This book was released on 2019 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The 1~9-km-thick sequence inter~ected by the IRDP 1978 drill hole at Reydarfjordur, eastern Iceland, is correlated with the westward dipping exposed volcanic succession on the basis of extensive field mapping and paleomagnetic studies. The base of the landward extension of sea floor magnetic anomaly 5 (epoch 9) and other exposed marker formations can also be identified in the core. Field observations, inclu4ing vertically discontinuous dykes, the lack of lava-feeder relationships, and the measured K-Ar age difference between dykes and the surrounding lavas suggest that, contrary to previous in~erpretations, dykes of the Breiddalur dyke swarm were intruded by lateral injection from the south. These dykes are considerably younger than, and thus could not have fed, the exposed lava succession in the vicinity of the drill site. The lowest 450 m of the core may represent lavas related to activity in the Reydarfjordur volcanic center 13.5 km to the east. It is proposed that about 10.3 Ma the Reydarfjordur volcanic center ceased to be active and volcanic activity shifted about 20 km to the west, where the Breiddalur and Thingmuli volcanic centers later developed. The above field observations allow a model for the upper crustal construction of eastern Iceland to be proposed. The model assumes that the lava succession of eastern Iceland was formed. in at least three successive volcanic zones that resulted from frequent shifting of the location of greatest volcanism. Contrary to what is generally assumed, no systematic decrease in magnetic intensity with depth was observed for a 0.9 km thick vertical lava section in Holmatindur, about 13.5 km east of the drill site. This suggests that previous generalizations based on regional studies may have little predictive value when applied to certain specific areas.

Download or read book Volcanic and Igneous Plumbing Systems written by Steffi Burchardt and published by Elsevier. This book was released on 2018-05-09 with total page 356 pages. Available in PDF, EPUB and Kindle. Book excerpt: Volcanic and Igneous Plumbing Systems: Understanding Magma Transport, Storage, and Evolution in the Earth's Crust synthesizes research from various geoscience disciplines to examine volcanic and igneous plumbing systems (VIPS) in-depth. VIPS comprise a network of magma transport and storage features in the Earth’s crust. These features include dykes, sills and larger magma bodies that form the pathway and supply system of magma beneath active volcanoes. Combining basic principles with world-class research and informative illustrations, this unique reference presents a holistic view of each topic covered, including magma transport, magma chambers, tectonics and volcanism. Addressing a variety of approaches to these topics, this book offers researchers and academics in the Earth Science fields, such as geophysics, volcanology and igneous petrology the information they need to apply the information to their own disciplines. Provides an easily understandable overview of current research on volcanic and igneous plumbing systems Includes full color illustrations to increase understanding Covers fundamental information needed to optimize comprehension Features a field example from world-class research in each chapter, including photographs and maps
Download or read book Studies in Volcanology written by Thor Thordarson and published by Geological Society of London. This book was released on 2009 with total page 426 pages. Available in PDF, EPUB and Kindle. Book excerpt: Professor George Patrick Leonard Walker was one of the fathers of modern quantitative volcanology and arguably the foremost volcanologist of the twentieth century. In his long career, George studied a wide spectrum of volcanological problems and in doing so influenced almost every branch of the field. This volume, which honours his memory and his contributions to the field of volcanology, contains a collection of papers inspired by, and building upon, many of the ideas previously developed by George. Many of the contributors either directly studied under and worked with George, or were profoundly influenced by his ideas. The topics broadly fall under the three themes of lava flows and effusion, explosive volcanism, and volcanoes and their infrastructure.
Download or read book Modeling Volcanic Processes written by Sarah A. Fagents and published by Cambridge University Press. This book was released on 2021-02-11 with total page 902 pages. Available in PDF, EPUB and Kindle. Book excerpt: Understanding the physical behavior of volcanoes is key to mitigating the hazards active volcanoes pose to the ever-increasing populations living nearby. The processes involved in volcanic eruptions are driven by a series of interlinked physical phenomena, and to fully understand these, volcanologists must employ various physics subdisciplines. This book provides the first advanced-level, one-stop resource examining the physics of volcanic behavior and reviewing the state-of-the-art in modeling volcanic processes. Each chapter begins by explaining simple modeling formulations and progresses to present cutting-edge research illustrated by case studies. Individual chapters cover subsurface magmatic processes through to eruption in various environments and conclude with the application of modeling to understanding the other volcanic planets of our Solar System. Providing an accessible and practical text for graduate students of physical volcanology, this book is also an important resource for researchers and professionals in the fields of volcanology, geophysics, geochemistry, petrology and natural hazards.
Download or read book Evolution of an Andean Margin written by Suzanne Mahlburg Kay and published by Geological Society of America. This book was released on 2006-01-01 with total page 372 pages. Available in PDF, EPUB and Kindle. Book excerpt: "The objective of this volume is to examine the Cenozoic tectonic and magmatic evolution from the arc to the retroarc of a distinctive end-member of the Andean accretionary orogen between 35*S and 39*S. The evolution of the Andes in this region provides an outstanding case study of an orogen where periods of contraction and extension, crustal shortening and normal faulting, and differences in retroarc volcanism reflect a tectonic regime that alternates in space and time. Structural, magmatic, and paleogeographic patterns correlate strongly with the dynamics of the subduction zone. The region includes the Neuquen basin which is one of the most prolific of the Central Andes. The tectonic setting is important in understanding hydrocarbon systems of the sub-Andean basin and the potential for ore deposits in the cordillera. The book is fundamental for researchers working on tectonics and magmatism in Andean type systems as well as those involved in exploration."--Publisher's website.
