Download or read book Island Arcs written by A. Sugimura and published by Elsevier. This book was released on 2013-10-22 with total page 256 pages. Available in PDF, EPUB and Kindle. Book excerpt: Developments in Geotectonics, 3: Island Arcs: Japan and its Environs focuses on geophysical and geological characteristics of island arcs. The book first reviews the geophysical and geological features of island arcs, including topography, crust and upper mantle structure, seismicity, direction of principal stresses of earthquakes, crustal deformation and fault systems, and geological structure. The distributions of Cenozoic volcanoes and hot springs, petrology of volcanic rocks, magnetic fields, and anomaly of electrical conductivity are also discussed. The publication also takes a look at the Cenozoic history of the Japanese Islands relative to the formation of island arcs. The Quaternary tectonic movements of Japan are reviewed. The text ponders on the processes under island arcs, such as generation and ascent of primary magma; convection current descending under island arcs; island arc tectonics and oceanic ridge tectonics; and mechanical process inferred from seismic wave radiation. The text is a valuable reference for geologists and readers interested in island arcs.

Book excerpt: This volume contains a collection of papers presented as distinguished guest lectures at the International Conference on ``The Origin of Arcs'' held at the University of Urbino in September 1986, under the joint sponsorship of the European Union of Geosciences and the Italian Geological Society. The workshop on island and mountain arcs has been organized with the aim of increasing our understanding of the intrinsic nature of orogenic and post-orogenic processes, on the basis of empiric factual data, rather than particular theoretic models. Quite often a trivial piece of field data appears to bear much more weight than many fascinating hypotheses put forward by the human mind. This seems to be much more valid in geology, where a special method is necessitated by the particular nature of the geological phenomena and the time concept. Every general law deduced should be rooted in the study of the earth's development in geological time. It is the editor's opinion that there must first be an inductive picture by means of geological methods and then it must be interpreted by geophysicists in the light of physical laws. The geological method must serve, besides, to test the historical credibility of geophysical theories. It is clear that these two methods, the geological-historical one and the geophysical one, must be complementary and the one must not substitute the other. Since the problem of the structure and origin of arcs is open to several solutions, different factors being still unexplained, all correctly deduced opinions are considered by the editor. The contributors to this pre-conference volume have been asked to present essential geological results, as concrete as possible, on some basic problems, such as: Are the island and mountain arcs primary or induced features? How have these orogenic festoons developed into their similar regular shapes? What are the relationships between "primary" active arcs and "secondary" mountain arcs? What is the dominant deformational factor in the bulging of the arc? What is the real nature and tectonic significance of the Benioff zone? These papers have been grouped into five more or less natural sections, of which three are defined on the basis of geography. But of course several range broadly and the classification serves only to channel the discussion in a practical way.

Download or read book Oceanography written by Arnold L. Gordon and published by Elsevier. This book was released on 2013-10-22 with total page 227 pages. Available in PDF, EPUB and Kindle. Book excerpt: Annals of the International Geophysical Year, Volume 46: Oceanography covers the program of oceanographic studies conducted during the International Geophysical Year (IGY). The program includes long wave and sea level recording, deep water circulation, polar front survey, and multipleship current measurement. This book is composed of six chapters and begins with the objective and aims of the oceanographic program and the national contributions to this program. The succeeding chapters discuss the problem in delineating sea-level cycle and the results of the North Atlantic Polar Front Survey in the IGY. These topics are followed by a survey of the results from many oceanographical expeditions. Particularly good results were obtained during the IGY period by the use of special large-scale precision automatic recorders of the phototelegraph station type. The last chapter describes the artificial radioactivity in the oceans consisting mainly of fission products of U235, Pu239 and U238 from reactors and nuclear explosion devices. This book is of value to geophysicists, and marine scientists and researchers.

