Geologists must be able to “read” a geological map. That means interpreting the vertical dimension through the 2D view represented on the map and at different scales. The main objective of this book is to help students during this difficult learning process. Based on an abundant iconography (field photos, maps, cross-sections) and on basics in mathematics and mechanics, the book dissects the geometry of emblematic geological structures and objects in order to build 3 D models, printable in 3D. The book is dedicated to structural geology with a particular emphasis on kinematics of faulting and folding and on salt tectonics (chapters III, IV and V). The origin of continental great unconformities and oceanic break-up unconformities is also discussed (chapter II). The audience of the book is broad and includes (under)graduate students in Earth Sciences, professors of Natural Sciences, and professional or amateur geologists.

Learning to draw field sketches is an essential task for geologists, which is often overlooked. This book presents simple techniques, useful tips and detailed examples to teach geologists how to draw rocks and what essential features need to be recorded. It is a book on how to use art in science.

The Gold-Standard “Bible” for Applied Subsurface Geological Mapping: Extensively Updated for Working Teams’ Latest Advances Long recognized as the most authoritative, practical, and comprehensive guide to structural mapping methods, Applied Three-Dimensional Subsurface Geological Mapping, Third Edition, has been thoroughly updated to reflect recent technical developments, with an emphasis on shale play basins, horizontal drilling, unconventional resources, and modern workflows. The authors of this edition have more than a century of collective experience in hydrocarbon exploration and development, in major, large, independent companies throughout the world. In this long-awaited update, they present revised and new chapters on computer mapping, shale basin exploration, and prospect reserves and risk. They introduce key innovations related to shale reservoirs, hydraulic fracturing, and deviated, horizontal, and directional wells, along with expanded discussions of computer interpretations and mapping. Throughout, the book links theory and practice based on fundamental geoscience principles. These principles will help you integrate all available geological, geophysical, and engineering data, to generate more reasonable and viable subsurface interpretations, and to construct maps that successfully identify reserves. Master core principles and proven methods for accurate subsurface interpretations and mapping Construct subsurface maps and cross-sections from well logs, seismic sections, and outcrop data Work effectively with horizontal and directionally drilled wells and directional surveys Use powerful well log-correlation techniques Construct viable fault and horizon structure maps Balance and interpret compressional, extensional, and strike-slip structures Distinguish between the different structure styles and the characterization of growth structures Understand isochore and isopach maps This book is indispensable for every integrated working team, consisting of geologists, geophysicists, and engineers, that prepares subsurface geological interpretations and maps, as well as for every manager, executive, and investor who uses or evaluates prospects.

Applied Subsurface Geological Mapping, With Structural Methods, 2nd Edition is the practical, up-to-the-minute guide to the use of subsurface interpretation, mapping, and structural techniques in the search for oil and gas resources. Two of the industry's leading consultants present systematic coverage of the field's key principles and newest advances, offering guidance that is valuable for both exploration and development activities, as well as for "detailed" projects in maturely developed areas. Fully updated and expanded, this edition combines extensive information from the published literature with significant material never before published. The authors introduce superior techniques for every major petroleum-related tectonic setting in the world. Coverage includes: A systematic, ten-step philosophy for subsurface interpretation and mapping The latest computer-based contouring concepts and applications Advanced manual and computer-based log correlation Integration of geophysical data into subsurface interpretations and mapping Cross-section construction: structural, stratigraphic, and problem-solving Interpretation and generation of valid fault, structure, and isochore maps New coverage of 3D seismic interpretation, from project setup through documentation Compressional and extensional structures: balancing and interpretation In-depth new coverage of strike-slip faulting and related structures Growth and correlation consistency techniques: expansion indices, Multiple Bischke Plot Analysis, vertical separation versus depth, and more Numerous field examples from around the world Whatever your role in the adventure of finding and developing oil or gas resources–as a geologist, geophysicist, engineer, technologist, manager or investor–the tools presented in this book can make you significantly more effective in your daily technical or decision-oriented activities.

Despite the modern dominance of computer graphics programs and digital cameras, the ability todraw geological structures manually remains a necessity in academic geology and beyond. Drawings serve for quick and simple documentation in the field or at the microscope. They can be applied as a language of their own as well as be adapted to suit specific requirements. Moreover, geological drawing improves observational ability and contributes to the understanding of geological structures and structure-forming processes. Geological drawing is assisted scientific thinking. Drawing Geological Structures provides undergraduate as well as graduate and practicing geologists with a thorough, step-by-step practical guide to the art of geological drawing. Beginning with the basics, the book covers thin sections, sample sections, samples and geological stereograms. The chapters provide examples of how drawings evolve and are complemented by exercises, allowing the reader to practice their drawing prior to going out into the field or working at the microscope. Users of this unique guide will develop their knowledge and technical vocabulary whilst also improving their drawing skills.

This combination of text and lab book presents an entirely different approach to structural geology. Designed for undergraduate laboratory classes, it provides a step-by-step guide for solving geometric problems arising from structural field observations. The book discusses both traditional methods and cutting-edge approaches, with emphasis given to graphical methods and visualization techniques that support students in tackling challenging two- and three-dimensional problems. Numerous exercises encourage practice in using the techniques, and demonstrate how field observations can be converted into useful information about geological structures and the processes responsible for creating them. This updated fourth edition incorporates new material on stress, deformation, strain and flow, and the underlying mathematics of the subject. With stereonet plots and solutions to the exercises available online at www.cambridge.org/ragan, this book is a key resource for undergraduates, advanced students and researchers wanting to improve their practical skills in structural geology.

This collection of papers on geophysical inversion contains research and survey articles on where the field has been and where it's going, and what is practical and what is not. Topics covered include seismic tomography, migration and inverse scattering.
