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.

Syntheses of the geology of major areas of the Earth's crust are increasingly needed in order that the features of, and the problems associated with, the secular evolution of the continents can be understood by a wide audience. Southern Africa is fortunate in having a remarkable variety of geological environments developed without many breaks over 3. 8 Ga, and many of the rock groups are household names throughout the geological world. In one respect the geology of Southern Africa is particularly important: cratonization clearly began as early as 3. 0 Ga ago, in contrast to about 2. 5 Ga in most other continental areas such as North America. This book documents very well the remarkable change in tectonic conditions that took place between the Early and Mid-Precambrian; we have here evidence of the very earliest development of rigid lithospheric plates. This book is a tribute to the multitudes of scientists who have worked out the geology of Southern Africa over many years and decades. Whatever their discipline, each provided a step in the construction of this fascinating story of 3. 8 Ga of crustal development. In the book the reader will find a detailed review of the factual data, together with a balanced account of interpretative models without the indulgence of undue speculation. One of its attractions is its multidisciplinary approach which provides a stimulating challenge to the reader.

ISBN: 3319689207

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.

This book presents the results of seismic data analysis and interpretation based on nearly one million seismic events. This seismicity was induced by the caving process in four copper mines, each located on a different continent. The book not only serves as an interpretation guide, it also illustrates the benefits of evaluating data from different mines: How to establish which seismic data base is faulty and why The formation of a universal seismic response to the caving process Indisputable evidence that hydro-fracturing improves underground safety This book invites discussion on more general aspects of research, such as: Basic research, applied research and implementation Predicting mine-induced seismic events Quantitative versus qualitative seismology Research versus pseudo-research What is genuine research? [In the Parlabora Mine] Stefan has demonstrated that [the] use of the seismic system was a very practical means of monitoring the progression of the cave up to and beyond break through into the open pit above. The seismic system was vital in drawing up the undercutting and seismic protocols and determining the maximum potential seismic hazard level. Peter Townsend Retired Mine Manager and Consultant I consider Stefan the pioneer of using microseismic data to provide understanding of the mechanism and progress of cave mining. Science has advanced considerably since the use of less than reliable extensometers to monitor the cave back position and Stefan was leading this advance. (...)This book provides a lot of useful insight[s] in how we can best understand the data that we (...) gather and how to change this data into useful information. Neil Hepworth C. Eng, MIMMM, Geomin Consultorio – Brazil. Consultant Mining and Geotechnics Stefan mine seismology trilogy is (...) a comprehensive tutoring on how to analyse and interpret mine induced seismicity. This coaching is based on multiple practical examples (...) presented from the problem to be solved [with] input data tests followed by analysis and interpretation. This last is presented with many details that explain the whole process. Mahdi Bayuargo, ST, MAScPT. Duaem Gada Bayuagus Managing Director

ISBN: 1928480098

This eight-chapter volume, African Military Geosciences: Military History and the Physical Environment, is a tour-de-force covering nearly 500 years of African military geosciences. It is a truly global book that reveals keen insights into regional, national and international military-forces activities centered in Africa and how the understanding of geosciences plays important roles. It is written for the specialist, but also attractive to the general military buff - well referenced and illustrated with figures from primary sources, historical catalogues and compendia. The publication explores the "e;age of sail"e;, harbour defenses, the trafficability of desert environments and marshes, as well as climate controls on sailing or land battles. There is even insight into an elite artillery unit staffed by women during Second World War - essentially covering the whole gamut. Ultimately, the reader explores a nearly 500-year journey around the African continent and beyond.