Book Synopsis Temper Sands in Prehistoric Oceanian Pottery by : William R. Dickinson
Download or read book Temper Sands in Prehistoric Oceanian Pottery written by William R. Dickinson and published by Geological Society of America. This book was released on 2006-01-01 with total page 176 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Oceanian ceramic cultures making earthenware pottery spread during the past 3500 years through a dozen major island groups spanning 6000 km of the tropical Pacific Ocean from western Micronesia to western Polynesia. Island potters mixed sand as temper into clay bodies during ceramic manufacture. The nature of island sands is governed by the geotectonics of hotspot chains, island arcs, subduction zones, backarc basins, and remnant arcs as well as by sedimentology. Because small islands with bedrock exposures of restricted character are virtual point sources of sand, many tempers are diagnostic of specific islands. Petrographic study of temper sands in thin section allows distinction between indigenous pottery and exotic pottery transported from elsewhere. Study of 2223 prehistoric Oceanian potsherds from 130 islands and island clusters indicates the nature of Oceanian temper types and documents 105 cases of interisland transport of ceramics over distances typically

In this regard, it discusses in detail the various genetic mineralization styles in the ANS including: (1) magmatic mineral deposits associated with mafic-ultramafic rocks (e.g. chromite, Ni-Cu-Co-PGE magmatic sulfides, Fe-Ti-V oxides), (2) intrusion-related (magmatic-hydrothermal) deposits associated with felsic to intermediate rocks (porphyry, epithermal Au-Ag/sulfide vein type family, skarn, granite-related pegmatite-REE deposits), (3) hydrothermal orogenic gold and volcanogenic massive sulfide (VMS) deposits, as well as (4) surficial mineral deposits (chemical-sedimentary, residual, mechanical and supergene enrichment deposits).
Book Synopsis Arc Volcano of Japan by : Takeru Yanagi
Download or read book Arc Volcano of Japan written by Takeru Yanagi and published by Springer. This book was released on 2011-07-07 with total page 132 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents an analysis of our current knowledge on the origin of the Earth’s continental crust. There are two aspects to consider: tectonic and igneous processes. Tectonic aspects include sedimentary accretion, terrane accretion, and continental collision at continental margins, in association with plate subduction. These processes result in the formation of large mountain belts, the building up of which literally grows the continents. However, these tectonic aspects are concerned with material recycling within the crust, and hence do not contribute to volumetric growth of continental crust. Igneous processes concern separation of continental crust from the mantle and result in the volumetric growth of continental crust. Therefore, the main focus of this book is to systematically examine why and how the Earth’s continental crust forms, by evaluating magmatic processes at island arcs where new continental crust forms.

This book was released on 2008-01-01 with total page 446 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Inspired by a GSA Penrose Conference held in 2005 (cosponsored by the International Association of Sedimentologists and the British Sedimentological Research Group), the 17 papers in this volume explore sedimentary environments in arc collision zones and their utility in recording the evolution of modern and ancient convergent margins. The first set of papers in the collection focuses on formation and evolution of the sedimentary record in arc settings and arc collision zones, concentrating on modern intra-oceanic examples. Papers include studies of flexural modeling and factors that affect development of siliciclastic and carbonate deposits around modern arcs. The second half of the volume presents new applications of arc sedimentary records. These relate primarily to constraining tectonic events in the evolution of arc systems, but also concern the links among tectonic uplift, collision, and geomorphic and climatic feedback mechanisms in arc collision zones."--Publisher's website.

Book Synopsis Essentials of Igneous and Metamorphic Petrology by : B. Ronald Frost
Download or read book Essentials of Igneous and Metamorphic Petrology written by B. Ronald Frost and published by Cambridge University Press. This book was released on 2013-11-11 with total page 321 pages. Available in PDF, EPUB and Kindle. Book excerpt: All geoscience students need to understand the origins, environments and basic processes that produce igneous and metamorphic rocks. This concise textbook, written specifically for one-semester undergraduate courses, provides students with the key information they need to understand these processes. Topics are organized around the types of rocks to expect in a given tectonic environment, rather than around rock classifications: this is much more interesting and engaging for students, as it applies petrology to real geologic environments. This textbook includes over 250 illustrations and photos, and is supplemented by additional color photomicrographs made freely available online. Application boxes throughout the text encourage students to consider how petrology connects to wider aspects of geology, including economic geology, geologic hazards and geophysics. End-of-chapter exercises allow students to apply the concepts they have learnt and practice interpreting petrologic data.
