Late Quaternary Tephrochronology Of Nevado De Toluca Volcano Central Mexico

The book presents an up-to-date, detailed overview of the Quaternary glaciations all over the world, not only with regard to stratigraphy but also with regard to major glacial landforms and the extent of the respective ice sheets. The locations of key sites are included. The information is presented in digital, uniformly prepared maps which can be used in a Geographical Information System (GIS) such as ArcView or ArcGIS. The accompanying text supplies the information on how the data were obtained (geomorphology, geological mapping, air photograph evaluation, satellite imagery), how the features were dated (14C, TL, relative stratigraphy) and how reliable they are supposed to be. All references to the underlying basic publications are included. Where controversial interpretations are possible e.g. in Siberia or Tibet, this is pointed out. As a result, the information on Quaternary glaciations worldwide will be much improved and supplied in a uniform digital format. The information on the glacial limits is compiled in digital form by the coordinators of the project, and is available for download at: http://booksite.elsevier.com/9780444534477/ Completely updated detailed coverage of worldwide Quaternary glaciations Information in digital, uniformly prepared maps which can be used in a GIS such as ArcView or ArcGis Step-by-step guideline how to open and use ArcGis files Possibility to convert the shapefiles into GoogleEarth kmz-files Availability of chronological controls

This impressive scientific resource presents up-to-date information on ten thousand years of volcanic activity on Earth. In the decade and a half since the previous edition was published new studies have refined assessments of the ages of many volcanoes, and several thousand new eruptions have been documented. This edition updates the book’s key components: a directory of volcanoes active during the Holocene; a chronology of eruptions over the past ten thousand years; a gazetteer of volcano names, synonyms, and subsidiary features; an extensive list of references; and an introduction placing these data in context. This edition also includes new photographs, data on the most common rock types forming each volcano, information on population densities near volcanoes, and other features, making it the most comprehensive source available on Earth’s dynamic volcanism.

Preceramic Mesoamerica delivers cutting-edge research on the Mesoamerican Paleoindian and Archaic periods. The chapters address a series of fundamental questions in American archaeology including the peopling of the Americas, human adaptations to late glacial landscapes, the Neolithic transition, and the origins of sedentism and early village life. This volume presents innovative and previously unpublished research on the Paleoindian and Archaic periods and evaluates current models in light of new findings. Examples include breakthroughs in dating Mesoamerica’s earliest sites and their implications for models of hemispheric colonization; the transition to postglacial patterns of settlement and subsistence; divergent pathways to initial sedentism; the possibility of Archaic-period monumentality; changing patterns of interregional exchange and interaction; and debates surrounding the origins of agriculture, ceramics, and full-time village life. The volume provides a new perspective on the Mesoamerican Preceramic for students and scholars in archaeology, anthropology, and history. Readers will come to understand how the Preceramic contributed to the emergence of the cultural traditions that anthropologists recognize as Mesoamerica.

Pyroclastic Rocks is the first modern comprehensive treatment of what they are and how they were formed. The subject is discussed against a background of plate tectonics theory and modern advances in volcanology, sedimentology and igneous petrology. The book provides a thorough discussion of magmatic volatiles and pyroclastic processes as well as magma-water interactions. Most of the book is concerned with the wide spectrum of pyroclastic rocks formed on land and under water and by fallout and various flowage mechanisms. Diagenetic processes by which pyroclastic particles are transformed into rocks are discussed in detail. The stratigraphic and tectonic importance of pyroclastic rocks are illustrated using selected case histories. This uniquely integrated account of pyroclastic processes, particles and rocks will prove a valuable aid in reconstructing dynamic aspects of earth evolution as well as predicting future volcanic hazards; understanding sedimentary basins containing petroleum and gas deposits; locating ore deposits in volcanic complexes and heat sources in geothermal prospecting; and facilitating stratigraphic analysis in complex volcanic terrains.

Accompanying CD-ROM, entitled Supplementary materials to Stratigraphy and geology of volcanic areas, includes three geologic maps in Adobe Acrobat PDF files.
