Focusing on the Precambrian in the central part of the Fennoscandian Shield, the book combines the results from modern geological and geophysical research into a detailed petrologic, lithologic, and structural synthesis and interpretation of the Archean and Proterozoic of Finland. It will be of value to anyone interested in the evolution of the shield in particular and in Precambrian geology in general.

Since 1964, the time when the Upper Mantle Project was started, the Precambrian continental crust has been studied in considerable detail in many areas. Multidisciplinary studies, using modern tools and techniques have resulted in increasing levels of accuracy. The Precambrian continental crust has been subjected to several thermal events and multiple episodes of deformation. These events have obliterated the scenario produced by early events and present-day efforts are directed towards evaluating the cause-effect processes of each event. How far back the known geological processes of the Phanerozoic can be extended into the Precambrian is one of the main questions. The present volume provides data and interpretations which will help in formulating the answer to some of these questions.The book contains 30 contributions resulting from researches on almost all the important Precambrian terranes.

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!

This volume is the final outcome of a conference designed to wrap up IOCP Project 157 (" Early Organic Evolution and Mineral and Energy Resources ") after a decade of prolific activity. The picturesque solitude of Maria Laach Abbey in the Eifel Mountains (FRO) provided the appropriate setting for a conclave of some 80 specialists from the various walks of the field who, during the week of Sept. 19 - 23, 1988, strived hard to define the state of the art in the principal segments of this Earth Science frontier. The following pages contain the essence of the conference transactions, giv ing a vivid cross-section of the activities pursued by IOCP Project 157 during its final years. The coverage of topics is not necessarily complete, but rather eclec tic in part. With regard to single papers dealing with modern analogues of ancient processes, the book title might even be considered a grave misnomer. Neverthe less, all contributions relate to the subject in the widest sense, and the reader should be reminded that much of the heterogeneity reflected by the volume de rives from the fact that it is primarily a research report from a highly inter disciplinary field rather than a textbook.

The main goal of this book is to provide a modern comprehensive statement on the Earth's Precambrian crust. It uses geographic and tectonic location, lithostratigraphy, geochronology, and petrogenesis as a basis for considering Precambrian coastal evolution--including the role of plate tectonics. Detailed consideration is given to the endogenic and exogenic processes which formed the continental crust and also to its subsequent secular evolution across Precambrian time**An essential reference volume for every Precambrian geologist.

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
