This book was released on 1998 with total page 16 pages. Available in PDF, EPUB and Kindle. Book excerpt: Teleseismic receiver functions are used to estimate the crustal structure beneath a 36-station, 500-km-long, NW oriented linear array centered on the eastern Snake River Plain and crossing the Yellowstone hotspot swell 250 km SW of Yellowstone. Structure derived previously for this region from wide-angle reflection data is used as an initial model, and this structure explains most features observed in our receiver functions. Based on a combination of forward and inverse modeling, our data require several modifications to the initial structure: (1) Moho depth is ~42 km beneath most of the Snake River Plain, shallows to ~37 km to either side, and thickens abruptly to ~47 km beneath SW Wyoming; (2) a midcrustal layer interpreted previously as a ~9-km-thick gabbroic sill is flat topped across the entire ~90 km width of the Snake River Plain; and (3) a low-velocity layer is found beneath and southeast of the Snake River Plain, which probably is partially molten lower-most crust. Using the seismic structure of the crust to estimate the crustal load upon the mantle, and assuming local isostasy, we calculate that mantle beneath the Yellowstone swell is approximately uniformly as buoyant as 12-million-year-old ocean mantle, and more buoyant than the adjacent Wyoming mantle by an amount equivalent of ~1.5 km of elevation. The transition between these regions of greatly different mantle occurs across a major Paleozoic boundary that now separates the Basin and Range from the Rocky Mountains.
Download or read book Crustal Architecture of the Snake River Plain Idaho Through Geochemical Investigation of Crustal Sill and Shallow Subvolcanic Xenoliths written by Douglas James Jones and published by . This book was released on 2016 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The Snake River Plain (SRP) in southern Idaho is one of the best preserved examples of continental hotspot tracks. A layered mafic intrusion has been seismically imaged in the mid-crust, however, few geochemical studies have investigated the midcrustal sill complex0́9s importance in the evolution of SRP magmas. This thesis investigates the geochemistry of 3 xenoliths from a mid-to-lower crustal sill complex sampled from core taken from Kimama, ID, and 3 xenoliths from a shallow sub-volcanic magma chamber beneath the SRP sampled from Sid Butte, ID. Forward modeling and partition coefficient calculations estimate the parent melt of the Sid Butte xenoliths was a Snake River Plain olivine tholeiite magma and the parent melt of the Kimama xenoliths was an evolved Craters of the Moon (COM) type S magma. Geobarometic estimates constrain the Sid Butte xenoliths origin to a shallow magma chamber at ~3.3 km and the Kimama xenoliths in a mid-to-lower crustal sill complex at ~22 km. Kimama xenoliths have average Îþ18O of 5.42, indicating mantle origin and little-to-no assimilation of felsic country rock. The presence of COM-type magmas in a mid-to-lower crustal sill complex that have assimilated little-to-no crustal material indicate that fractionation processes alone can produce evolved basaltic magmas in the subsurface of the SRP. This is in contrast with theories that require a substantial amount of assimilation of felsic material for the generation of evolved COM-type magmas in the SRP. This thesis not only provides a better understanding of the crustal architecture of the SRP, it provides evidence for the importance of crustal sill complexes and shallow subvolcanic magma chambers in the evolution of SRP basalts.

Download or read book Dynamics of Crustal Magma Transfer Storage and Differentiation written by Catherine Annen and published by Geological Society of London. This book was released on 2008 with total page 300 pages. Available in PDF, EPUB and Kindle. Book excerpt: Magmas are subject to a series of processes that lead to their differentiation during transfer through and storage within the Earth's crust. The depths and mechanisms of differentiation, the crustal contribution to magma generation through wall-rock assimilation, the rates and timescales of magma generation, transfer and storage, and how these link to the thermal state of the crust are subject to vivid debate and controversy. This volume presents a collection of research articles that provide a balanced overview of the diverse approaches available to elucidate these topics, and includes both theoretical models and case studies. By integrating petrological, geochemical and geophysical approaches, it provides new insights to the subject of magmatic processes operating within the Earth's crust, and reveals important links between subsurface processes and volcanism.
Download or read book Fundamentals of Geomorphology written by Richard John Huggett and published by Routledge. This book was released on 2011-03-15 with total page 909 pages. Available in PDF, EPUB and Kindle. Book excerpt: This extensively revised, restructured, and updated edition continues to present an engaging and comprehensive introduction to the subject, exploring the world’s landforms from a broad systems perspective. It covers the basics of Earth surface forms and processes, while reflecting on the latest developments in the field. Fundamentals of Geomorphology begins with a consideration of the nature of geomorphology, process and form, history, and geomorphic systems, and moves on to discuss: structure: structural landforms associated with plate tectonics and those associated with volcanoes, impact craters, and folds, faults, and joints process and form: landforms resulting from, or influenced by, the exogenic agencies of weathering, running water, flowing ice and meltwater, ground ice and frost, the wind, and the sea; landforms developed on limestone; and landscape evolution, a discussion of ancient landforms, including palaeosurfaces, stagnant landscape features, and evolutionary aspects of landscape change. This third edition has been fully updated to include a clearer initial explanation of the nature of geomorphology, of land surface process and form, and of land-surface change over different timescales. The text has been restructured to incorporate information on geomorphic materials and processes at more suitable points in the book. Finally, historical geomorphology has been integrated throughout the text to reflect the importance of history in all aspects of geomorphology. Fundamentals of Geomorphology provides a stimulating and innovative perspective on the key topics and debates within the field of geomorphology. Written in an accessible and lively manner, it includes guides to further reading, chapter summaries, and an extensive glossary of key terms. The book is also illustrated throughout with over 200 informative diagrams and attractive photographs, all in colour.

