Download or read book Continent Formation Growth and Recycling written by Paul Joseph Sylvester and published by Elsevier Science Publishing Company. This book was released on 2000 with total page 218 pages. Available in PDF, EPUB and Kindle. Book excerpt: Debating the premises of Hurley and Rand versus those of Armstrong on the formation of continents, scientists gathered in a special session of the 1998 Annual Meeting of the Geological Society of America in Toronto in October to discuss "Continent Formation, Growth and Recycling". Twenty-four talks were presented, ten of which have been developed into papers published in this special issue of Tectonophysics . The papers are grouped by subdiscipline: Ogawa, de Smet et al., Schott et al., and Regenauer-Lieb and Yuen present numerical models of asthenospheric melting and convection and lithospheric break-up and delamination. Green et al., Krapez et al., and Henry et al. report geologic geochronologic, geochemical and isotopic data for some key Archean cratonic terranes. Condie, Abbott et al., and Vlaar discuss global models for crustal growth, emphasizing episodic magmatism, crustal and lithospheric thickness, and crustal isostasy, respectively. Readers of the entire special issue will see that a definitive answer to the overall question of continental growth rates has not been reached but that much progress is being made on understanding the processes involved in continent development.

Available in PDF, EPUB and Kindle. Book excerpt: The motivation for this volume came from the idea that thePrecambrian is the key, both to the present, and to theunderstanding of the Earth as a whole. The Precambrian constitutesabout 85% of Earth's history, and of that, about 3.75 billion yearsof Precambrian time, represented by rocks, are accessible togeoscientists. Ancient atmospheric and environmental conditions canbe traced back to the time when the Earth was only about 250million years old. Precambrian rocks supply almost 75% of importantmineral resources such as Fe, Mn, Au, Pt and Cr. Many of theseelements are associated with sedimentary rocks and some importanthydrocarbon, coal and graphite deposits are also hosted byPrecambrian rocks. This volume is aimed at geoscientists interested in Precambriansedimentary rocks and at students of Earth history. It containsreview articles discussing Precambrian conditions and case studiesfrom Precambrian shields and successions of North and SouthAmerica, Australia, Africa, Europe, Asia and India. Theintroductory papers, written by experts on Precambrianenvironments, treat comprehensively the application of actualism tothe Precambrian, the evolution and influence of life on thesedimentary rock record, the genesis of Banded Iron Formations, thePrecambrian sulphur cycle and the significance of Precambrianchemical carbonate precipitates. The case studies includedepositional settings and processes in Archean terranes, inPaleoproterozoic sequences, with some emphasis on the lack ofvegetation and weathering, and in late Proterozoic sequences, withsome emphasis on glacial deposits. The contributions demonstratethat Precambrian sedimentary deposits are commonly similar to theirPhanerozoic counterparts in terms of composition, sedimentaryprocesses, and depositional setting, but may differ significantlyas a result of lack of vegetation, climatic and biologicalconstraints, composition and circulation of seawater, and thesecular involvement of continental crust.
