Structural Geology textbook

The text book named Structural geology was published by Cambridge University Press in 2010. Illustrations, layout and colors have been given high priority during the writing and production of this book, which is primarily aimed at undergraduate structural geology students. In addition, a large effort has been put into supplementary material, particularly e-learning modules with flash animations, extra problem sets with solutions for instructors, book illustrations in digital format and additional pictures. Below follows more information about these resources. This book is currently being translated for publication in Portugese and Korean.

PS: Unfortunately some of the copies of the 1st edition have a binding problem. This problem has been resolved with the 2nd printing (out in April 2011).

E-learning modules

A series of emodules have been prepared for the book, almost one e-module for each chapter. The most recent versions of these e-modules are found at this website (click here).

Figures

All figures from the book are available for download and free academic use from the publisher's web site.

Photos

I have started to collect photos that may be of interest as supplementary pictures for lecturers and students, located here. If you have illustrative photos that you would be willing to share, please e-mail them to me, and I will include them together with the photographer's name.

Problems

A problem sets has been made, and solutions can be downloaded from the publisher's web site by instructors. I hope to be able to add more later (but it will be a while). Click here for a pdf-file.

Blog

A blog has been set up for discussion of book contents, where comments can be posted and issues can be discussed. News, pictures. localities and other structural geology stuff within the contents of the textbook will also be posted there.

•Page 90: Second line below Equation 5.9: replace >0 by >1

•Page 47: Delete lines 4 and 3 above Section 2.27 (i.e., the statement "Lines that are parallel with ISA do not rotate (generally true for coaxial deformation histories"). It has already been said above.

•Figure 18.20: The small k's have drifted upward from their intended location: They should be subscripts to W similar to the horizontal axes of the graphs.
•Page. 432 Change definition of Dilation to: Dilation (US), Dilatation (UK): Area or volume change, in general used about volume or area increase (volume dilation and area dilation), but mathematically dilation could be either an increase or a decrease (positive and negative dilation). Isotropic dilation involves the same amount of extension in all directions while anisotropic dilation does not. A common example of anisotropic dilation is uniaxial strain.
