Available in PDF, EPUB and Kindle. Book excerpt: From 1999 to 2003 a multipurpose regional geochemical mapping project, was carried out in Finland, and the NW-part of Russia. An important aim of the project is to define the anthropogenic impact in relation to the natural variations in regional geochemical baselines of heavy metals and other elements over a large area containing several of the largest industrial emitters in Europe but also some of its most pristine areas. Terrestrial moss, the organic layer, stream waters, and the C-horizon soil samples were collected from1085 sites in Russia and 288 sites in Finland, giving an average density of one site per 1000 km2. Both total and aqua regia extractable element concentrations were determined from 2 mm fraction of minerogenic samples, and total concentrations of organic soil samples and terrestrial moss were measured after strong acid leach, bioavailable concentrations of organic layer soil samples were measured, too. Concentrations of more than 50 elements, radionuclides, and other parameters were determined. Different extraction methods were used in order to study the speciation and bioavailability of the elements./pbrbrpMaps showing the distribution of 48 elements and other parameters are included in this atlas. The anomaly patterns of minerogenic C-horizon data are strongly controlled by element distributions in the bedrock. Stream water data are mainly controlled by geological formations and structures both for major and trace elements, but in some cases the influence of anthropogenic activities could be detected as elevated heavy metal concentrations. Anomaly patterns from moss data reflect mainly anthropogenic activities, but in areas such as mountains and tundra the geogenic dust also has a strong influence. It was not possible to detect any long distance airborne transport of heavy metals from industrialized areas to clean arctic regions.

Available in PDF, EPUB and Kindle. Book excerpt: Ancient Supercontinents and the Paleogeography of Earth offers a systematic examination of Precambrian cratons and supercontinents. Through detailed maps of drift histories and paleogeography of each continent, this book examines topics related to Earth’s tectonic evolution prior to Pangea, including plate kinematics, orogenic development, and paleoenvironments. Additionally, this book discusses the methodologies used, principally paleomagnetism and tectonostratigraphy, and addresses geophysical topics of mantle dynamics and geodynamo evolution over billions of years. Structured clearly with consistent coverage for Precambrian cratons, this book combines state-of-the-art paleomagnetic and geochronologic data to reconstruct the paleogeography of the Earth in the context of major climatic events such as global glaciations. It is an ideal, up-to-date reference for geoscientists and geographers looking for answers to questions surrounding the tectonic evolution of Earth. Provides robust paleogeographies of Precambrian cratons based on high-quality paleomagnetic and geochronologic data and critically tested by global geological datasets Includes links to updated databases for the Precambrian such as PALEOMAGIA and the Global Paleomagnetic Database (GPMDB) Presents full-color maps of the drift histories of each continent as well as their paleogeographies Discusses key questions regarding continental drift, the supercontinent cycle, and the geomagnetic dipole hypothesis and analyzes palaeography in the context of Earth’s holistic evolution

This book was released on 2012-10-22 with total page 503 pages. Available in PDF, EPUB and Kindle. Book excerpt: Earth’s present-day environments are the outcome of a 4.5 billion year period of evolution reflecting the interaction of global-scale geological and biological processes punctuated by several extraordinary events and episodes that perturbed the entire Earth system. One of the earliest and arguably greatest of these events was a substantial increase (orders of magnitude) in the atmospheric oxygen abundance, sometimes referred to as the Great Oxidation Event. Volume 1: The Palaeoproterozoic of Fennoscandia as Context for the Fennoscandian Arctic Russia - Drilling Earth Project describes the implementation of the FAR-DEEP drilling project in Arctic Russia. It summarises the knowledge of more than 50 years of largely Russian-led fieldwork, information hitherto virtually unavailable in the west, and provides geological description of drilling areas with an overwhelming illustration of rocks by high-quality, representative photographs. The volume offers a comprehensive review and rich photo-illustration of palaeotectonic, palaeogeographic and magmatic evolution of the Fennoscandian Shield in the early Palaeoproterozoic, and link the evolution of the shield to the emergence of an aerobic Earth system. The volume unfolds the event-based Fennoscandian chronostratigraphy and discusses the chronology of the Palaeoproterozoic global events as the base for a new subdivision of Palaeoproterozoic time. Welcome to the illustrative journey through one of the most exciting periods of planet Earth!

Available in PDF, EPUB and Kindle. Book excerpt: Palaeosurfaces is an area where geologists and geomorphologists can combine their expertise to provide a more holistic treatment of the processes that helped shape the face of the Earth. This volume presents a cross-disciplinary study of the evolution, reconstruction and palaeoevironmental interpretation of ancient paleosurfaces. Topics include palaeoenvironmental studies involving lateritization and bauxitization, palaeokarstification, geochemistry of rock alteration and the identification of ancient palaeosurface elements in both glaciated and tropical terrains.
