About this Item

Print on Demand. This book introduces the fundamental principles of geological map-reading to students as they advance from classroom theory into field practice. The author's approach is to minimize trigonometrical calculations, using a method of reckoning slopes and dips as gradients that can be directly measured from the map itself. Equipping readers with a portable scale and protractor, the book begins with an overview of topographical maps and how to read them to interpret land surface relief and slope. It then moves on to explore how to read geological maps, which reveal the distribution of various rock layers at the ground surface and how these layers fold and fault. The book includes many helpful diagrams and illustrations to support the text and aid the reader through concepts such as strike, dip, and outcrop, as well as practical advice on estimating the thickness of various formations and the throw of faults. Presented in clear and accessible language, this book is an essential companion for geology students in the early stages of encountering geological maps. This book is a reproduction of an important historical work, digitally reconstructed using state-of-the-art technology to preserve the original format. In rare cases, an imperfection in the original, such as a blemish or missing page, may be replicated in the book.

About this title

Synopsis

Master geological map-reading with clear, practical guidance for real-world interpretation.

This nonfiction guide teaches you to visualize geological maps in three dimensions, recognize how structures like dykes, faults, and folds shape outcrops, and use simple geometry to interpret boundaries. It emphasizes reading the information directly from the map face and using sections to illustrate relationships, without overreliance on plotted data alone.

• How to identify intrusive bodies, faults, and folds on a map and what they imply for the landscape.
• Ways to measure throw and understand boundary shifts from dip, strike, and contour data.
• Strategies for applying the concepts to both large and small-scale maps, with practical caveats.
• Tips for visualizing geology in three dimensions to better predict subsurface relations.

Ideal for students and professionals who want a clear, hands-on approach to reading geological maps and understanding structural geology in field settings.
