Download or read book The Geology of the Guiana Shield written by Allan K. Gibbs and published by Oxford University Press, USA. This book was released on 1993 with total page 266 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Guiana Shield is an area of special importance, especially to those concerned with Precambrian geology because it provides a perspective on a part of Earth history not well represented elsewhere. For economic geologists, its mineral resource potential is just beginning to be understood. This overview of current knowledge will greatly help geologists already working in the area, draw attention to the need for mineral exploration research, and encourage the inclusion of the Shield in future Precambrian studies.

Book Synopsis Geology and Tectonics of Northwestern South America by : Fabio Cediel
Download or read book Geology and Tectonics of Northwestern South America written by Fabio Cediel and published by Springer. This book was released on 2018-08-10 with total page 1001 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides a comprehensive overview of the geological evolution of the Northern Andes and contiguous shield areas, with a focus upon Colombia. Updated geological interpretations are supported by modern lithogeochemical, seismic, gravity and magnetic data and radiogenic isotope and radiometric age determinations. The composite data permits a detailed interpretation of the tectono-magmatic history of the Northern Andean Block, including the Andes of Colombia, northern Ecuador, western Venezuela and eastern Panamá. Tectonic reconstructions based upon characterization of more than thirty litho-tectonic and morpho-structural units, terrane assemblages and tectonic realms, and their bounding suture and fault systems, highlight the intimate and complementary Mesozoic-Cenozoic history of the Northern Andean Block and the Pacific and Caribbean Plates. The complex nature of Northern Andean assembly contrasts with ‘‘classical’’ Central Andean ‘‘Cordilleran-type’’ orogenic models. Differences render the application of typical Cordilleran-type models inappropriate for the Colombian Andes. The importance of underlying Proterozoic through mid-Mesozoic elements, in the development of Meso-Cenozoic Northern Andean orogeny-phase tectonic configurations is analyzed in the light of spatial-temporal studies and reconstructions related to basin formation, sedimentation, deformation, uplift mechanisms, structural style and magmatic evolution. The pre-Andean architecture of north western South America has played a pre-determinative role in the development of the Northern Andean orogenic system. 16 contributions analyze key stratigraphic, structural, metamorphic, magmatic and tectonic questions, and provide solutions as far as the most recent published field-based studies permit. The volume provides geological interpretations and tectonic models which contrast with repetitive theoretical proposals frequently found in the available literature.

This book was released on 2015-01-23 with total page 554 pages. Available in PDF, EPUB and Kindle. Book excerpt: This work intent to give an introduction to the basic principles and concepts of geology for all those are interested in the understanding and learn about all the processes and phenomena that formed and shaped the Earth, since its formation, around 4,800 million years before present (BP). Early geologists, makes its task of studying and interpreting these processes, contributed to display the history of the planet and the origin of the life. Their work were the basis for future generations of scientists deepened and made new discoveries that contributed in the understanding of our planet and give a new view about its formation. Thanks to all these discoveries, geologists were able to put all the pieces together and understand all the processes that contributed to the formation of the South American continent that began in the first moments of the formation of the Earth’s crust 3,800 million years BP. This book, compile the geological history of the continent into a single text, while pointing out new aspects that were not covered at first.

