• "Structural Geology" by Haakon Fossen (Cambridge University Press) – The gold standard. Look for the 2nd or 3rd edition PDF; it features full-color graphics and online supplements.
• "Structural Geology of Rocks and Regions" by George H. Davis – Strong on field techniques.
• "Fundamentals of Structural Geology" by David D. Pollard – Mathematics-heavy, ideal for graduate students.
• "Modern Structural Practice" by R.A. Ragan – A classic field workbook, often available as a scanned PDF.

In the digital age, carrying a 500-page hardback textbook into the mountains is impractical. Having a high-quality structural geology PDF on a tablet or smartphone allows for: In the digital age, carrying a 500-page hardback

Chapter 10: Glossary of Key Terms

| Term | Definition | | :--- | :--- | | Boudinage | Stretched and segmented competent layer in a ductile matrix. | | Crenulation | Small-scale wrinkles in an existing foliation. | | Dip | The angle a planar feature makes with the horizontal (0–90°). | | Hanging wall | The block of rock above an inclined fault plane. | | Lineation | Any linear fabric element in a rock. | | Mylonite | Ductilely deformed rock with grain size reduction. | | Strike | The compass direction of a horizontal line on a plane. | | Vein | A fracture filled with precipitated minerals (usually quartz/calcite). | Strike-Slip Faults: Caused by shear

• Wear helmet/boots on outcrops, watch for loose rock and tides, inform someone of field plans.
• Record uncertainties (±°) and measurement method.

• Stress and Strain: The difference between the force applied to a rock and how the rock changes shape.
• Rheology: How rocks behave under different temperatures and pressures (brittle vs. ductile deformation).

Strike-Slip Faults: Caused by shear; rocks slide horizontally (e.g., the San Andreas Fault). C. Foliation and Lineation
