Geophysics is a comparatively young science which only evolved as a distinct discipline during the 19th century. However, its phenomena (like earthquakes, tsunamis, volcanic eruptions and lightning) had been objects of fear, curiosity and speculation since ancient times. In this book, Johan de Beer and his research team reveal that geophysical activity in South Africa can be traced back to as early as 1488. This is a truly astonishing revelation which deserves to be firmly entrenched as part of the country?s proud history. The book also discusses the history and formation of South African geophysical institutions that made a huge and seldom acknowledged contribution to the technological development of southern Africa.

This book focuses on the geological evolution of Southwest (SW) Gondwana and presents state-of-the-art insights into its evolution. It addresses the diachronic assembly of continental fragments derived from the break-up of the Rodinia supercontinent later amalgamated to build SW Gondwana during the Neoproterozoic–Cambrian transition, which on a global scale includes parts of present-day South America, Africa and Madagascar. The book presents 24 state-of-the-art reviews including the most crucial controversies. Most experienced scientists about the geology of SW Gondwana from Europe, Africa, South America and Australia present contributions on key areas addressing the interactions between the main cratons and fold belts on both sides of the South Atlantic Ocean. Chapters related to the geology of the major Archean- Paleoproterozoic cratons and Neoproterozoic Brasiliano/Pan-African fold belts enable readers to gain an in-depth understanding of the tectonometamorphic and magmatic evolution of SW Gondwana. The book covers a wide range of issues including metallogenetic, sedimentary, paleobiological and paleoclimatic processes and allows a deep insight into this key period of the Earth’s evolution.

The magnetotelluric method is a technique for imaging the electrical conductivity and structure of the Earth, from the near surface down to the 410 km transition zone and beyond. This book forms the first comprehensive overview of magnetotellurics, from the salient physics and its mathematical representation to practical implementation in the field, data processing, modeling and geological interpretation. Electromagnetic induction in 1-D, 2-D and 3-D media is explored, building from first principles, and with thorough coverage of the practical techniques of time series processing, distortion, numerical modeling and inversion. The fundamental principles are illustrated with a series of case histories describing geological applications. Technical issues, instrumentation and field practices are described for both land and marine surveys. This book provides a rigorous introduction to magnetotellurics for academic researchers and advanced students, and will be of interest to industrial practitioners and geoscientists wanting to incorporate rock conductivity into their interpretations.

The book deals with the record of important Neoproterozoic to Early Palaeozoic events in southwestern Gondwana, that heralded the Cambrian explosion and the dawn of modern ecosystems. It contains a detailed account of the Neoproterozoic to Cambrian geological record in a poorly-known part of the world, which is at the same time key to understand fundamental processes at the Proterozoic-Cambrian transition. The emphasis is placed on litho-, bio-, chemostratigraphy and magmatism. The palaeoclimatic, tectonic, evolutionary radiation and extinction events and associated mineralizations will be identified and discussed. A synthesis of all data is provided at the end of the book, integrating the data from all cratons and fold belts in southwestern Gondwana. The events will be individualized, their impact discussed and correlations between different successions both within and outside Gondwana proposed.The book is organized in three sections. Section one is an introduction to the neoproterozoic and Cambrian seen as a time of upheavals, extremes and innovations. Section two comprises nineteen chapters dealing with the neoproterozoic-Cambrian events in southwestern Gondwana. Section three will provide a synthesis on every major topic, and a critical assessment of the global implications of the presented data. - The book deals with the record of important Neoproterozoic to Early Palaeozoic events in southwestern Gondwana, that heralded the Cambrian explosion and the dawn of modern ecosystems - It contains a detailed account of the Neoproterozoic to Cambrian geological record in a poorly-known part of the world, which is at the same time key to understand fundamental processes at the Proterozoic-Cambrian transition - The emphasis is placed on litho-, bio-, chemostratigraphy and magmatism

Permeability is the primary control on fluid flow in the Earth’s crust and is key to a surprisingly wide range of geological processes, because it controls the advection of heat and solutes and the generation of anomalous pore pressures. The practical importance of permeability – and the potential for large, dynamic changes in permeability – is highlighted by ongoing issues associated with hydraulic fracturing for hydrocarbon production (“fracking”), enhanced geothermal systems, and geologic carbon sequestration. Although there are thousands of research papers on crustal permeability, this is the first book-length treatment. This book bridges the historical dichotomy between the hydrogeologic perspective of permeability as a static material property and the perspective of other Earth scientists who have long recognized permeability as a dynamic parameter that changes in response to tectonism, fluid production, and geochemical reactions.
