Download or read book Amazonia: Landscape and Species Evolution written by Carina Hoorn and published by John Wiley & Sons. This book was released on 2011-09-26 with total page 869 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book focuses on geological history as the critical factor in determining the present biodiversity and landscapes of Amazonia. The different driving mechanisms for landscape evolution are explored by reviewing the history of the Amazonian Craton, the associated sedimentary basins, and the role of mountain uplift and climate change. This book provdes an insight into the Meso- and Cenozoic record of Amazonia that was characterized by fluvial and long-lived lake systems and a highly diverse flora and fauna. This fauna includes giants such as the ca. 12 m long caiman Purussaurus, but also a varied fish fauna and fragile molluscs, whilst fossil pollen and spores form relics of ancestral swamps and rainforests. Finally, a review the molecular datasets of the modern Amazonian rainforest and aquatic ecosystem, discussing the possible relations between the origin of Amazonian species diversity and the palaeogeographic, palaeoclimatic and palaeoenvironmental evolution of northern South America. The multidisciplinary approach in evaluating the history of Amazonia has resulted in a comprehensive volume that provides novel insights into the evolution of this region.

Available in PDF, EPUB and Kindle. Book excerpt: Continuing the tradition of International Dyke Conference, this book is largely based on contributions from the IDC7 but also includes some chapters by invitation. It focuses on mafic dyke swarms and related associations: e.g. links with sills, kimberlites, syenites, carbonatites, and volcanics, discussing the following themes: (i) regional maps/reviews of dyke swarms and related units, (ii) the role of giant dyke swarms in the reconstruction of supercontinents/paleocontinents, (iii) mapping of dykes using remote sensing techniques, (iv) geochronology of dyke swarms, (v) petrology, geochemistry and petrogenesis of dykes, (vi) emplacement mechanism of dykes, (vii) dyke swarms and planetary bodies, and (viii) links to mineralization and resources.

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 1010 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.

Download or read book Large Igneous Provinces and their Plumbing Systems written by R. K. Srivastava and published by Geological Society of London. This book was released on 2022-03-15 with total page 598 pages. Available in PDF, EPUB and Kindle. Book excerpt: Identification of large-volume, short-duration mafic magmatic events of intraplate affinity in both continental and oceanic settings on the Earth and other planets provides invaluable clues for understanding several vital geological issues of current concern. Of particular importance is understanding the assembly and dispersal of supercontinents through Earth’s history, dramatic climate change events including mass extinctions, and processes that have produced a wide range of large igneous province (LIP)-related resources, such as Ni–Cu–PGE, Au, U, base metals and petroleum. This volume comprises 21 contributions on the latest developments and new information on LIPs and their plumbing systems and presents methodical studies on different components of LIP plumbing systems. These articles are especially helpful in understanding continental break-up events, regional domal uplift and a variety of metallogenic systems, as well as the temporal and spatial distribution of LIPs, their origin and their likely links to mantle plumes/superplumes.

Download or read book Cratonic Basin Formation written by M. C. Daly and published by Geological Society of London. This book was released on 2018-12-03 with total page 373 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cratonic basins are large, distinctive features of the continental crust. They are preferentially developed on thick continental lithosphere, are typically sub-circular in shape and subside over periods of hundreds of millions of years. They are also endowed with significant resources. However, in spite of their location in continental interiors and often well-known geology, the subsidence driving mechanism and tectonic setting of these basins remains controversial. This volume presents both lithospheric and basin scale datasets acquired specifically to interrogate the tectonic process of cratonic basin formation. Focused on the Silurian to Triassic Parnaíba cratonic basin of Brazil, the papers discuss the results of a multidisciplinary basin analysis project comprising new geophysical, geological and geochemical data. This unique dataset enables the characterization of the lithospheric crust and mantle beneath the Parnaíba Basin, constrains the detailed evolution of the basin itself, and enables comparisons with cratonic basins globally. Several convergent themes emerge providing new and powerful constraints for models of the driving mechanisms of these enigmatic basins.

Download or read book Optically Stimulated Luminescence (OSL) Dating in the Amazonian Wetlands written by Sonia Hatsue Tatumi and published by Cambridge Scholars Publishing. This book was released on 2020-07-09 with total page 146 pages. Available in PDF, EPUB and Kindle. Book excerpt: Optically stimulated luminescence (OSL) dating has proven to be extremely useful for establishing the Late Quaternary chronological framework in many areas of the Brazilian territory. In this region dominated by tropical climate, OSL dating can be more extensively applied than radiocarbon dating due to the generally low potential for the preservation of organic matter in sedimentary samples. This problem is especially critical in areas of the Amazonian lowlands, because of the hot climate and high precipitation rates. The abundance of quartz grains deposited in fluvial and aeolian environments over this region favours OSL dating. More than 20 years of continuous and collaborative work has resulted in the creation of an extensive OSL age database for Late Quaternary sedimentary deposits in the Amazonian lowlands. This effort has contributed to improving the paleoenvironmental and paleoclimatic reconstructions of this region within this period. This book discusses the state of art of OSL dating of Late Quaternary deposits in the Amazonian lowlands, focusing on providing an introduction to dating principles using OSL, and defining the application of OSL techniques as a dating method. It also offers a statistical study and calculation of equivalent dose and annual dose rates, details the sampling and experimental apparatus, and considers the difficulties and adaptation techniques in dating Late Quaternary strata in the Amazonian lowlands.
