Download Thermodynamics of Minerals and Melts Book in PDF, Epub and Kindle
Today large numbers of geoscientists apply thermodynamic theory to solu tions of a variety of problems in earth and planetary sciences. For most problems in chemistry, the application of thermodynamics is direct and rewarding. Geoscientists, however, deal with complex inorganic and organic substances. The complexities in the nature of mineralogical substances arise due to their involved crystal structure and multicomponental character. As a result, thermochemical solutions of many geological-planetological problems should be attempted only with a clear understanding of the crystal-chemical and thermochemical character of each mineral. The subject of physical geochemistry deals with the elucidation and application of physico-chemical principles to geosciences. Thermodynamics of mineral phases and crystalline solutions form an integral part of it. Developments in mineralogic thermody namics in recent years have been very encouraging, but do not easily reach many geoscientists interested mainly in applications. This series is to provide geoscientists and planetary scientists with current information on the develop ments in thermodynamics of mineral systems, and also provide the active researcher in this rapidly developing field with a forum through which he can popularize the important conclusions of his work. In the first several volumes, we plan to publish original contributions (with an abundant supply of back ground material for the uninitiated reader) and thoughtful reviews from a number of researchers on mineralogic thermodynamics, on the application of thermochemistry to planetary phase equilibria (including meteorites), and on kinetics of geochemical reactions.

Download The Role of Volatiles in the Genesis, Evolution and Eruption of Arc Magmas Book in PDF, Epub and Kindle
The subduction zone volatile cycle is key to understanding the petrogenesis, transport, storage and eruption of arc magmas. Volatiles control the flux of slab components into the mantle wedge, are responsible for melt generation through lowering the solidi of mantle materials and influence the crystallizing phase assemblages in the overriding crust. Further, the rates and extents of degassing during magma storage and decompression affect magma rheology, ultimately control eruption style and have consequences for the environmental impact of explosive arc volcanism. This book highlights recent progress in constraining the role of volatiles in magmatic processes. Individual book sections are devoted to tracing volatiles from the subducting slab to the overriding crust, their role in subvolcanic processes and eruption triggering, as well as magmatic-hydrothermal systems and volcanic degassing. For the first time, all aspects of the overarching theme of volatile cycling are covered in detail within a single volume.

Download Volatiles in Magmas Book in PDF, Epub and Kindle
Volume 30 of Reviews in Mineralogy introduces in understanding the behavior of magmatic volatiles and their influence on a wide variety of geological phenomena; in doing this it also becomes apparent that there remain many questions outstanding. The range of topics we have tried to cover is broad, going from atomisticscale aspects of volatile solubility mechanisms and attendant effects on melt physical properties, to the chemistry of volcanic gases and the concentrations of volatiles in magmas, to the global geochemical cycles of volatiles. The reader should quickly see that much progress has been made since Bowen voiced his concerns about Maxwell demons, but like much scientific progress, answers to old questions have prompted even greater numbers of new questions. The Voltiles in Magmas course was organized and transpired at the Napa Valley Sheraton Hotel in California, December 2-4, 1994, just prior to the Fall Meetings of the American Geophysical Union in San Francisco.

Download Volatiles in the Martian Crust Book in PDF, Epub and Kindle
Volatiles in the Martian Crust is a vital reference for future missions - including ESA’s EXO Mars and NASA’s Mars2020 rover - looking for evidence of life on Mars and the potential for habitability and human exploration of the Martian crust. Mars science is a rapidly evolving topic with new data returned from the planet on a daily basis. The book presents chapters written by well-established experts who currently focus on the topic, providing the reader with a fresh, up-to-date and accurate view. Organized into two main sections, the first half of the book focuses on the Martian meteorites and specific volatile elements. The second half of the book explores processes and locations on the crust, including what we have learned about volatile mobility in the Martian crust. Coverage includes data from orbiter and in situ rovers and landers, geochemical and geophysical modeling, and combined data from the SNC meteorites. Presents information about the nature, relationship, and reactivity of chemical elements and compounds on Mars Explores the potential habitability of Mars Provides a comprehensive view of volatiles in the Martian crust from studies of actual samples as well as from the variety of landed missions, including the MER and Curiosity rovers Delivers a vital reference for ongoing and future missions to Mars while synthesizing large data sets and research on volatiles in the Martian atmosphere Concludes with an informative summary chapter that looks to future Mars missions and what might be learned

Download Variations in Volatiles in Magma Bodies Based on Studies of Melt Inclusions Book in PDF, Epub and Kindle
Knowledge of volatile concentrations in magmas are important in the prediction of explosive volcanism, and contribute to the understanding of the carbon dioxide budget of the atmosphere. Some important variables that are controlled by volatiles are: crystallization temperature of phases, composition of liquids minimum, and viscosity. Volatiles are also catalysts for reactions.

Download The Encyclopedia of Igneous and Metamorphic Petrology Book in PDF, Epub and Kindle
Featuring over 250 contributions from more than 100 earth scientists from 18 countries, The Encyclopedia of Igneous and Metamorphic Petrology deals with the nature and genesis of igneous rocks that have crystallized from molten magma, and of metamorphic rocks that are the products of re-crystallization associated with increases in temperature and pressure, mainly at considerable depths in the Earth's crust. Entries range from alkaline rocks to zeolite facies - providing information on the mineralogical, chemical and textural characters of rock types, the development of concepts and the present state of knowledge across the spectrum of igneous and metamorphic petrology, together with extensive lists of both commonly used and little used terms and bibliographies.

Download The Transfer of Volatiles Within Interacting Magmas and Its Effect on the Magma Mingling Process Book in PDF, Epub and Kindle
The input of volatile-charged mafic magma into chemically evolved felsic magma reservoirs in the shallow crust leads to the exchange of heat and chemical components that may serve as the trigger for subsequent volcanic eruption. The exchange of volatiles, which occurs via diffusion and potentially through fluid movement, is particularly important to this process. In order to simulate the magma mingling process and the role of volatiles within this process, we have conducted a series of hydrothermal experiments involving a hydrous basaltic-andesite glass containing trace olivine (prepared from a natural sample of Augustine volcano in Alaska's Aleutian Arc) with crystal-deficient, anhydrous or hydrous Los Posos rhyolite glass (also natural) at 100 MPa. Some experiments were conducted under fluid-absent conditions while others involved O-H-Cl±S-bearing fluids. Temperature was varied during these experiments, with most beginning at 1100°C. Temperature was subsequently reduced to 800°C in several steps, where it remained until an isobaric quench. The run durations ranged from 25 to 125 hours. The experimental products exhibit interesting textural and chemical features. The rhyolitic run product glass, whether hydrous or anhydrous initially, exhibits minimal crystallization throughout the experiments, whereas the starting basaltic-andesite glass shows significant crystallization of iron and titanium oxides, plagioclase, and pyroxene. The exchange of Cl between the two melts was significant for fluid-present and fluid-absent conditions, and the concentration of Cl in the more felsic melt was strongly controlled by well established Cl solubility relationships involving the cations Ca, Al, Na, and Mg and the presence or absence of S.
