Available in PDF, EPUB and Kindle. Book excerpt: Basalt is the most voluminous of all the igneous rocks. Extensive field, experimental, petrographic and geochemical studies of basalt have provided us with a considerable understanding of igneous petrogenesis, plate tectonics, and crust-mantle interaction and exchange. One important aspect of geology that has developed over the last few decades is the study of oceanic basalts. The ocean basins cover about two thirds of the earth's surface and are floored by a basement of oceanic basalt that is continuously undergoing generation at spreading centres and destruction at subduction zones, a process which throughout geological time is recognized as the principal means of generating new crust. The study of oceanic basalts enables us to understand better the generation and recycling of crustal materials (including the continental crust), and the exchange between oceanic crust and seawater via hydrothermal activity. Compositional variations displayed by oceanic basalts provide windows into the mantle, and the identification of isotopically-distinct mantle reservoirs demonstrates that the source of oceanic basalts is heterogeneous and is controlled by convection and reservoir interactions within the mantle.

Download or read book The Geology of Continental Margins written by C.A. Burk and published by Springer. This book was released on 2013-12-20 with total page 976 pages. Available in PDF, EPUB and Kindle. Book excerpt: The continental margins of the world constitute the most impressive and largest physiographic feature of the earth's surface, and one of fundamentally great geological significance. Continental margins have been the subject of increasing attention in recent years, an interest focused by a body of new data that has provided new insights into their character. This interest was further stimulated by the realization that, in addition to the abundant living resources, continental margins contain petroleum and mineral resources that are accessible with existing technology. This realization, along with their basic geological importance, has provoked further research into the nature of continental margins throughout the world. A summary of these findings, as related to both recent and ancient continental margins, is the subject of this book. At various times in the past we had been approached individually to prepare a basic reference to continental margins; we then proposed to do such a volume jointly. However, the stimulus for the present volume eventually arose from a Penrose Conference arranged through the Geological Society of America. This conference was attended by specialists of numerous disciplines and from throughout the world, many of whom insisted that such a volume would be both timely and useful. Consequently, we agreed to undertake the task of assembling this book, with the objectives of making it available as soon and as inexpensively as possible.

This book was released on 2012-12-06 with total page 962 pages. Available in PDF, EPUB and Kindle. Book excerpt: J. L. Gressitt New Guinea is a fantastic island, unique and fascinating. It is an area of incredible variety of geomorphology, biota, peoples, languages, history, tradi tions and cultures. Diversity is its prime characteristic, whatever the subject of interest. To a biogeographer it is tantalizing, as well as confusing or frustrating when trying to determine the history of its biota. To an ecologist, and to all biologists, it is a happy hunting ground of endless surprises and unanswered questions. To a conservationist it is like a dream come true, a "flash-back" of a few centuries, as well as a challenge for the future. New Guinea is so special that it is hard to compare it with other islands or tropical areas. It is something apart, with its very complicated history (chapters I: 2-4, II: 1-4, III: I, VI: I, 2). It is partly old but to a great extent very young, yet extremely rich and complex. It has biota of different sources - to such a degree that it is still disputed in this volume as to what Realm it belongs to: the Paleotropical or Notogaean (Australian); or what Region: Oriental, "Oceanic," Papuan or Australian. The terms Papuasian, Indo-Australian and Australasian also have been applied to the area.

Download or read book Ophiolites written by R. G. Coleman and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 292 pages. Available in PDF, EPUB and Kindle. Book excerpt: I was invited to write this book as part of the Minerals, Rocks and Organic Materials Series of Springer-Verlag by Professor Peter J. Wyllie in 1974. Ophiolites have preoccupied me ever since 1948 as a graduate student and up to the present time as part of my research with the U.S. Geological Survey. During this period ophiolite, an obscure European geological term, has attained an ever-increasing importance, is now used to include all fragments of ancient oceanic lithosphere incorporated into the orogenic zones of modern and ancient continental margins, and is a standard part of the plate tectonic paradigm. The purpose of this book is to provide a starting point for anyone interested in the background and state of knowledge concerning ophiolites (ancient oceanic lithosphere). Because ophiolites represent fragments of old oceanic crust their tectonic setting and age are extremely important in the reconstruction of ancient plate boundaries. Present day plate tectonic theories involve the generation and disposal of oceanic lithosphere, so that these ancient fragments of oceanic lithosphere can be used directly to reconstruct conditions within the ancient oceans. Since 1970, numerous meetings and conferences directly related to ophiolites have stimulated worldwide interest in the subject. As part of the International Correlation Program, the project "Ophiolites of Continents and Comparable Oceanic Rocks," was initiated by Dr. N. Bogdanov, Geological Institute, Moscow. This project has brought together an international group that has focused on the outstanding problems and is now producing a world map of ophiolite distribution.
