoscientists in potassic ig- neous rocks. Academic geoscientists have been interested in their petrogenesis and their potential value in defining the tectonic setting of the terranes into which they were intruded, and exploration geoscientists have become increasingly interested in the association of these rocks with major epithermal gold and porphyry gold-copper deposits. Despite this current interest, there is no comprehensive textbook that deals with these aspects of potassic igneous rocks. This book redresses this situation by elucidating the characteristic features of po- tassic (high-K) igneous rocks, erecting a hierarchical scheme that alIows interpreta- tion of their tectonic setting using whole-rock geochemistry, and investigating their associations with a variety of gold and copper-gold deposits, worldwide. About half of the book is based on a PhD thesis by Dr Daniel MillIer which was produced at the Centre for Strategic Mineral Deposits (former ARC Key Centre) within the Depart- ment of Geology and Geophysics at The University of Western Australia under the supervision of Professor David Groves, the late Dr Nick Rock, Professor Eugen Stumpf}, Dr Wayne Taylor, and Dr Brendan Griffin. The remainder of the book was compiled from the literature using the collective experience of the two authors. The book is dedicated to the memory of Dr Rock who initiated the research project but died before its completion.

Minerals in sedimentary rocks emit characteristic visible luminescence called cathodoluminescence (CL) when bombarded by high energy electrons. CL emissions can be displayed as colour images in a cathodoluminescence microscope or as high-resolution monochromatic images in a scanning electron microscope. This provides information not available by other techniques on the provenance of the mineral grains in sedimentary rocks, and insights into diagenetic changes. The book, first published in 2006, begins with an easily understood presentation of the fundamental principles of CL imaging. This is followed by a description and discussion of the instruments used in CL imaging, and a detailed account of its applications to the study of sedimentary rocks. The volume is a comprehensive, easily understood description of the applications of cathodoluminescence imaging to the study of sedimentary rocks. It will be an important resource for academic researchers, industry professionals and advanced graduate students in sedimentary geology.

Provides an introduction to petroleum exploration methods, referring to both geophysical and geochemical techniques and the logistics of various drilling techniques and well logging methods for oil and gas exploration. The second part of the book focuses on using these methods for petroleum exploration within the context of northern Africa. The geology of northern Africa is described and computerized lithographic correlation charts are presented and applied to petroleum exploration targets from the region.

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 and illustrate the potential applications of these methods. Heavily illustrated and lucidly written, this book will provide researchers and graduate students with the most current research on this important geological tool.