Book Synopsis Historical Biogeography of Neotropical Freshwater Fishes by : James S. Albert
Download or read book Historical Biogeography of Neotropical Freshwater Fishes written by James S. Albert and published by Univ of California Press. This book was released on 2011-03-08 with total page 406 pages. Available in PDF, EPUB and Kindle. Book excerpt: The fish faunas of continental South and Central America constitute one of the greatest concentrations of aquatic diversity on Earth, consisting of about 10 percent of all living vertebrate species. Historical Biogeography of Neotropical Freshwater Fishes explores the evolutionary origins of this unique ecosystem. The chapters address central themes in the study of tropical biodiversity: why is the Amazon basin home to so many distinct evolutionary lineages? What roles do ecological specialization, speciation, and extinction play in the formation of regional assemblages? How do dispersal barriers contribute to isolation and diversification? Focusing on whole faunas rather than individual taxonomic groups, this volume shows that the area’s high regional diversity is not the result of recent diversification in lowland tropical rainforests. Rather, it is the product of species accumulating over tens of millions of years and across a continental arena.
Book Synopsis Suriname Revisited: Economic Potential of its Mineral Resources by : Marco Keersemaker
Download or read book Suriname Revisited: Economic Potential of its Mineral Resources written by Marco Keersemaker and published by Springer. This book was released on 2020-01-29 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book summarizes the exploration history and provides a framework for assessing the economic potential of the country’s minerals by defining minimal deposit parameters for the various commodities present. Suriname was explored extensively for mineral occurrences in the course of the previous century, indicating the presence of a range of commodities. The country mined and processed bauxite for a century (until 2016), and has an even longer history of small-scale alluvial gold mining; it is currently home to two major gold producers. However, exploration activities have been limited during the past 4 decades as most parts of Suriname’s interior are difficult to access, making geological fieldwork both difficult and expensive. Further, the markets and prices have changed in the interim, which calls for a fresh look at the historic data.

Book Synopsis Physiographic Sections of the Guiana Highlands, Venezuela and Guyana by : Charles Leroy Smith
Download or read book Physiographic Sections of the Guiana Highlands, Venezuela and Guyana written by Charles Leroy Smith and published by . This book was released on 1976 with total page 57 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report discusses the nature of the Guiana Shield and delimits meaningful subdivisions. The Shield contains the Guiana Lowlands, Guiana Hills, and Guiana Highlands, all physiographic provinces. To subdivide the Guiana Highlands into smaller units the geology, geomorphic features, soils, and vegetation were analyzed. This is in contrast with earlier studies which used river basins as physiographic sections. The analysis resulted in the formulation of three physiographic sections, the Sierra de Imataca, the Tepui Section, and the Western Highlands Section.

Book Synopsis Guyana: From Slavery to the Present by : Ramesh Gampat
Download or read book Guyana: From Slavery to the Present written by Ramesh Gampat and published by Xlibris Corporation. This book was released on 2015-04-15 with total page 618 pages. Available in PDF, EPUB and Kindle. Book excerpt: It is common knowledge that slavery and indenture were characterized by long hours of physical labor, restriction of movement and other basic human freedoms, and severe punishment for violations of draconian labor laws. Less well known is the fact that nutrition was very deficient and a range of infectious diseases maimed, debilitated and killed on a large scale. In trying to narrow the knowledge gap with respect to Guyana, Ramesh Gampat shows that extremely poor sanitary conditions, awful hygiene and malnutrition hastened widespread infections and created a vicious cycle. The British protected its own soldiers, officials and colonists by establishing a medical enclave that lasted until Emancipation in 1838. Former slaves were then “quarantined” to neglected and decaying villages and Indians to plantations. Concern with health conditions appeared only during periods of epidemics and even then it was essentially for the protection of Europeans. Colonial medicine opened the way for stereotyping, labeling, racialization of disease, neutralization of potential leaders in the struggle for justice, and crystallization of the view that Europeans were superior to Blacks and Indians. Shorter stature and shorter life expectancy are good indications that slaves and indentured immigrants fared considerably less well than Europeans. Several infectious diseases sickened and fell Blacks and Indians, including malaria and undefined fevers, pneumonia and bronchitis, diarrhea and enteritis, tuberculosis, pneumonia and hookworm. The conquest of malaria in the early 1950s accelerated the epidemiological transition from communicable to chronic noncommunicable diseases, and today NCDs account for some three-quarters of all deaths in Guyana. Malaria has reemerged, fueled by a gold boom that consumes huge amounts of mercury. The potentially adverse public health consequences of this relatively new dynamic, the combined trio, have been neglected.
