Structural Geology Lab Manual by David Allison

A structural geology laboratory manual comes always handy to anyone dealing with maps, cross-sections or stereograhic nets. Even those experienced geologists who have left their university days left behind the mist of time need to have one. Many techniques are learnt, but soon leave room in our room for other issues that may be even more important (e.g. telephone number of the canteen waitress, local pubs near an outcrop, and so forth...)

There are methods in structural geology that if one doesn't use them regularly, soon become rusty and we simply need to refresh them from time to time: how to rotate lines and planes with a stereonet, how to solve a three-point problem, etc.

Today I'd like to present you an excellent structural geology lab manual, written by David T. Allison, an associate professor of geology of the Department of Geology and Geography of the University of South Alabama:


The manual contains explanations and exercises on attitude measurements, true and apparent dips, three-point problems, stereographic projections, rotations with the stereonet, stereograms, geologic mapping and cross-section construction, thickness and outcrop problems ans statistical techniques.
It is written in a very approachable style, and completed with good figures that will help anyone to understand and practise the foundations of our profession or studies.

The text makes reference to several spreadsheets that you can find in the homepage of the author:
