Questions:

1. Describe the mineralogical and textural changes that would accompany the progressive regional metamorphism of a shale under 'Barrovian' pressure- temperature conditions. How would the mineralogy change if the rock was metamorphosed under Buchan or Abukuma-type pressure-temperature conditions?

2. List and explain the six main deformation mechanisms, including a deformation map that shows the field of each mechanism (explain the conditions under which each mechanism operates). Illustrate each of the 6 mechanisms.

3. How do we classify fault rocks? Explain the main types of fault rocks, how they are defined, and how we might recognise them in the field.

4. Explain the various ways that folds can form in different stress regimes, including the mechanisms that cause the different types of folds. Make sure you illustrate your answer.

5. Lineations form in a number of brittle and ductile environments. Give examples of 8 different types of structural Iineations, at least 3 from brittle settings, and explain how each is formed, what its significance is, and how we would use it to make structural interpretations. Illustrate your answer.
