Book excerpt: Magnatism is the only true endogenic process for generating new material on the Earth's surface. Obviously, magmatism and tectonic movements are reflections of geodynamics, that is, physical processes which occur in deep-seated environments. What are the interrelationships between magmatism and tectronics? How did the character of terrestrial magmatism change through time and are there any irregularities in this process?

Available in PDF, EPUB and Kindle. Book excerpt: This doctoral thesis applies measurements of ground deformation from satellite radar using their potential to play a key role in understanding volcanic and magmatic processes throughout the eruption cycle. However, making these measurements is often problematic, and the processes driving ground deformation are commonly poorly understood. These problems are approached in this thesis in the context of the Cascades Volcanic Arc. From a technical perspective, the thesis develops a new way of using regional-scale weather models to assess a priori the influence of atmospheric uncertainties on satellite measurements of volcano deformation, providing key parameters for volcano monitoring. Next, it presents detailed geodetic studies of two volcanoes in northern California: Medicine Lake Volcano and Lassen Volcanic Centre. Finally, the thesis combines geodetic constraints with petrological inputs to develop a thermal model of cooling magma intrusions. The novelty and range of topics covered in this thesis mean that it is a seminal work in volcanic and magmatic studies.
Download or read book Geological Geophysical and Petrochronological Constraints on the Interplay Between Magmatism and Deformation in Magmatic Arc Systems written by Sarah Frances Trevino (Ph.D.) and published by . This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Deformation and arc magmatism are two fundamental processes of tectonism. Deformation is expressed as fault systems and shear zones that evolve to accommodate plate motion and arc magmatism is expressed as voluminous intrusive suites. Major questions remain, however, as to the relationship between deformation and arc magmatism. My dissertation investigates plutons and shear zones using structural geologic, geophysical, and petrochronologic tools, to observe how they are expressed temporally and spatially to assess feedbacks between arc magmatism and deformation.Chapter one used gravity investigations to observe modern magma emplacement and storage at Laguna Del Maule. Laguna Del Maule is a volcanic field (LdMVF) within a modern magmatic arc, where rhyolitic volcanism is associated with strike-slip faults. Our new density model of the broader LdMVF captured what we interpret as at least two magma bodies at different stages of maturity. From these data, we concluded that multiple discrete plutons presently exist in the LdMVF. Chapters two, three, and four used structural and geochronological methods to investigate how pluton emplacement is connected to ductile shear zones by investigating exhumed examples of magmatic arcs emplaced during oblique convergence. Chapter two was a collaborative study with Dr. Claire Harrigan at Boise State University. Together we used petrochronology to investigate high-temperature crustal strain partitioning and localization on the micro- to macro-scale using the western Idaho shear zone (WISZ), west-central Idaho. By integrating the geochronometric, geochemical, and microstructural titanite record, we documented the local preservation of titanite related to magmatic and deformation processes. Importantly, our results provide a date for the onset of deformation in the WISZ, confirming tectonic interpretations of WISZ deformation as a separate event from terrane suturing. Chapter three and four expanded this work to the Cretaceous intrusive suites of Nevada in the central United States Cordillera. Chapter three is a first order investigation of middle and Late Cretaceous granodiorites of northwest Nevada. Chapter four expands on this original dataset to track the spatial-temporal patterns of pluton emplacement and deformation using fabrics preserved within the Sahwave Range intrusive suite and the Power Line intrusive complex. We determined that the Sahwave Range intrusive suite and Power Line intrusive complex record two distinct dextral transpressional deformation events, ~100 Ma and ~88 Ma, and provide a missing link between the Sierra Crest shear zone in the Sierra Nevada batholith and the western Idaho shear zone in the Idaho batholith.

Download or read book Snake River Plain Yellowstone Volcanic Province written by Kerry L. Ruebelmann and published by American Geophysical Union. This book was released on 1989 with total page 122 pages. Available in PDF, EPUB and Kindle. Book excerpt: Published by the American Geophysical Union as part of the Field Trip Guidebooks Series, Volume 305. This field trip was conceived as a way to introduce one of the major volcano-tectonic features of the North American continent to visiting scientists from abroad. Its objectives are to allow the participants to observe first hand the geologic relationships relevant to the formation of the Snake River Plain (SRP) and to discuss various interpretations of SRP genesis. The approach to these objectives is to travel the length of the plain from northeast to southwest and to examine in a logical manner, from younger to older volcanic rocks, the relationships important to an understanding of its origin and evolution (Fig. 1). Even though basaltic volcanism is commonly thought of in association with the SRP, this field trip will emphasize the importance of silicic volcanism because of its much greater volume and because of its profound effect on the upper crustal structure of the SRP.

This book was released on 2017-09-11 with total page 393 pages. Available in PDF, EPUB and Kindle. Book excerpt: Dedicated to Bob Hatcher, this Memoir explores linkages between tectonic processes through a series of field-, numerical- and laboratory-based studies, concentrating on feedback mechanisms within ancient and evolving orogens by which individual or linked tectonic processes may influence or predetermine the operation of other processes in space and time. Case studies cover a wide range of ancient to modern orogens: the Svecofennian of southern Finland, the Gyeonggi Massif of Korea, the Caledonides of northern Scotland, the Variscan of the East European craton, the Appalachians of the eastern United States, the European Alps and Dinarides, north Cascades of the northwestern United States, and the Himalaya. Emphasis is placed on integration between data sets developed from a wide range of analytical approaches, including: field mapping, seismic reflection profiling, strain analyses, petrology, isotopic dating, and numerical modeling-based studies of thermal evolution associated with tectonic processes such as thrust-related burial and exhumation.

Book excerpt: This is a discount Black and white version. Some images may be unclear, please see BCCampus website for the digital version.This book was born out of a 2014 meeting of earth science educators representing most of the universities and colleges in British Columbia, and nurtured by a widely shared frustration that many students are not thriving in courses because textbooks have become too expensive for them to buy. But the real inspiration comes from a fascination for the spectacular geology of western Canada and the many decades that the author spent exploring this region along with colleagues, students, family, and friends. My goal has been to provide an accessible and comprehensive guide to the important topics of geology, richly illustrated with examples from western Canada. Although this text is intended to complement a typical first-year course in physical geology, its contents could be applied to numerous other related courses.