Download or read book Biogeochemistry of Wetlands written by K. Ramesh Reddy and published by CRC Press. This book was released on 2022-09-10 with total page 926 pages. Available in PDF, EPUB and Kindle. Book excerpt: The globally important nature of wetland ecosystems has led to their increased protection and restoration as well as their use in engineered systems. Underpinning the beneficial functions of wetlands are a unique suite of physical, chemical, and biological processes that regulate elemental cycling in soils and the water column. This book provides an in-depth coverage of these wetland biogeochemical processes related to the cycling of macroelements including carbon, nitrogen, phosphorus, and sulfur, secondary and trace elements, and toxic organic compounds. In this synthesis, the authors combine more than 100 years of experience studying wetlands and biogeochemistry to look inside the black box of elemental transformations in wetland ecosystems. This new edition is updated throughout to include more topics and provide an integrated view of the coupled nature of biogeochemical cycles in wetland systems. The influence of the elemental cycles is discussed at a range of scales in the context of environmental change including climate, sea level rise, and water quality. Frequent examples of key methods and major case studies are also included to help the reader extend the basic theories for application in their own system. Some of the major topics discussed are: Flooded soil and sediment characteristics Aerobic-anaerobic interfaces Redox chemistry in flooded soil and sediment systems Anaerobic microbial metabolism Plant adaptations to reducing conditions Regulators of organic matter decomposition and accretion Major nutrient sources and sinks Greenhouse gas production and emission Elemental flux processes Remediation of contaminated soils and sediments Coupled C-N-P-S processes Consequences of environmental change in wetlands# The book provides the foundation for a basic understanding of key biogeochemical processes and its applications to solve real world problems. It is detailed, but also assists the reader with box inserts, artfully designed diagrams, and summary tables all supported by numerous current references. This book is an excellent resource for senior undergraduates and graduate students studying ecosystem biogeochemistry with a focus in wetlands and aquatic systems.

Join the Random House Reader’s Circle for author chats and more. In boyhood, Louis Zamperini was an incorrigible delinquent. As a teenager, he channeled his defiance into running, discovering a prodigious talent that had carried him to the Berlin Olympics. But when World War II began, the athlete became an airman, embarking on a journey that led to a doomed flight on a May afternoon in 1943. When his Army Air Forces bomber crashed into the Pacific Ocean, against all odds, Zamperini survived, adrift on a foundering life raft. Ahead of Zamperini lay thousands of miles of open ocean, leaping sharks, thirst and starvation, enemy aircraft, and, beyond, a trial even greater. Driven to the limits of endurance, Zamperini would answer desperation with ingenuity; suffering with hope, resolve, and humor; brutality with rebellion. His fate, whether triumph or tragedy, would be suspended on the fraying wire of his will. Appearing in paperback for the first time—with twenty arresting new photos and an extensive Q&A with the author—Unbroken is an unforgettable testament to the resilience of the human mind, body, and spirit, brought vividly to life by Seabiscuit author Laura Hillenbrand.

Download or read book Vertebrate Paleontology in Utah written by David D. Gillette and published by Utah Geological Survey. This book was released on 1999 with total page 568 pages. Available in PDF, EPUB and Kindle. Book excerpt: The 52 papers in this vary in content from summaries or state-of-knowledge treatments, to detailed contributions that describe new species. Although the distinction is subtle, the title (Vertebrate Paleontology in Utah) indicates the science of paleontology in the state of Utah, rather than the even more ambitious intent if it were given the title “Vertebrate Paleontology of Utah” which would promise an encyclopedic treatment of the subject. The science of vertebrate paleontology in Utah is robust and intense. It has grown prodigiously in the past decade, and promises to continue to grow indefinitely. This research benefits everyone in the state, through Utah’s muse ums and educational institutions, which are the direct beneficiaries.
