This book was released on 2018-12-17 with total page 632 pages. Available in PDF, EPUB and Kindle. Book excerpt: Volume 32 of Reviews in Mineralogy introduces the basic concepts of melt physics and relaxation theory as applied to silicate melts, then to describe the current state of experimental and computer simulation techniques for exploring the detailed atomic structure and dynamic processes which occur at high temperature, and finally to consider the relationships between melt structure, thermodynamic properties and rheology within these liquids. These fundamental relations serve to bridge the extrapolation from often highly simplified melt compositions studied in the laboratory to the multicomponent systems found in nature. This volume focuses on the properties of simple model silicate systems, which are usually volatile-free. The behavior of natural magmas has been summarized in a previous Short Course volume (Nicholls and Russell, editors, 1990: Reviews in Mineralogy, Vol. 24), and the effect of volatiles on magmatic properties in yet another (Carroll and Holloway, editors, 1994: Vol. 30). The Mineralogical Society of America sponsored a short course for which this was the text at Stanford University December 9 and 10, 1995, preceding the Fall Meeting of the American Geophysical Union and MSA in San Fransisco, with about 100 professionals and graduate students in attendance.

Available in PDF, EPUB and Kindle. Book excerpt: Characterization of the relationships between structure and properties of materials is based on the fundamental principle that the structure of the material be determined first, followed by assessments of which structural properties may govern their properties as a function of composition, pressure, temperature and other variables. Whereas this methodology has been successfully applied to further our understanding of crystalline materials, studies of silicate melt structure are often conducted on a somewhat different basis. Rather than from direct structural determination, structure models have been developed from assumed relationships between a specific melt property and its structure. As a result, a multitude of models has evolved - many of which are mutually exclusive. The overall scope of this book is to address properties and processes of magmatic systems from the vantage point of melt structure. To this end available data in chemically increasingly complex systems are reviewed and discussed with the ultimate goal being integration of the simple system data into a model that describes complex systems such as natural magmatic liquids. Thus the book evolves from the simplest possible system, SiO 2 , to complex systems such as natural magmatic liquids. From a petrologic point of view, sufficient data have been obtained so that a general framework of the structure of magmatic liquids is in place. This framework is based on the same principles as those of crystal chemistry, modulated by the absence of long range order in amorphous material, and systematic relationships between structure and properties can be discerned at least at atmospheric pressure.

Download or read book Carbon in Earth's Interior written by Craig E. Manning and published by John Wiley & Sons. This book was released on 2020-04-03 with total page 373 pages. Available in PDF, EPUB and Kindle. Book excerpt: Carbon in Earth's fluid envelopes - the atmosphere, biosphere, and hydrosphere, plays a fundamental role in our planet's climate system and a central role in biology, the environment, and the economy of earth system. The source and original quantity of carbon in our planet is uncertain, as are the identities and relative importance of early chemical processes associated with planetary differentiation. Numerous lines of evidence point to the early and continuing exchange of substantial carbon between Earth's surface and its interior, including diamonds, carbon-rich mantle-derived magmas, carbonate rocks in subduction zones and springs carrying deeply sourced carbon-bearing gases. Thus, there is little doubt that a substantial amount of carbon resides in our planet's interior. Yet, while we know it must be present, carbon's forms, transformations and movements at conditions relevant to the interiors of Earth and other planets remain uncertain and untapped. Volume highlights include: - Reviews key, general topics, such as carbonate minerals, the deep carbon cycle, and carbon in magmas or fluids - Describes new results at the frontiers of the field with presenting results on carbon in minerals, melts, and fluids at extreme conditions of planetary interiors - Brings together emerging insights into carbon's forms, transformations and movements through study of the dynamics, structure, stability and reactivity of carbon-based natural materials - Reviews emerging new insights into the properties of allied substances that carry carbon, into the rates of chemical and physical transformations, and into the complex interactions between moving fluids, magmas, and rocks to the interiors of Earth and other planets - Spans the various chemical redox states of carbon, from reduced hydrocarbons to zero-valent diamond and graphite to oxidized CO2 and carbonates - Captures and synthesizes the exciting results of recent, focused efforts in an emerging scientific discipline - Reports advances over the last decade that have led to a major leap forward in our understanding of carbon science - Compiles the range of methods that can be tapped tap from the deep carbon community, which includes experimentalists, first principles theorists, thermodynamic modelers and geodynamicists - Represents a reference point for future deep carbon science research Carbon in Planetary Interiors will be a valuable resource for researchers and students who study the Earth's interior. The topics of this volume are interdisciplinary, and therefore will be useful to professionals from a wide variety of fields in the Earth Sciences, such as mineral physics, petrology, geochemistry, experimentalists, first principles theorists, thermodynamics, material science, chemistry, geophysics and geodynamics.

