Readings

There is no assigned text for purchase. Instead, the following texts are available in LS 116.

D: Dennis, Structural Geology, An Introduction
S: Suppe, Principles of Structural Geology
B: Billings, Structural Geology
R: Ragan: Structural Geology, An Introduction to Geometrical Techniques

Numbers after text abbreviations refer to chapters, letters to appendices. You’ll note there’s a lot more reading associated with the lab. Also, many lab techniques are explained in detail at http://www.uwgb.edu/dutchs/STRUCTGE/LABMAN.HTM
