"This volume contains a sizable suite of contributions dealing with regional impact records (Australia, Sweden), impact craters and impactites, early Archean impacts and geophysical characteristics of impact structures, shock metamorphic investigations, post-impact hydrothermalism, and structural geology and morphometry of impact structures - on Earth and Mars"--
This book addresses and reviews many of the still little understood questions related to the processes underlying planetary magnetic fields and their interaction with the solar wind. With focus on research carried out within the German Priority Program ”PlanetMag”, it also provides an overview of the most recent research in the field. Magnetic fields play an important role in making a planet habitable by protecting the environment from the solar wind. Without the geomagnetic field, for example, life on Earth as we know it would not be possible. And results from recent space missions to Mars and Venus strongly indicate that planetary magnetic fields play a vital role in preventing atmospheric erosion by the solar wind. However, very little is known about the underlying interaction between the solar wind and a planet’s magnetic field. The book takes a synergistic interdisciplinary approach that combines newly developed tools for data acquisition and analysis, computer simulations of planetary interiors and dynamos, models of solar wind interaction, measurement of ancient terrestrial rocks and meteorites, and laboratory investigations.
This monograph illustrates how geophysical methods can be used to explore the subsurface of our Earth. Geophysical method (magnetic, gravity, seismic refraction and 2D resistivity) and geotechnical method (boring) were applied to study the characterization of the subsurface and to prove that the study area was a meteorite impact area. The study continues with the geophysical data acquisition and processing techniques together with integration of the results (including borehole) for better interpretation. A thorough integration of the archaeological data with geophysical data successfully delineates the history of the area investigated. This monograph was compiled accordingly to capture reader’s interest and to ease their understanding. Hence, it would be of interest especially to students in archaeology, engineering, environmental, geology and geophysics courses. This monograph definitely provides new knowledge for the readers and encourages researchers to study subsurface of the Earth using geophysical methods.

"The third volume of the series “Large Meteorite Impacts” provides an updated and comprehensive overview of modern impact crater research. In 26 chapters, more than 90 authors from Europe, the United States, Russia, Canada, and South Africa give a balanced, firsthand account of the multidisciplinary field of cratering science, with reports on field studies, geophysical analyses, and experimental and numerical simulations. Nine chapters focus on structure, geophysics, and cratering motions of terrestrial craters. Recent advances in impact ejecta studies and shock metamorphism are assembled, each with seven chapters, and three chapters extend the scope from a terrestrial to a planetary perspective."--pub. desc.
This book aims to impart knowledge on tropical climate towards engineering and environmental field and 2D resistivity method in general. It is written in its simplest way, illustrated by examples and illustrations to enhance readers’ understanding of the general concepts and governing theories relating to electrical methods and how they are applied to solve problems affecting the subsurface of the tropical regions. The discussion centres around the common problems, detection using geophysical method of 2D resistivity, reliability of the method to depicts the subsurface, and solutions to overcome the problems related to tropical region. Examples of 2D resistivity survey in various fields were presented in this book including structural geology, groundwater exploration, mineral prospecting and quarry management. Others are seawater intrusion, land subsidence, geoengineering and environmental hazards. This book is suitable as a reference and companion to geophysics students, professional geophysicists, geologists and civil engineers as well as personnel involved in subsurface electrical works.
Presents a collection of papers which appear in the September-October 2010 Geophysics special section, written by recognised experts in various areas of exploration geophysics, plus an additional group of papers drawn from Geophysics which address areas beyond those invited articles. The result is a snapshot of the state-of-the-art in the field.
