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 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 Earths 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.

"AAPG Memoir 79, The Circum-Gulf of Mexico and the Caribbean, is the first volume in more than a decade to document such a wide range of research on the geology of this vast area. Of the total 44 papers, roughly two-thirds pertain to the Gulf of Mexico, with an emphasis on the Mexican portion of the basin, and to the petroliferous areas of the southern Caribbean, including Colombia, Venezuela, Cuba, and Trinidad and Tobago. The remaining papers relate to the Antilles and Central America, as well as a series of papers that address region-wide topics such as plate tectonic evolution. A significant number of papers were contributed by authors from national oil companies and universities from within the region." --AAPG.

This monograph reviews the nature of Quaternary environmental changes over the largest continent in the Southern Hemisphere. Moreover, since South America makes a transect across most climatic belts of an entire hemisphere, it provides a unique opportunity to examine the impact of changing Quaternary climates on a variety of environments. It also forms the basis for judging the synchrony or non-synchrony of Quaternary climatic changes between hemispheres and this has important implications for climatic modelling.As South America has a dynamic tectonic regime along its western margin, 3 chapters discuss the geomorphological impact of Quaternary tectonics and volcanism. The following 6 chapters integrate evidence for Quaternary changes in the great alluvial basins of the Continent Orinoco, Amazon, Paranaacute;) and in the contiguous highland massifs (Guyana, Brazil, Patagonia). As parts of the Andes have been high enough to support glaciers since the late Miocene, 5 chapters review the nature and consequences of Quaternary glacier fluctuations. The following 4 chapters select major process-form systems that impacted the continent during the Quaternary, including geocryogenic activity, palaeolake development, palaeo-gravel formations and coastal changes. Three chapters provide the first major review of Quaternary vegetation changes in South America (primarily the Andes) deduced from palaeoecological data. The final chapter weaves most of the environmental threads together in an overall synthesis of the Quaternary of South America.The book is lavishly illustrated with photographs and line diagrams. As it provides a compendium of data and analyses about Quaternary changes for a whole continent, this book should appeal to a wide range of environmental disciplines.

The 'sedimentary cover' refers to the stratified rocks of youngest Proterozoic and Phanerozoic age that rest upon the largely crystalline basement rocks of the continental interior. This volume presents data and interpretations of the geophysics of the craton and summarizes the craton's tectonic evolution. It also presents the stratigraphy, structural history, and economic geology of specific sedimentary basins (e.g. Appalachian basin) and regions (e.g. Rocky Mountains). It concludes with a discussion of the currently popular theories of cratonal tectonics, & unresolved questions are identified.

Advances in space-borne technologies lead to improvements in observations and have a notable impact on geodesy and its applications. As a consequence of these improvements in data accuracies, spatial and temporal resolutions, as well as the developments in the methodologies, more detailed analyses of the Earth and a deeper understanding of its state and dynamic processes are possible today. From this perspective, this book is a collection of the selected reviews and case-study articles that report the advances in methodology and applications in geodesy. The chapters in the book are mainly dedicated to the Earth’s gravity field theory and applications, sea level monitoring and analysis, navigation satellite systems data and applications, and monitoring networks for tectonic deformations. This collection is a current state analysis of the geodetic research in theory and applications in today’s modern world.