Download or read book Viscosities of Silicate Liquids at High Pressures written by Lara O'Dwyer Brown and published by . This book was released on 2012 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Silicate melt viscosity is a complex function of composition, temperature and pressure. This dissertation addresses the compositional and pressure dependences of silicate melt viscosity by providing new experimental data on three compositions over a range of pressures. In Chapter 1 I provide critical background, which summarizes the extent of our knowledge of silicate melt viscosity at high pressure, and effectively highlights the outstanding gaps in our knowledge. Each subsequent chapter presents the new experimental data, which are combined with available experimentally determined viscosities, structural information and molecular dynamics simulations, thus linking theory, models and experiments. In Chapter 2 I present a series of experiments on lithium disilicate melt viscosity between 1 and 6 GPa. Using these data I investigate the transition from negative to positive pressure dependence in polymerized systems. Specifically, I address the relationship between composition and the pressure of viscosity minima. Chapter 3 provides extensive details on the falling sphere experimental method. To address the pressure dependence of depolymerized silicate melt viscosities at high pressures I present the viscosities of two komatiites between 1 and 10 GPa. Using these new data I systematize the relationship between pressure and viscosity in depolymerized systems and propose a model that reproduces the observed pressure dependences of viscosity for a range of compositions up to 10 GPa. In Chapter 4 the measured pressure range of molten komatiite viscosities is extended to 13.5 GPa. Based on these new data I develop a new model for depolymerized melts in terms of the fundamental parameter activation volume. This model is used to predict the viscosity of the Earth's magma ocean. Finally, each of the Appendices addresses an experimental detail including pressure and temperature determination, methods for measuring density, and an assessment of the falling sphere technique using numerical simulations.

Available in PDF, EPUB and Kindle. Book excerpt: During the last few years, carbonatites have received a considerable amount of attention. Some of this interest was no doubt kindled by the importance of volatiles in the Earth's mantle, particularly CO , by the fact that carbonatites 2 can be used to monitor the chemical evolution of the sub-continental upper mantle, and by the fact that carbonatites may be effective metasomatizing agents at both mantle and crustal levels. The interest in Oldoinyo Lengai has extended over at least 100 years, but it was not until the eruptions of 1960, when the unique carbonatitic nature of its lavas was recognized, that the volcano took on special significance in volcanology and igneous petrology. The recognition of carbonatitic flows coin cided with the first successful laboratory experiments carried out on carbonatitic melts. Since then, Oldoinyo Lengai has formed a cornerstone in all carbonatite discussions. It is probably true to say that the findings from Oldoinyo Lengai have dominated our ideas about carbonatites, in spite of the fact that the alkali rich, natrocarbonatitic lavas of Oldoinyo Lengai are markedly different from other carbonatites.
Download or read book Energetics of Silicate Melts from Thermal Diffusion Studies. Final Report written by and published by . This book was released on 2001 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Initially this project was directed towards exploiting Soret diffusion of silicate liquids to learn about the internal energetics of the constituents of the liquids. During the course of this project this goal was realized at the same time a series of intellectual and technical developments expanded the scope of the undertaking. Briefly recapping some of the highlights, the project was initiated after the discovery that silicate liquids were strongly Soret-active. It was possible to observe the development of strong diffusive gradients in silicate liquid composition in response to laboratory-imposed thermal gradients. The character of the chemical separations was a direct window into the internal speciation of the liquids; the rise time of the separation was a useful entree to quantitatively measuring chemical diffusivity; and the steady state magnitude of the separation proved to be an excellent determinant of the constituents' mixing energies. A comprehensive program was initiated to measure the separations, rise times, and mixing energies of a range of geologically and technically interesting silicate liquids. An additional track of activities in the DOE project has run in parallel to the Soret investigation of single-phase liquids in a thermal gradient. This additional track is the study of liquid-plus-crystal systems in a thermal gradient. In these studies solubility-driven diffusion introduced many useful effects, some quite surprising. In partially molten silicate liquids the authors applied their experiments to understanding magmatic cumulate rocks. They have also applied their understanding of these systems to aspects of evaporite deposits in the geological record. They also undertook studies of this sort in systems with retrograde solubility in order to form the basis for understanding remediation for brine migration problems in evaporite-hosted nuclear waste repositories such as the WIPP.
