An Introduction toGeological Structuresand Maps
Fifth Edition

Through successive editions additional material had been fitted into the existing 64 pages. Now an enlarged fifth edition provides the opportunity to add new maps and more explanatory text. The aim is to make the progression from the simplest map to the most difficult more gradual by increasing the number of steps. A further three maps (out of 5 new maps) are not dependent on structure contours for their solution. The point is reemphasized that the student should always examine a map with a view to deducing the basic structures from outcrop patterns (in relation to the topography), as far as this is possible, even on maps where the precise solution is dependent on structure contours. The opportunity has been taken to update terminology, particularly of fold and fault structures. The order of presentation has been radically changed from earlier editions and it is hoped that this will be found to be more logical. In addition to problem maps based on, or adapted from, published geological maps, reference is made in each chapter to British Geological Survey maps (generally on the
1 :50,000 scale). They are selected to illustrate the problems dealt with in each chapter. While it is appreCiated that only some readers will have access to these maps, the necessity of relating problem maps to 'real' geological maps justifies the small amount of the book devoted to these exercises.
My thanks are due to friends and colleagues for their continuing interest and helpful suggestions. I am particularly grateful to Dr K.A. Moseley and Dr. D.E. Roberts. Without the expertise and diligencen of Dr R. Pickering this edition would not have been possible. My thanks to Mr Carl Burness for drafting the new maps and diagrams and revising many of the figures.
Readers wishing to pursue the subject further are recommended the following reading:
- Advanced Geological Map Interpretation, F. Moseley, Edward Arnold, 1979.
- The use of Stereographic Projections in Structural Geology, F.C. Phillips, Edward Arnold,1954.
- The Mapping of Geological Structures, K. McClay,
Geological Society of London Handbook,1987.
