Available in PDF, EPUB and Kindle. Book excerpt: The geology of the island of Dominica, at the center of the Lesser Antilles island arc, has been subdivided into four stratigraphic divisions: Division 1 (upper Miocene) is dominated by mafic volcanism; Division 2 (upper Pliocene-lower Pleistocene) is characterized by the development of two large stratovolcanoes over a 2 million year period; Division 3 (lower to upper Pleistocene) represents a period of island-wide quiescence except at the north and south of the island where two new centers developed on the flanks of the older stratovolcanoes; and Division 4 (upper Pleistocene-Holocene) characterized by the formation of numerous Peléan centers throughout the island. Three of these centers also produced large-volume pumiceous deposits that resulted in the formation of two calderas (Morne Trois Pitons and Wotten Waven). During Division 1 and 2 time, basaltic magmas produced by partial melting of the mantle with only minor sediment input ponded at the crust-mantle boundary, where subsequent rise and fractionation generated distinct basic and intermediate suites. During Division 3 time, the mid-crustal magma chambers beneath the Division 2 stratovolcanoes became barriers to the rise of these basic magmas, thus generating the quiescent period. However, the continued rise of magma beneath Dominica resulted in the intrusion of numerous sills into the lower crust, eventually producing a "hot zone." Ultimately, intermediate magmas produced in this "hot zone" caused the renewed volcanism during Division 4 time that produced numerous centers dominated almost exclusively by andesites and dacites of such similar compositions that the different centers cannot be geochemically distinguished from each other. The amalgamation of individual magma chambers beneath these different centers appears to have produced a mid-crustal batholith, which resulted in the uplift of the island, the formation of a central half-graben, and the current island-wide distribution of volcanic-related phenomena.

This book was released on 2013-11-07 with total page 260 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Using results from geological mapping, detailed stratigraphy, mineral chemistry, and geochemistry, the authors have developed a model to explain characteristics of Dominica not seen on many island arcs worldwide. The model suggests that during the Pleistocene partial melting of the island-arc crust generated a single magma body of batholithic proportions beneath the island"--Provided by publisher.
Download or read book Landscapes and Landforms of the Lesser Antilles written by Casey D. Allen and published by Springer. This book was released on 2017-07-19 with total page 326 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book focuses on the highly touristed, but surprisingly under-researched Lesser Antilles region. After offering a brief overview of the region’s geologic and tectonic history, as well as its basic climatology, subsequent chapters then discuss each island’s (or island set’s) geomorphology and geology, and how the settlement history, tourism, and hazards have affected their individual landscapes. Written by regional experts and replete with up-to-date information, stunning color imagery, and beautiful cartography (maps), it is the only comprehensive, scientific evaluation of the Lesser Antilles, and serves as the region’s definitive reference resource. Accessible to non-experts and amateur explorers, the book includes in-depth discussions and reference sections for each island/island set. Usable as both a textbook and guidebook, it offers readers a straightforward yet detailed assessment of an interesting and intriguing – but often-overlooked and under-appreciated – locale.

Download or read book Road from Geochemistry to Geochemometrics written by Surendra P. Verma and published by Springer. This book was released on 2019-08-16 with total page 675 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book highlights major problems in the statistical analysis of compositions that have been known for over a century, as well as the corresponding solutions that have been put forward by specialists over the past 30 years. The basic assumptions of normality or multi-normality are pointed out and methods to test and achieve them are also covered. The conventional major and trace element geochemistry and modeling equations are discussed, and are followed by a more sophisticated multidimensional approach to data handling. The book’s main focus is on the use of statistical techniques to facilitate data interpretation. It also highlights the classification (or nomenclature) and tectonic discrimination aspects for both igneous and sedimentary rocks. The book concludes by discussing computer programs that are helping pave the way from geochemistry to geochemometrics. Written by a leading expert in the area of geochemistry, it offers a valuable guide for students and professionals in the area.
Download or read book Encyclopedia of Islands written by Rosemary G. Gillespie and published by Univ of California Press. This book was released on 2009-08-19 with total page 1110 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Islands have captured the imagination of scientists and the public for centuries - unique and rare environments, their isolation makes them natural laboratories for ecology and evolution. This authoritative, alphabetically arranged reference, featuring more than 200 succinct articles by leading scientists from around the world, provides broad coverage of all the island sciences. But what exactly is an island? The volume editors define it here as any discrete habitat isolated from other habitats by inhospitable surroundings. The Encyclopedia of Islands examines many such insular settings - oceanic and continental islands as well as places such as caves, mountaintops, and whale falls at the bottom of the ocean. This essential, one-stop resource, extensively illustrated with color photographs, clear maps, and graphics will introduce island science to a wide audience and spur further research on some of the planet's most fascinating habitats." --Book Jacket.

Download or read book Earth s Landscape 2 volumes written by Joyce A. Quinn and published by Bloomsbury Publishing USA. This book was released on 2015-02-03 with total page 1211 pages. Available in PDF, EPUB and Kindle. Book excerpt: This unusual encyclopedia brings together in-depth information on more than 450 natural geographic features from around the world and offers an array of creative tools to promote critical thinking and classroom discussion. With Earth undergoing rapid environmental change, students and the general public alike should be knowledgeable about the world's geographic features. This authoritative, two-volume reference enables readers do just that. It describes continents and oceans; individual mountains, islands, caves, and rivers; and ecological entities such as wildlife refuges and national parks. Each entry provides a geographic overview of the feature's significance, location, description, geologic history, biota, protected areas, and environmental issues. But the coverage goes even deeper so that entries also discuss the cultural importance of each natural place, covering everything from indigenous beliefs to traditional folklore to contemporary legends. The encyclopedia stands apart from other works not only in the depth of its coverage but also in its range. It discusses lesser known as well as prominent geographical features and offers critical thinking aids that will help students see how the natural world relates to their daily lives. Teaching and learning tools include an appendix called "Opposing Viewpoints" that allows students to understand landforms involved in current conflicts and disputes as well as an "Activities/Discussion Questions" appendix.
