Book Description
This book presents a summary of high-pressure phase transitions of minerals and related inorganic compounds. The first part reviews the methods to investigate phase transitions by direct high-pressure and high-temperature experiments together with thermodynamic approaches that consist of calorimetric measurements and thermodynamic calculation. In the second part, phase relations and thermodynamic properties of olivine, pyroxene, garnet, spinel, perovskite, rutile, and related inorganic compounds with A2BO4, ABO3, AB2O4, and AO2 stoichiometries are described. Particular emphasis is placed on spinel- and perovskite-structured phases and their high-pressure polymorphs called post-spinel and post-perovskite phases. The last part of the book focuses on phase relations of mantle rocks and on natural high-pressure minerals from the Earth’s deep mantle and in shocked meteorites.

Book Description
The relative importance of oxides in the field of materials science has been spectacularly increasing during the last twenty years. First the study of ferroelectrics kept the attention of scientists. Nevertheless this domain is far from being worked out and a lot of new results and of new fields of interest were recently discovered.

Book Description
Treatise on Geophysics, Second Edition, is a comprehensive and in-depth study of the physics of the Earth beyond what any geophysics text has provided previously. Thoroughly revised and updated, it provides fundamental and state-of-the-art discussion of all aspects of geophysics. A highlight of the second edition is a new volume on Near Surface Geophysics that discusses the role of geophysics in the exploitation and conservation of natural resources and the assessment of degradation of natural systems by pollution. Additional features include new material in the Planets and Moon, Mantle Dynamics, Core Dynamics, Crustal and Lithosphere Dynamics, Evolution of the Earth, and Geodesy volumes. New material is also presented on the uses of Earth gravity measurements. This title is essential for professionals, researchers, professors, and advanced undergraduate and graduate students in the fields of Geophysics and Earth system science. Comprehensive and detailed coverage of all aspects of geophysics Fundamental and state-of-the-art discussions of all research topics Integration of topics into a coherent whole

Book Description
Los óxidos de fórmula general RXO4, donde R es una tierra rara y X=P, As, V y Cr , forman una gran familia de compuestos que cristalizan con el tipo estructural zircón presentando simetría tetragonal, G.E. I41/amd o el polimorfo tipo monacita con simetría monoclínica, G.E. P21/n. La estabilidad de estos dos polimorfos depende de la relación de radios R3+/O-- y X/O--, de tal manera que la fase monacita se encuentra favorecida en los casos de la tierras raras de mayor tamaño; mientra que para las tierras raras de mayor número atómico la fase estable en condiciones normales es la tipo zircón. Los compuestos RXO4 localizados en la frontera entre estos dos polimorfos, presentan el fenómeno de polimorfismo y la estabilización de uno de ellos depende del método de síntesis seguido en su preparación. Así por ejemplo en el caso de la fase zircón correspondiente al TbPO4 se obtiene cuando se prepara a 1673K; mientras que, la fase monazita se aísla a temperaturas menores del orden de 1273 K. En el caso de los óxidos RCrO4 solo fase LaCrO4 cristaliza con el tipo estructural monacita debido al tamaño relativamente grande del ión La3+ en relación a las otras tierras raras. En el caso del siguiente miembro de la serie PrCrO4 en condiciones normales se obtienen mezclas de los dos polimorfos zircón y monacita. En el caso de la hipotética fase "CeCrO4" su síntesis no ha sido posible hasta el momento debido a la alta inestabilidad del Ce3+ en las condiciones requeridas para realizar la síntesis de estos compuestos...

Book Description
All existing introductory reviews of mineralogy are written accord ing to the same algorithm, sometimes called the "Dana System of Mineralogy". Even modern advanced handbooks, which are cer tainly necessary, include basic data on minerals and are essentially descriptive. When basic information on the chemistry, structure, optical and physical properties, distinguished features and para genesis of 200-400 minerals is presented, then there is practically no further space available to include new ideas and concepts based on recent mineral studies. A possible solution to this dilemma would be to present a book beginning where introductory textbooks end for those already famil iar with the elementary concepts. Such a volume would be tailored to specialists in all fields of science and industry, interested in the most recent results in mineralogy. This approach may be called Advanced Mineralogy. Here, an attempt has been made to survey the current possibilities and aims in mineral matter investigations, including the main characteristics of all the methods, the most important problems and topics of mineral ogy, and related studies. The individual volumes are composed of short, condensed chap ters. Each chapter presents in a complete, albeit condensed, form specific problems, methods, theories, and directions of investigations, and estimates their importance and strategic position in science and industry.
