Komatiites erupted billions of years ago as pulsating streams of white-hot lava. Their unusual chemical compositions and exceptionally high formation temperatures produced highly fluid lava that crystallized as spectacular layered flows. Investigation of the extreme conditions in which komatiites formed provides important evidence about the thermal and chemical evolution of the planet, and the nature of the Precambrian mantle. This monograph, written by three experts with long experience in the field, presents a complete account of the characteristics of komatiites including their volcanic structures, textures, mineralogy and chemical compositions. Models for their formation and eruption are evaluated (including the anhydrous vs. hydrous magmas controversy). A chapter is also devoted to the valuable nickel and copper ore deposits found in komatiites. Komatiite is a key reference for researchers and advanced students interested in petrology, Archaean geology, economic geology, and broader questions about the evolution of the Earth's crust and mantle.

textbook. Basic description is attempted, and the bibliography has been specifically chosen to guide the reader toward a fuller treatment of his special ised interests. No fully satisfactory term has yet emerged to describe the processing of minerals, which is also called "ore dressing," "mineral dressing," "mineral engineering" and, in the University of London degree course "mineral technology." The dressing of ores was an excellent description of the older processes which aimed to break down rock to appropriate sizes, grade it, and separate the heavy fraction from the light one in each grade or size by gravity methods. The work done in the mill today goes far beyond these simple operations, and requires some knowledge of physical chemistry, particularly the branches which deal with the physics and chemistry of surfaces and of the interphase between solid particle and the surrounding liquid. At the same time, the engineer must not become so absorbed in the study of fundamental and applied technology as a physico-chemical science that he overlooks the mechanical, economic, and humanistic aspects oli his work. He is an engineer, a chemist, a physicist, and an administrator and, as such, should have a sound scientifj. c and cultural education. Technically, his work is to extract the valuable minerals from the ore sent to his mill; economically, it is to balance all the financial costs and returns in such a way as to ensure the maximum profit from the operation."

The key for identification of rock-forming minerals provides an efficient and systematic approach to identifying minerals in thin-section. It is structured in the form of a dichotomous key, comparable to those widely used in botany and entomology. Whilst some previous mineralogy and petrology texts have produced tabulated summaries of minerals with similar properties, the present key gives a unique solution for each mineral.
The key covers more than 150 of the most commonly encountered rock-forming minerals, plus a few rarer but noteworthy minerals, indicative of particular conditions. Illustrated in full colour, with high quality photomicrographs of each mineral, it also provides the most comprehensive atlas of rock-forming minerals currently available. It is primarily aimed at undergraduate and postgraduate students of mineralogy and petrology, but should also provide a valuable source of reference for all practising geologists dealing with rock thin-sections and their interpretation.
Although including a brief introduction to the properties of minerals in this-section, the key largely assumes that the user has a basic understanding of optical mineralogy and is able to determine basic mineral properties in thin-section using plane-polarised and cross-polarised light. The key has been designed in such a way as to prioritise those properties that are most easily defined, and thus less ambiguous. This aims to minimise the chance of misidentification and enable the less experienced petrologist to use the key with confidence. The key has been carefully designed to enable different cuts of minerals (e.g. end-section and side sections) to be recognised and keyed out.

In this book you will find a lot of exciting and often astonishing information about these extraordinary and diverse materials. The presentation is essentially structured chronologically and follows the history of the discovery of these materials. Their properties and areas of application are described. The book is a mixture of specialist and non-fiction: understandable for experts and laypeople. This book is a translation of the original German 1st edition Zirkon, Zirkonium, Zirkonia - ahnliche Namen, verschiedene Materialien by Bozena Arnold, published by Springer-Verlag GmbH Germany, part of Springer Nature in 2019. The translation was done with the help of artificial intelligence (machine translation by the service DeepL.com). A subsequent human revision was done primarily in terms of content, so that the book will read stylistically differently from a conventional translation. Springer Nature works continuously to further the development of tools for the production of books and on the related technologies to support the authors.

