Alluvial fan deposition in the Argentine Central Precordillera is part of a sediment routing system that changes along strike of an active thrust front. This study area is partitioned into erosional and depositional sectors for analysis. The erosional sector drainage basins are analyzed using topographic data from a digital elevation model, to see how morphology changes with fault displacement. Drainage basins become shorter with more displacement. The depositional sector alluvial fans are classified using spectral characteristics from satellite imagery. The fans are classified based on thermal, near infrared, and elevation parameters. Fans close to the thrust front are interpreted to be old sheetflood deposits, with younger fans more distal from the front in the foreland. In this setting, progressive fault displacement causes shortening of the erosional sector, increasing the efficiency of sediment evacuation from the range, and causing a progradation of sheetflood fans into the foreland basin. Remote sensing analysis techniques are useful for characterizing the sediment routing system of alluvial systems where field-based information (geodetic, seismic, structural and lithologic data) is not available.

Andean Tectonics addresses the geologic evolution of the Andes Mountains, the prime global example of subduction-related mountain building. The Andes Mountains form one of the most extensive orogenic belts on Earth, spanning approximately an 8,000-km distance along the western edge of South America, from ~10°N to ~55°S. The tectonic history of the Andes involves a rich record of diverse geological processes, including crustal deformation, magmatism, sedimentary basin evolution, and climatic interactions. This book addresses the range of Andean tectonic processes and their temporal and spatial variations. An improved understanding of these processes is fundamental not only to the Andes but also to other major orogenic systems associated with subduction of the oceanic lithosphere. Andean Tectonics is a critical resource for researchers interested in the causes and consequences of Andean-type orogenesis and the long-term evolution of fold-thrust belts, magmatic arcs, and forearc and foreland basins. Evaluates the history of Andean mountain building over the past 300 million years Integrates recent studies and new perspectives on the complementary records of deformation, magmatism, and sedimentary basin evolution and their interactions in time and space Provides insight into the development of the northern, central, and southern Andes, which have typically been considered in isolation

This Special Publication arises from the UNESCO-sponsored IGCP 586-Y project `The tectonics and geomorphology of the Andes (32°–34°S): interplay between short-term and long-term processes’. It includes state-of-the-art reviews and original articles from a multidisciplinary perspective that investigate the complex interactions of tectonics and surface processes in the subduction-related orogen of the Andes of central Chile and Argentina (c. 27° –39°S). It aims to improve our understanding of tectonic and landscape evolution of the Andean range at different time scales, as well as the mutual relationship between internal and external mechanisms in Cenozoic deformation, mountain building, topographic evolution, basin development and mega-landslides occurrence across the flat slab to normal subduction segments. The geodynamic processes of the Andes of central Chile and Argentina are analysed from a number of subdisciplines of the Earth sciences, including tectonics, petrology, geophysics, geochemistry, structural geology, geomorphology, engineering geology, stratigraphy and sedimentology.

Alluvial fans are important sedimentary environments. They trap sediment delivered from mountain source areas, and exert an important control on the delivery of sediment to downstream environments, to axial drainages and to sedimentary basins. They preserve a sensitive record of environmental change within the mountain source areas. Alluvial fan geomorphology and sedimentology reflect not only drainage basin size and geology, but change in response to tectonic, climatic and base-level controls. One of the challenges facing alluvial fan research is to resolve how these gross controls are reflected in alluvial fan dynamics and to apply the results of studies of modern fan processes and Quaternary fans to the understanding of sedimentary sequences in the rock record. This volume includes papers based on up-to-date research, and focuses on three themes: alluvial fan processes, dynamics of Quaternary alluvial fans and fan sedimentary sequences. Linking the papers is an emphasis on the controls of fan geomorphology, sedimentology and dynamics. This provides a basis for integration between geomorphological and sedimentological approaches, and an understanding how fluvial systems respond to tectonic, climatic and base-level changes.

With its thickness of more than 15 km of strata, covering some 200,000 km2, the Belt basin displays one of the planet's largest, best-exposed, most accessible, and best-preserved sequences of Mesoproterozoic sedimentary and igneous rocks. This volume focuses on research into this world-class province; kindles ideas about this critical era of Earth evolution; and covers aspects of the basin from its paleontology, mineralogy, sedimentology, and stratigraphy to its magmatism, ore deposits, geophysics, and structural geology.

Most of the thirty-four papers contained in this Special Publication arise from the Fourth International Conference on Fluvial Sedimentology held in Spain in 1989. Sections deal with various aspects of sediment transport and hydraulics in flume experiments and modern rivers, the analysis of alluvial facies, geomorphic and structural controls on alluvial sedimentation, alluvial stratigraphy and basin analysis, and finally the exploration and exploitation of ores. A professional reference to the most recent research in fluvial sedimentology. An international expert authorship.

"This memoir brings together results from a multidisciplinary study of the processes that have formed the highest, widest part of the Andean Cordilleran orogenic belt in northern Argentina and Chile. The region features a tectonically erosive forearc, protracted arc magmatism, a high-elevation hinterland plateau and strongly shortened retroarc thrust belt, and a Paleocene-Recent foreland basin system"--

Upwelling systems are special places in the oceans where nutrient-enriched water is brought into the euphotic zone to fuel phytoplankton blooms that, via marine food-web interactions, create the world’s richest fish resources. This book introduces the reader to the interdisciplinary science of upwelling and provides a comprehensive overview of the world’s most productive marine ecosystems in the context of climate variability, climate change and human exploitation. This material presented is suitable for undergraduate and postgraduate study or just for anyone interested to learn about the creation of life in the oceans and how this is compromised by human activities.
