What do you think are the most and least reliable shear sense structures described in this chapter?
What will be an ideal response?
Answer: Deflected markers are perhaps the best indicators. Many S–C structures are good indicators, but may only be representative of the last part of the shearing, and the same goes for oblique microscale foliations formed during dynamic recrystallization of quartz grains and aggregates. Porphyroclast geometry may be more difficult to interpret in practice, and fold asymmetry should be used with care. Importantly, shear sense indicators should always be used together, and if they are not in conflict they are making a good case.
