Book Description
This book highlights various aspects of geochemical and geological processes. In brief, it facilitates to understand the geochemical behavior of major, trace and rare earth elements in rocks to identify the magmatic processes involved in present-day magma generation and their relation to global tectonic regimes as well as geothermal studies. Therefore, the book provides a comprehensive view of the generation of magma types (mafic to felsic in composition) and their role in the petrogenesis. The book also covers the development of new geosoftware to effectively process the geochemical data before its interpretation.

Book Description
Volume 50 of Reviews in Mineralogy and Geochemistry treats Beryllium and its cosmogenic isotopes. This volume includes an overview of Be studies in the earth sciences and a systematic classification of Be minerals based on their crystal structure. It treats the analysis of these minerals by the secondary ion mass spectroscopy as well as experimental studies of systems involving Be. Moreover, this volume reviews the behavior of Be in the Solar System, with an emphasis on meteorites, the Moon and Mars, and the implications of this behavior for the evolution of the solar system. It gives an overview of the terrestrial geochemistry of Be and discusses the contamination of the environment by this anthropogenic toxin. It reports use of the longer lived Be-10 to assess erosion rates and other surficial processes and how this isotope can yield independent temporal records of geomagnetic field variations for comparison with records obtained by measuring natural remnant magnetization, be a chemical tracer for processes in convergent margins, and can date events in Cenozoic tectonics. It reviews applications of the shorter lived isotope Be-7 in environmental studies as well. Residual phases include acidic plutonic and volcanic rocks, whose geochemistry and evolution are covered, while granitic pegmatites, which are well-known for their remarkable, if localized, Be enrichments and a wide variety of Be mineral assemblages, are reviewed. Not all Be concentrations have obvious magmatic affinities; for example, one class of emerald deposits results from Be being introduced by heated brines. Pelitic rocks are an important reservoir of Be in the Earth's crust and their metamorphism plays a critical role in recycling of Be in subduction zones, eventually, anatectic processes complete the cycle, providing a source of Be for granitic rocks.

Book Description
The first edition of this book has been out of print for seven years. The ques tion as to whether a new edition should be produced was answered affirmatively on many counts. I think that the considerations which led me to write this book in 1949 are still valid (see Preface to the First Edition). Moreover, a description of those areas of interest which together comprise the field of Mineralogy seems to be more necessary than ever, because of the rapid advances which have been made. Due to the rapid extension of our knowledge, I did not dare again to treat the whole field by myself. Accordingly, Professor ZEMANN kindly agreed to revise the first part of the book dealing with Crystallography. He made many important corrections. In Part II the basic question arose as to whether the physical-chemical approach to rock forming processes, becoming more and more important, required inclusive treatment of the fundamentals of physical chemistry in the book. I see certain dangers in trying to produce a petrology text which is physical chemically self-sufficient. Thus, I retain the same opinion which prevailed when I wrote the previous edition; namely that the necessary basic knowledge should be acquired in lectures and laboratory classes in physics, chemistry, and physical chemistry, and with the help of standard literature dealing with these subjects. This back ground is, therefore, presumed and fundamentals are only referred to occasionally.

Book Description
Handbook of Exploration Geochemistry, Volume I: Analytical Methods in Geochemical Prospecting focuses on the principles, methodologies, approaches, and techniques employed in geochemical prospecting. The book first underscores quality control in the laboratory, sample preparation, sample decomposition-solution techniques, and colorimetry and related techniques. Discussions focus on colorimetry, turbidimetric methods, strong decompositions, partial extractions, preparation of rock samples, random and systematic errors, and quality control program. The publication then takes a look at atomic absorption spectrophotometry, emission spectroscopy, and X-ray fluorescence. Concerns cover instrumentation, operation of the X-ray fluorescence spectrometer, flame emission spectroscopy, semi-quantitative DC-arc spectroscopy, and plasma sources. The text examines electrochemical methods, including determination of pH and specific ion electrodes. The publication is a dependable reference for researchers interested in the analytical methods in geochemical prospecting.

Book Description
'What are we going to do with a parcel of old stones?' wrote the director of an African museum a century and a half ago, when one of my ancestors presented him with a splendid collection of fossils of mammal-like reptiles. Old stones, however intriguing, are difficult to interpret, dusty, and do not fit well in the neatly ordered contents of a house of learning. Archaean geology, which is the study of the Earth's history in the period from after 9 the end of planetary accretion (4.5-4.4 x 10 years ago) up to the beginning 9 of the Proterozoic (2.5 x 10 years ago) is much the same - a parcel of old stones seemingly impossible to understand. Yet these stones contain the history of our origins: they can tell us a story that is interesting not just to the geologist (for whom this book is primarily written) but instead addresses the human condition in general.

Book Description
Provides an up-to-date introduction to the subject of ore microscopy, emphasizing the basic skills required for the study of opaque minerals in polished sections. Describes the modern ore microscope, the preparation of polished and polished-thin sections of opaque minerals and ores, and the identification of these minerals using both qualitative techniques and the quantitative methods of reflectance and microhardness measurement. Later sections discuss the interpretation of textural intergrowths of ore minerals and the determination of their paragenesis, along with the examination of coexisting minerals for determining their physio-chemical conditions of formation. Appendices contain the data necessary to identify approximately 100 of the more common ore minerals and those frequently encountered by the professional scientist.

Book Description
The nature and origin of the small-scale volcanic systems, generally referred to as 'monogenetic', have enjoyed an elevated level of interest during the past decade. There has been recognition that their ostensibly simple volcano types are a window into the nature of explosive volcanism, landscape evolution and the processes of magma generation in the Earth’s upper mantle. In the past few years, major conferences have offered specialized technical sessions dealing with monogenetic volcanism and there have been thematic conferences, such as the IAVCEI International Maar Conference series, which have provided a focus for discussion of volcanological and geochemical aspects of small-scale basaltic volcanism. Many new aspects of monogenetic volcanism have emerged and have clearly demonstrated that this volcanism can be very complex on a fine scale. This book is a collection of papers arising from two recent Maar Conferences (the fifth in Queretaro Mexico and the sixth in Changchun, China) and serves as a snapshot of current research on monogenetic volcanism.
