Melt Inclusions in Volcanic Systems


Book Description

Melt inclusions provide a unique record of the physical and chemical processes operating in active magma chambers associated with volcanic systems. This book includes a summary of modern techniques used to study and interpret melt inclusions in volcanic rocks, as well as descriptive studies of specific volcanoes. These various studies document the enormous potential for melt inclusions to provide a window into the dynamics of active magma chambers.'Melt Inclusions in Volcanic Systems' gives the most up-to-date summary of research on the application of melt inclusions in studies of active and fossil volcanic systems, as well as suggestions for future research in this area.




Magmatic Systems


Book Description

With its integrated and cohesive coverage of the current research, Magmatic Systems skillfully explores the physical processes, mechanics, and dynamics of volcanism. The text utilizes a synthesized perspective--theoretical, experimental, and observational--to address the powerful regulatory mechanisms controlling the movement of melts and cooling, with emphasis on mantle plumes, mid-ocean ridges, and intraplate magmatism. Further coverage of subduction zone magmatism includes:Fluid mechanics of mixed magma migrationInternal structure of active systemsGrain-scale melt flowRheology of partial meltsNumerical simulation of porous media melt migrationNonlinear (chaotic and fractal) processes in magma transportIn all, Magmatic Systems will prove invaluable reading to those in search of an interdisciplinary perspective on this active topic.Key Features* Fluid mechanics of magma migration from surface region to eruption site* Internal structure of active magmatic systems* Grain-scale melt flow in mantle plumes and beneath mid-ocean ridges* Physics of magmatic systems and magma dynamics




Minerals, Inclusions And Volcanic Processes


Book Description

Volume 69 of Reviews in Mineralogy and Geochemistry covers the fundamental issues of volcanology: At what depths are eruptions triggered, and over what time scales? Where and why do magmas coalesce before ascent? If magmas stagnate for thousands of years, what forces are responsible for initiating final ascent, or the degassing processes that accelerate upward motion? To the extent that we can answer these questions, we move towards formulating tests of mechanistic models of volcanic eruptions (e.g., Wilson, 1980; Slezin, 2003; Scandone et al., 2007), and hypotheses of the tectonic controls on magma transport (e.g., ten Brink and Brocher, 1987; Takada, 1994; Putirka and Busby, 2007). Our goal, in part, is to review how minerals can be used to understand volcanic systems and the processes that shape them; we also hope that this work will spur new and integrated studies of volcanic systems.




Fluid inclusions


Book Description

Volume 12 of Reviews in Mineralogy introduces to fluid inclusions. It covers the folowing questions: when and where inclusions form. how they change, how to prepare material and make microthermometric measurementsl, how to interpret these data, and what has been found in applications of fluid-inclusion studies to each of a series of different geologic environments. This book also attempts to discuss the many applications of fluid inclusions to the study of and understanding of geologic processes and the geologic environments in which they acted.










The Role of Volatiles in the Genesis, Evolution and Eruption of Arc Magmas


Book Description

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.




Fluid-Fluid Interactions


Book Description

Volume 65 of Reviews in Mineralogy and Geochemistry attempts to fill this gap and to explicitly focus on the role that co-existing fluids play in the diverse geologic environments. It brings together the previously somewhat detached literature on fluid–fluid interactions in continental, volcanic, submarine and subduction zone environments. It emphasizes that fluid mixing and unmixing are widespread processes that may occur in all geologic environments of the entire crust and upper mantle. Despite different P-T conditions, the fundamental processes are analogous in the different settings.







Geofluids


Book Description

Geofluids: Developments in Microthermometry, Spectroscopy, Thermodynamics, and Stable Isotopes is the definitive source on paleofluids and the migration of hydrocarbons in sedimentary basins—ideal for researchers in oil and gas exploration. There's been a rapid development of new non-destructive analytical methods and interdisciplinary research that makes it difficult to find a single source of content on the subject of geofluids. Geoscience researchers commonly use multiple tools to interpret geologic problems, particularly if the problems involve fluid-rock interaction. This book perfectly combines the techniques of fluid inclusion microthermometry, stable isotope analyses, and various types of spectroscopy, including Raman analysis, to contribute to a thorough approach to research. Through a practical and intuitive step-by-step approach, the authors explain sample preparation, measurements, and the interpretation and analysis of data related to thermodynamics and mineral-fluid equilibria. - Features working examples in each chapter with step-by-step explanations and calculations - Broad range of case studies aid the analytical and experimental data - Includes appendices with equations of state, stable isotope fractionation equations, and Raman identification tables that aid in identification of fluid inclusion minerals - Authored by a team of expert scientists who have more than 60 years of related experience in the field and classroom combined
