This book was released on 2018-09-25 with total page 116 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book studies the Fuegian Andes in Argentina, showing both simple and complex aspects. The first ones refer to the general stratigraphy of the area and the latter result from their tectonic characteristics. Concerning the stratigraphy, an appraisal of the denomination and valorization of formations of Jurassic and early Cretaceous age is performed here to reach the simple scheme of the Fuegian-Patagonian continuity under the name of “Fuegian Andes Deformed Complex”. As an essay the formational nomenclature is simplified and the local concept of basement is evaluated. In relation to their structural aspects it is assumed that the formation of the orogenic Fuegian arc and the folding of the Mesozoic and early Tertiary layers are connected phenomena. Tectonic forces from the West, the Northeast and the South have had participation in the formation of the tectonic arc. The lithostatic column pressure was added once the layers were folded and thrusted upwards during the birth of the Fuegian Andes. Even the speculation of a great main fold overturned to North, as an abstraction, is considered. Instead, the Magallanes-Fagnano fault is appreciated only as a product of the transcurrent Quaternary movements, lacking associated eruptive processes that contribute to define plate borders.
Download or read book Geodynamic Evolution of the Southernmost Andes written by Matías C. Ghiglione and published by Springer. This book was released on 2016-07-07 with total page 214 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book focuses on the strong relation between the tectonic evolution of the Southernmost Andes and their closest southern neighbors, the Scotia Sea and Antarctica. Some episodes are related to processes of global significance such as the opening of the Drake Passage, which is somehow linked to Late Cenozoic cooling. Many of the topics covered in the book are subjects of heated debates; as such, not only the latest data and approaches are presented, but different points of view as well. The chapters examine the interrelation between main geodynamic processes and plate tectonics from a multidisciplinary perspective. This Paleozoic-Cenozoic geodynamic evolution of the Southernmost Andes involved interrelated metamorphic, magmatic, sedimentary, and deformational processes directed by plate tectonics. The main topics cover the evolution of the Rocas Verdes basin and the Cordillera Darwin high-grade metamorphic complex, growth of the Patagonian Batholith, development of the Patagonian Orocline, the opening of the Drake Passage during growth of the Scotia Sea, evolution of the Austral-Magallanes foreland basin and its related fold and thrust belt.
Download or read book Growth of the Southern Andes written by Andrés Folguera and published by Springer. This book was released on 2015-11-27 with total page 281 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents recent findings on the structure and evolution of the Southern Andes. Through a detailed description of a series of orogenic segments reviewed by the different groups that have worked with structural and geophysical tools in each area over the last several years, it illustrates the diversity of mechanisms that have impacted strong orogenic gradients and consequently mountain morphology, from the southern Pampean flat subduction zone to the southern tip of the continent (33-56o S). The book also revises our conventional understanding of the source of the different Mesozoic to Cenozoic sections exhumed in the orogenic wedge, with the objective of discussing basin mechanisms through time. A final chapter discusses probable orogenic controls that have acted together in order to explain structure, the different deformational stages and intra-orogenic extensional collapses that affected the fold and thrust belt over time.
Download or read book Geological Resources of Tierra del Fuego written by Rogelio Daniel Acevedo and published by Springer Nature. This book was released on 2021-02-13 with total page 372 pages. Available in PDF, EPUB and Kindle. Book excerpt: The CADIC’s Geological Resources Program will soon turn 40 years of fruitful development. During this period many projects were carried out and others remain to be implemented. In the course of time three generations of researchers have been formed. Mentioning names would be unfair to those that could be involuntarily omitted. There is still a long way to go. The eagerness for knowledge should not stop. This book is a tribute to all those people who have worked in the different projects of pure and applied science, and educational, and human resources training, granted to this founding program and associated laboratories of the regional center of CONICET in Ushuaia, Tierra del Fuego, Argentina. The twenty papers which constitute this book have a genuine Latin appeal, having been written by 50 authors based in Argentina and Spain. All this contributions are concerned with Fuegian geological resources. Everyone concerned with this work hopes that it will prove a fitting and lasting memorial to Nacho Subías, whose personal contribution to our knowledge of this geology was outstanding.

Download or read book Palaeomagnetism in Fold and Thrust Belts New Perspectives written by E.L. Pueyo and published by Geological Society of London. This book was released on 2016-08-23 with total page 289 pages. Available in PDF, EPUB and Kindle. Book excerpt: Palaeomagnetism is a technique used to understand complex deformation patterns in fold-and-thrust belts; it can be used to characterize the distribution, magnitude and timing of vertical axis rotations, an elusive variable using other methods. A combination of palaeomagnetic and structural geology analyses has helped to unravel the geometry and kinematics of fold-and-thrust belts around the world and of different geological ages for more than 50 years. This volume comprises three sections: the first shows thorough overviews of western Mediterranean arcs and the western Carpathians; the second depicts several examples from the Andes, the Alps, Anatolia, Pyrenees, Iberian Ranges and the Atlas; and the third shows the latest research on the use of palaeomagnetism to understand fold-and-thrust belts in 3D and 4D in a more quantitative way and it also includes some methodological proposals to avoid common errors. In the papers of the first two sections, the combination of palaeomagnetic analyses with structural data, AMS or magnetostratigraphic analyses demonstrate the usefulness of palaeomagnetism in deciphering complex deformation patterns in fold-and-thrust belts.

