Phase Diagrams for Geoscientists


Book Description

The book summarizes the author's experimental studies of phase relations in the chemical systems relevant to Earth, carried out in a time period of over 20 years using piston-cylinder and multi-avil presses. A summary of the research at high pressures and temperatures carried out by many other experimental petrologists is also included. The data was used to develop an internally consistent thermodynamic model, which was then used to calculate phase diagrams. This produced the largest collection of the calculated phase diagrams published so far, encompassing for the first time the temperature and pressure ranges corresponding to the whole upper mantle.

Phase Diagrams for Geoscientists


Book Description

The book summarizes the results of the experimental studies of phase relations in the chemical systems relevant to Earth, carried out by the author in a time period of over 20 years between 1979 and 2001. It is based on 1000 piston-cylinder experiments at pressures up to 4 GPa, and close to 700 experiments carried out with a multi-anvil apparatus at pressures up to 24 GPA. This is the largest published collection of calculated phase diagrams for the chemical systems relevant to Earth. This is also the first time that the phase relations at the relatively low pressures of the lithospheric mantle, mainly applicable to the experimental thermobarometry of metamorphic rocks and mantle xenoliths, are seamlessly integrated with the phase relations of the sublithospheric upper mantle and the uppermost lower mantle, primarily applicable to inclusions in diamond and schocked meteorites. "Tibor Gasparik has devoted his career to determining the high-pressure, high-temperature phase relations of the geologically important Sodium-Calcium-Magnesium-Aluminium-Silicon (NCMAS) oxide system. This book is his opus magnum, summarizing more than 1700 experiments in over 120 figures. ... I have found Phase Diagrams for Geoscientists to be a useful first port-of-call for finding the P-T stability fields ... and I can recommend the book as a reference for geoscientists requiring an overview of the stable phase assemblages in the top 700 km of the Earth."

Methods for Phase Diagram Determination


Book Description

Phase diagrams are "maps" materials scientists often use to design new materials. They define what compounds and solutions are formed and their respective compositions and amounts when several elements are mixed together under a certain temperature and pressure. This monograph is the most comprehensive reference book on experimental methods for phase diagram determination. It covers a wide range of methods that have been used to determine phase diagrams of metals, ceramics, slags, and hydrides.* Extensive discussion on methodologies of experimental measurements and data assessments * Written by experts around the world, covering both traditional and combinatorial methodologies* A must-read for experimental measurements of phase diagrams




Practical Chemical Thermodynamics for Geoscientists


Book Description

-- Presents brief historical summaries and biographies of key thermodynamics scientists alongside the fundamentals they were responsible for.




Minerals


Book Description

The new edition of this popular textbook, once again, provides an indispensable guide for the next generation of mineralogists. Designed for use on one- or two-semester courses, this second edition has been thoughtfully reorganised, making it more accessible to students, whilst still being suitable for an advanced mineralogy course. Additions include expanded introductions to many chapters, a new introductory chapter on crystal chemistry, revised figures, and an extended plates section containing beautiful colour photographs. Text boxes include historical background and case studies to engage students, and end-of-chapter questions help them reinforce concepts. With new online resources to support learning and teaching, including laboratory exercises, PowerPoint slides, useful web links and mineral identification tables, this is a sound investment for students in the fields of geology, materials science and environmental science, and a valuable reference for researchers, collectors and anyone interested in minerals.




Equilibrium Between Phases of Matter


Book Description

The Second Volume of “Equilibrium between Phases of Matter”, when compared with the First Volume, by H.A.J. Oonk and M.T. Calvet, published in 2008, amounts to an extension of subjects, and a deepening of understanding. In the first three sections of the text an extension is given of the theory on isobaric binary systems. The fourth section gives an account of the thermodynamic analyses of four isobaric binary key systems, highlighting the power of empirical, (exo)thermodynamic correlations. The fifth section is devoted to the thermodynamic description of ternary systems. The last three sections concentrate on the properties of materials, and the phase behaviour of systems under the conditions of high temperature and high pressure – conditions that prevail in the interior of the Earth. A new equation of state is the subject of the sixth section. In the seventh section a move is made to statistical thermodynamics and vibrational models; the description of the systems has changed from mathematical to physical. The last section is on the system MgO – SiO2, looked upon from a geophysical point of view. Throughout the work high priority is given to the thermodynamic assessment of experimental data; numerous end-of-section exercises and their solutions are included. Along with the First Volume, the work is useful for materials scientists and geophysicists as a reference text. Audience Volume II is a lecture book for postgraduate students in chemistry, chemical engineering, geology and metallurgy. It is highly useful as a recommended text for teachers and researchers in all fields of materials science.




Road from Geochemistry to Geochemometrics


Book Description

This book highlights major problems in the statistical analysis of compositions that have been known for over a century, as well as the corresponding solutions that have been put forward by specialists over the past 30 years. The basic assumptions of normality or multi-normality are pointed out and methods to test and achieve them are also covered. The conventional major and trace element geochemistry and modeling equations are discussed, and are followed by a more sophisticated multidimensional approach to data handling. The book’s main focus is on the use of statistical techniques to facilitate data interpretation. It also highlights the classification (or nomenclature) and tectonic discrimination aspects for both igneous and sedimentary rocks. The book concludes by discussing computer programs that are helping pave the way from geochemistry to geochemometrics. Written by a leading expert in the area of geochemistry, it offers a valuable guide for students and professionals in the area.




Crust-Mantle and Lithosphere-Asthenosphere Boundaries


Book Description

This 10-chapter volume encompasses contributions from a wide spectrum of Earth science disciplines, including geophysics, geodynamics, geochemistry, and petrology, to provide an overview of the nature and evolution of the crust-mantle and lithosphere-asthenosphere boundaries in different tectonic settings, combining studies that exploit different types of data and interpretative approaches. The integration of geochemical, geophysical, and geodynamic data sets and their interpretation provides a state-of-the-art summary of current understanding, and will serve as a blueprint for future research activities.
