1. Normal faults -rifted continental margins -form in extension -typical for continental and oceanic lithosphere -jargon (horsts, grabens, listric, detachment) -are they low-angle? -core complexes -Example: Basin and Range, the best of all -the way we think it works, mechanically -balancing cross-sections

2. Can you spot the fault?

3. It’s low angle, but so are thrust faults: KEY: puts young (hanging wall) on old (footwall). The fault markers (slickenlines Etc) are the same.

4. Terminology and mechanism. KEY ASPECTS: High-angle vs. low angle normal faulting; which one generates more extension (S)? The formation of core complexes Major detachment faults. How can we distinguish the low-angle normal faulting Style from thrusting (if only geometry is available)?

5. Basin and Range- world’s most studied extensional province-low-angle normal faulting prevails. Tibet-similar.

9. Breakaway zone; importance of a brittle-ductile transition

10. Inversion tectonics- normal faults become thrusts and inverse faults. A regional system formed in extension is forced to shorten. How it might work

12. Important things about normal faults. 1. Fundamental to structure of continents and oceans.

13. Important things about normal faults. 2. Two different styles: the low-angle and high-angle.

14. Important things about normal faults. 3. Can take up as much extension as compressional orogens shorten.

15. Important things about normal faults. 4. You live in the most famous (and perhaps most important extensional region-the B&R).

16. Important things about normal faults. 5. Extension is accompanied by big-time sedimentation-important for oil formation.