Download or read book Mineral Deposit Research Meeting the Global Challenge written by Jingwen Mao and published by Springer Science & Business Media. This book was released on 2008-01-08 with total page 1580 pages. Available in PDF, EPUB and Kindle. Book excerpt: In June 1965, a small group of European economic geologists gathered in Heidelberg, Germany, at the invitation of Professor G. C. Amstutz and decided to establish the Society for Geology Applied to Mineral Deposits (SGA) and to start a journal to be called Mineralium Deposita. The first issue of the journal came out in May 1966, and has now matured to a leading journal in economic geology The first Biennial SGA Meeting was held successfully in Nancy, France, in 1991, with subsequent meetings in Grenada (Spain; 1993), Prague (Czech Republic; 1995), Turku (Finland; 1997), London (United Kingdom; 1999), Krakov (Poland; 2001) and Athens (Greece; 2003). In 2002, th the SGA Council decided that its 8 Biennial Meeting in 2005 should be held in Beijing, China, making this the first Biennial Meeting to be convened outside - th rope. Significantly, 2005 also marks the 40 anniversary of the SGA. The decision to host this year’s premier meeting in Beijing reflects the Society’s successful transition from its traditional European focus to a truly global organization, with 24% of SGA members situated in North America, 13% in Australia and Oceania, and 5% in Asia. Over the last 27 years China has made dramatic progress towards political and economic reform, and opening the nation to the outside world. China’s rapid e- nomic development demands increasing amounts of minerals, fuels and materials, and this is currently a major driver for the global economic markets.

This book was released on 2012-10-11 with total page 381 pages. Available in PDF, EPUB and Kindle. Book excerpt: Coastal exposures of the Santa Cruz Formation in southern Patagonia have been a fertile ground for recovery of Early Miocene vertebrates for more than 100 years. This volume presents a comprehensive compilation of important mammalian groups which continue to thrive today. It includes the most recent fossil finds as well as important new interpretations based on ten years of fieldwork by the authors. A key focus is placed on the paleoclimate and paleoenvironment during the time of deposition in the Middle Miocene Climatic Optimum (MMCO) between twenty and fifteen million years ago. The authors present the first reconstruction of what climatic conditions were like and present important new evidence of the geochronological age, habits and community structures of fossil bird and mammal species. Academic researchers and graduate students in paleontology, paleobiology, paleoecology, stratigraphy, climatology and geochronology will find this a valuable source of information about this fascinating geological formation.
Download or read book Andean Structural Styles written by Gonzalo Zamora and published by Elsevier. This book was released on 2022-04-26 with total page 528 pages. Available in PDF, EPUB and Kindle. Book excerpt: Andean Structural Styles: A Seismic Atlas is a comprehensive reference illustrating the variability in structural styles and hydrocarbon traps that exist in the Andean chain. The Andean chain, stretching over more than 5,000 km (3,000 mi) from Venezuela to Argentina, contains a large number of sedimentary basins which have developed in a wide range of tectonic settings. Some of these basins are highly mature, with hydrocarbon production from Paleozoic, Mesozoic, and Cenozoic sedimentary sequences, while others are still underexplored. Andean Structural Styles: A Seismic Atlas covers topics including fold types, thrust faults, triangle zones, inversion structures, synorogenic deposits, and growth stratal geometries. These topics are illustrated by thirty-two seismic examples interpreted and uninterpreted, covering most of the Andean basins, and five chapters reviewing the structural styles of the Andes, the complexity of processing seismic in these settings, how analogue models help in the interpretation, and several outcrop analogues. This reference is invaluable to both hydrocarbon exploration of the Andes and researchers and students in the fields of exploration geology and structural geology. Also, those teaching structural geology and seismic interpretation will find a valuable resource with lots of uninterpreted seismic examples that can be used in their lectures. - Includes a vast collection of high-quality, color images - Features case studies covering the entirety of the Andes Mountain chain - Presents high-quality seismic data that was previously only available to oil companies

Download or read book Geology s Significant Sites and their Contributions to Geoheritage written by R. M. Clary and published by Geological Society of London. This book was released on 2024-07-23 with total page 471 pages. Available in PDF, EPUB and Kindle. Book excerpt: The contributions in this book explore several geologically significant sites and, in doing so, acknowledge and explore not just the geological exposures themselves, but also the people and issues that are fundamentally intertwined with the history of our science and its impact on our society. Through selective examples of outcrops and locales integral to the history of geology, we explore the evolution of modern geology, as well as the geodiversity and geoheritage of our planet. While the volume is far from comprehensive, the chapters contained herein detail a range for geoheritage value, scale of geoheritage sites and potential for geoheritage opportunities that will promote a broader, richer understanding of the complexity of the geoheritage of Earth. Importantly, many chapters offer a cautionary tale of sites almost lost to posterity and submit their take-away lessons for community mobilization towards geoheritage site protection.
