Rock fractures control many of Earth's dynamic processes, including plate-boundary development, tectonic earthquakes, volcanic eruptions, and fluid transport in the crust. An understanding of rock fractures is also essential for effective exploitation of natural resources such as ground water, geothermal water, and petroleum. This book combines results from fracture mechanics, materials science, rock mechanics, structural geology, hydrogeology, and fluid mechanics to explore and explain fracture processes and fluid transport in the crust. Basic concepts are developed from first principles and illustrated with worked examples linking models of geological processes to real field observations and measurements. Many additional examples and exercises are provided online, allowing readers to practise formulating and quantitative testing of models. Rock Fractures in Geological Processes is designed for courses at the advanced undergraduate and graduate level but also forms a vital resource for researchers and industry professionals concerned with fractures and fluid transport in the Earth's crust.

Rock fractures play a major role in many geological processes, such as plate tectonics, earthquakes, volcanic eruptions and fluid transport in the earth’s crust. The present volume contains the abstracts of all presentations of the symposium „Rock Fractures in Geological Processes“, held on 26-27 November 2013 in London honouring the 60th birthday of Agust Gudmundsson, chair in Structural Geology, Royal Holloway University of London, a leading expert in the field and author of a well known text book of the same title. The symposium covered all topics related to fractures in the earth’s crust, e.g., crustal stresses, rock mechanical properties, field analysis of fractures – from joints and faults to mineral veins and dykes -, analytical, analogue and numerical models of fractures and related fluid transport, as well as the activity of faults and volcanoes including calderas, and economic aspects such as exploration and exploitation of hydrocarbons and geothermal energy.
Rock Fractures and Fluid Flow

Release Date: 1996-09-10
Scientific understanding of fluid flow in rock fractures--a process underlying contemporary earth science problems from the search for petroleum to the controversy over nuclear waste storage--has grown significantly in the past 20 years. This volume presents a comprehensive report on the state of the field, with an interdisciplinary viewpoint, case studies of fracture sites, illustrations, conclusions, and research recommendations. The book addresses these questions: How can fractures that are significant hydraulic conductors be identified, located, and characterized? How do flow and transport occur in fracture systems? How can changes in fracture systems be predicted and controlled? Among other topics, the committee provides a geomechanical understanding of fracture formation, reviews methods for detecting subsurface fractures, and looks at the use of hydraulic and tracer tests to investigate fluid flow. The volume examines the state of conceptual and mathematical modeling, and it provides a useful framework for understanding the complexity of fracture changes that occur during fluid pumping and other engineering practices. With a practical and multidisciplinary outlook, this volume will be welcomed by geologists, petroleum geologists, geoengineers, geophysicists, hydrologists, researchers, educators and students in these fields, and public officials involved in geological projects.
