A recent national survey of geology students indicated that, In a subject so fundamental and yet so varied, every although they saw the need for a basic training in map geologist will have his own views on geological maps - the work, the three-dimensional aspects involved formed the matters needing emphasis, the best methods of interpreta single most difficult part of an introductory geology tion, good examples of maps, and so on. Instructors may course, and that it was generally taught in a way both ab therefore urge in their taught courses different priorities stract and dull. At the same time, there was no book which from those given here, and, although a wide range of maps puzzled students could turn to for explanations; no book and map exercises is included, will prefer to continue to which told them more about real geological maps. This use their own 'pet' examples. But this is meant primarily to book is an attempt to fill that need. It is based on the view be a book for the student - to turn to for clarification, for that in these days of increasing specialisation the geological further information, and simply to learn a little more about map remains the vital coordinating document, and that the geological maps.
Geological maps remain a fundamental tool in earth science. They provide an essential link as geology continues to expand and diversify; computer methods are adding further to their power and versatility. Hence it is more important than ever that students of the Earth are familiar with the principles of working with geological maps. This book introduces geological maps in a clear, readable and practical way. Abstract and idealistic examples (so common in other treatments of the subject) have been avoided and almost all the illustrations used are taken from real maps and real situations around the world. This new edition has been substantially revised and provides worked solutions to the numerous map exercises. Extensive use of three dimensional diagrams and eight colour maps coupled with the up-to-date and lively text will ensure that this book remains the standard reference for students of earth science. New chapters on wider uses of geological maps, such as in environmental planning and in understanding the landscape around us, will also make the book indispensable for environmental scientists and geographers, and of interest to amateur geologists.

'An Introduction to Geological Structures & Maps' is a concise text that leads the students in easy stages from the simplest ideas on geological structures right through to the more advanced geological mapping techniques. The approach this book adopts is designed to help students with little or no supervision: each new topic is simply explained and illustrated by figures, and exercises are set on successive maps. If students are unable to complete a problem, they can read on to obtain more specific instructions on how theory may be used to solve the problem in question. This considerably enlarged seventh edition aims to make the book even more user friendly and bring it into line with present trends in map syllabuses. This edition includes photographs that will significantly add to the understanding of geological structures already illustrated by text-figures and block diagrams in the appendix. The appendix has been fully updated and now includes completed sections of all maps and solutions to the map problems, which enables the reader to check that his or her attempts have been successfully carried out.
A Practical Guide to Surface and Subsurface Map Interpretation
Author: Richard H. Groshong
Publisher: Springer Science & Business Media
This is a handbook of practical techniques for making the best possible interpretation of geological structures at the map scale and for extracting the maximum amount of information from surface and subsurface maps. Quantitative methods are emphasized throughout and analytical solutions are given. Interpretation strategies are defined for GIS or CAD users, yet are simple enough to be done by hand. This book will help users produce better geological maps, judge the quality of existing maps, and locate and fix mapping errors.
This textbook is designed to aid the student in geological map interpretation. The book starts with basic concepts such as dip and strike, and progresses through a variety of exercises based on folds, faults and unconformities, up to and including the interpretation of Geological Survey Maps. In order to give a sense of reality to the text, frequent reference is made to actual examples on which many of the problem maps are based. Also included in the text are exercises concerned with bore-hole interpretation and correlation. The book, which is in two sections, is unique in that the second section contains worked solutions to the questions set in the first half.

Introduction to Geological Maps and Structures describes the basic methods to interpret and attain a better understanding of geological maps. The book describes the nature and preparation of geological maps, and then covers topics such as solid and drift maps, geological boundaries, sections, and the use of symbols. The book explains sedimentary rocks, outcrop patterns, and the topographic representation of geological structures. The text also addresses the geometry of folds and folding when pre-existing surfaces are distorted into zigzag patterns. The author explains in detail the morphology of folded layers and the mechanism involved in folding. He goes on to interpret the formation of outcrop patterns, as well as the structure of a cylindrical and cylindroidal fold patterns. The author also describes the different structures that result from the brittle fractures present in rocks that undergo massive stress. Of interest is the presentation of how fissures and mineral veins are formed and deposited. The author then discusses earth movements resulting in angular unconformities known as stratigraphic break. These breaks in the stratigraphic record, such as diastems, non-sequences, paraconformities, or disconformities, can be interpreted as the intervals of geological time. The book then explains the nature of tectonic maps, which involves features arising from the continental crust, and how these maps are different from geological maps that show the outcrop of lithostratigraphic units. Geologists, cartographers, meteorologists, seismologists, land use developers, and students of the earth sciences will find this book valuable.
