Available in PDF, EPUB and Kindle. Book excerpt: Rapakivi Granites and Related Rocks tells the story of Rapakivi granites, which are a group of granitic rocks characterized by specific texture (presence of plagioclase-mantled ovoidal to subhedral alkali feldspar megacrysts, two generations of quartz and feldspars) and A-type geochemical composition. Well-known representatives are the Proterozoic rapakivi granites that are found as anorogenic or post-orogenic batholith- to stock-sized intrusive complexes in the Precambrian cratons of Ukraine, Fennoscandia, South Greenland, Canada, United States, Brazil, Venezuela, and Siberia. The current knowledge of the rapakivi granites is largely based on the achievements of three International Geological Correlation Programme projects: IGCP-315 (Rapakivi Granites and Related Rocks) in in 1991-1996, IGCP-426 (Granite Systems and Proterozoic Lithospheric Processes) in 1998-2002, and IGCP-510 (A-type Granites and Related Rocks Through Time) in 2005-2009. After these projects, the research has continued actively utilizing enhanced geochemical methods, in situ geochemistry in particular. Rapakivi Granites and Related Rocks includes this research as well as abundant new geochemical and isotopic data combined with deeper understanding of geotectonic processes now allow more detailed tectonic and petrological modelling of the rapakivi granite magmatism and associated ore mineralization.

Book excerpt: This special volume stems from a symposium 'Granitic Systems - State of the Art and Future Avenues' that was held at the Department of Geology, University of Helsinki to mark the retirement of Professor Ilmari Haapala. The twenty articles in the volume cover a wide range of granite-related topics and focus on three general themes: tectonics and source regions, petrologic processes, and fractionated granites and pegmatites. Both original papers and reviews are included, and the volume will be acknowledged by anyone with a background in Earth Sciences ad a flavor for granitoid rocks. * Comprehensive account of the current status of granite-oriented research * Topics ranging from mineralogy, petrology, and geochemistry to tectonics and crustal evolution

Download or read book Proterozoic Crustal Evolution written by K.C. Condie and published by Elsevier. This book was released on 1993-02-03 with total page 553 pages. Available in PDF, EPUB and Kindle. Book excerpt: As a final product of the International Geological Correlation Program (IGCP) Project 217, this volume brings together significant advances in the understanding of Proterozoic crustal evolution. This IGCP Project focussed on nine research objectives: 1) Comparison of Archean and Proterozoic supracrustal assemblages to more fully understand differences between Archean and post-Archean tectonic regimes; 2) To more fully understand the geochemical differences between Archean and post-Archean sediments and to evaluate the various factors that control sediment composition; 3) From combined U/Pb zircon and whole-rock Sm/Nd studies, to see if the apparent 2.4-2.0 continental crust "generation gap" is real; 4) To employ new techniques in the dating of individual zircons to more fully understand Proterozoic tectonic history and the role of crustal reworking; 5) From trace element ratios and Nd isotopic data from basalts, to better understand Proterozoic mantle evolution; 6) To encourage more detailed studies of the anorogenic granite-anorthosite association to better understand its origin and significance in terms of crustal evolution; 7) From combined Nd, Pb, and Sr isotopic data, to more precisely estimate the amount of new continental crust formed during the Proterozoic; 8) To encourage joint P-T and geochronological studies of Proterozoic and high-grade terranes to better understand Proterozoic orogenesis: and 9) To try and understand why hydrothermal precious metal deposits are relatively rare in the Proterozoic compared to both the Archean and the Phanerozoic. The book should be of interest to professionals in the geosciences (especially geochemists, petrologists and structural geologists) and graduate students in the same fields.

Book excerpt: Dyke swarms are remnants of large igneous provinces, and are pointers of continental break-up events, as well as indicators for ancient continental reconstructions. These global geodynamic aspects are of crucial significance in tectonics, and with recent developments in high-precision age, dating it has become possible to enter these short-lived ma

Download or read book Anorthosites written by Lewis D. Ashwal and published by Springer Science & Business Media. This book was released on 2013-03-12 with total page 438 pages. Available in PDF, EPUB and Kindle. Book excerpt: The idea for a book on anorthosites came to me in January of 1986 while returning to Houston after holiday festivities in Dallas. The original idea was a review paper on anorthosites, but by the time I reached Houston, the subject material I contemplated induding was obviously too extensive for a single paper. The Director of the Lunar and Planetary Institute, Kevin Burke, was receptive to the idea of a book, and suggested that I contact Peter Wyllie, who serves as Editor of the Springer-Verlag series Minerals and Rocks. This effort, which I originally expected would take about a year, has taken nearly 6. I have many excuses- indolence, moving to another continent, other commitments, etc.-but the basic truth is that writing a book is much larger an undertaking than can be anticipated. Many people are aware of this, and I was duly forewarned. . But why write a book on anorthosites? This is a very good question, which I have considered from many angles. One rationale can be expressed in terms of a comparison between anorthosite and basalt. A first-order understanding of basalt genesis has been extant for many years. By contrast, there is little agreement about the origin of anorthosite. There are good reasons for studying and writing about basalt: it is the most abundant rock type on the Earth's surface, and is also plentiful on the surfaces of the other terrestrial planets.

Download or read book Sweden written by M. B. Stephens and published by Geological Society of London. This book was released on 2020-01-02 with total page 623 pages. Available in PDF, EPUB and Kindle. Book excerpt: The solid rock mass of Sweden forms a natural field laboratory revealing insight into the westward growth and reworking of one of the planet’s ancient continental nuclei. Three major geological units are exposed in different parts of the country: the western part of the Fennoscandian Shield, mainly sedimentary rocks deposited on this crystalline rock mass and the Caledonide orogen. This volume synthesizes the tectonic evolution of Sweden over more than 2500 million years from the Neoarchean to the Neogene. Following an introduction describing the lithotectonic framework of the country and the organization of the volume, the tectonic evolution is addressed essentially chronologically. Different phases of intracratonic rifting, accretionary orogeny, continent-continent collisional orogeny and platformal sedimentation are identified. Sweden is one of Europe’s major suppliers of metals, and the country’s mineral resources are also presented in the context of the lithotectonic framework. Sweden: Lithotectonic Framework, Tectonic Evolution and Mineral Resources has been designed to interest a professional geoscientific audience and advanced students of Earth Sciences.
