The History of Geophysics in Southern Africa


Book Description

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.

Geophysics in the Affairs of Man


Book Description

Geophysics in the Affairs of Man describes how geophysics has affected human affairs, with emphasis on the geophysical enterprise as an interplay of technical, social, and economic factors. Many of the key and intriguing developments that took place within several major fields of geophysics are divided into seven epochs, roughly broken into decades. Topics covered include the origins of the profession of geophysics, earth physics and oceanography, and geophysical aspects of undersea warfare. This book is comprised of nine chapters and begins with a discussion on some antecedents to the modern-




Near-surface Geophysics


Book Description

Part 1, "fundamentals", includes magnetic and electrical methods, subsurface geophysics, near-surface seismology, electromagnetic induction, and ground-penetrating radar. Part 2, "applications", includes determination of physical properties, multimethod surveys and integrated interpretations, and model-based survey planning, execution, and interpretation.




Large Igneous Provinces


Book Description

Large igneous provinces (LIPs) are intraplate magmatic events, involving volumes of mainly mafic magma upwards of 100,000 km3, and often above 1 million km3. They are linked to continental break-up, global environmental catastrophes, regional uplift and a variety of ore deposit types. In this up-to-date, fascinating book, leading expert Richard E. Ernst explores all aspects of LIPs, beginning by introducing their definition and essential characteristics. Topics covered include continental and oceanic LIPs; their origins, structures, and geochemistry; geological and environmental effects; association with silicic, carbonatite and kimberlite magmatism; and analogues of LIPs in the Archean, and on other planets. The book concludes with an assessment of LIPs' influence on natural resources such as mineral deposits, petroleum and aquifers. This is a one-stop resource for researchers and graduate students in a wide range of disciplines, including tectonics, igneous petrology, geochemistry, geophysics, Earth history, and planetary geology, and for mining industry professionals.







History of Geomorphology and Quaternary Geology


Book Description

These papers deal with various aspects of the histories of geomorphology and Quaternary geology in different parts of the world. They include: the origin of the term 'Quaternary', histories of ideas and debates relating to aspects of fluvial geomorphology, glacial geomorphology and glaciation, desert dunes and the geology of Australia, peneplains in China, a palaeo-Tokyo Bay in Japan, together with biographies of Charles Cotton, Valerija Čepulytė and Česlovas Pakuckas that highlight their respective contributions to the disciplines of geomorphology and Quaternary geology.