From the nano-world of rusty proteins and magnetic compasses in bacteria to the macroscopic structures of oyster shells, corals, ivory, bone and enamel, biology has evolved a new type of chemistry that brings together the synthesis and construction of hard and soft matter for the design of functionalized inorganic-organic materials. The process that gives rise to these small and large inorganic-based structures of life is called biomineralization. This book looks at the chemical principles and concepts of biomineralization and their application in the new field of biomimetic materials chemistry.

Many common terms in metamorphic petrology vary in their usage and meaning between countries. The International Union of Geological Sciences (IUGS) Subcommission on the Systematics of Metamorphic Rocks (SCMR) has aimed to resolve this, and to present systematic terminology and rock definitions that can be used worldwide. This 2007 book is the result of discussion and consultation lasting 20 years and involving hundreds of geoscientists worldwide. It presents a complete nomenclature of metamorphic rocks, with a comprehensive glossary of definitions, sources and etymology of over 1200 terms, and a list of mineral abbreviations. Twelve multi-authored sections explain how to derive the correct names for metamorphic rocks and processes, and discuss the rationale behind the more important terms. These sections deal with rocks from high- to low- and very-low-grade. This book will form a key reference and international standard for all geoscientists studying metamorphic rocks.

Direct methods are, at present, applied to a large variety of cases: X-ray, neutron or electron data; single crystal and powder data; small molecules and macromolecules. While direct methods solved in practice the phase problem for small molecules, their application to macromolecules is recent and still undergoing strong development. The fundamentals of the methods are described: in particular it is shown how the methods can be optimized for powder, neutron or electron data, and how they can be integrated with isomorphous replacement, molecular replacement and anomalous dispersion techniques. Maximum Entropy methods are also described and discussed. Sets of test structures are used to verify, throughout the various chapters, the mathematical techniques there described and to provide practical examples of applications. This book will appeal to a wide variety of readers - offering both a comprehensive description of direct methods in crystallography and an invaluable reference tool. The first three chapters can be considered as an introduction to the field, with sufficient material to constitute a university course and for allowing the expert use of most direct methods programs. Subsequent chapters are aimed at graduate students and working crystallographers. Basic results are described and discussed in the main body of the text, while the appendices compliment these with in depth mathematical details. The quoted literature is extremely wide and the interested reader can find suggestions for future work and further reading throughout the book.

Physics Meets Mineralogy: Condensed Matter Physics in the Geosciences describes the interaction between geophysics and condensed matter physics. Condensed matter physics leads to a 'first-principles' way of looking at crystals, enabling physicists and mineralogists to study the rich and sometimes unexpected behaviour that minerals exhibit under the extreme conditions, such as high pressure and high temperature, found deep within the earth. Leading international researchers from both geosciences and condensed matter physics discuss this interdisciplinary field. An excellent summary for specialists and graduate students researching mineralogy and crystallography.

This book focuses on the geological characteristics and genesis of several base metal deposits in the northern margin of the North China Plate, namely the Bainaimiao Cu-Au-Mo, the Huogeqi Cu-Pb-Zn, the Dongshengmiao Zn-Pb-Cu and the Jiashengpan Zn-Pb deposits. These deposits have geological and geochemical affinities with orogenic-type deposits, such as shear zone-controlled mineralization and carbon-rich low-salinitiy ore-forming fluids, and are characterized by multistage ore-forming histories. Remobilization of the pre-enriched (stratabound or porphyry-type) base metals took place as responses to orogenesis and metamorphism, leading to metal redistribution and the formation of orogenic-type orebodies. The formation of orogenic-type base metal deposits is enigmatic, and the case studies presented in this book provide insights into understanding the genesis of this type of deposits. In particular, pre-enrichment of base metals seems to be important, in terms of preconditioning for later shear zone-controlled mineralization, since base metals are believed to have limited solubilities in the low-salinity ore-fluids.
